[eddiemoth]

I ran into Andy Yu - the president of Assurance RC disctributor (alignrcusa.com) this afternoon at the Century RC event in Fremont, CA. I got a few of his Trex 600 pictures to share with your guys.

I just want to drop a direct link to the online Trex600 Owner Manual here (http://www.deeteeenterprises.com/images/T.Rex.600/PDF.Manual/Align%20Trex%20600CF%20Instruction%20Manual.pdf)

[caseyjholmes]

Wanted to inform of the new thrust bearing tail rotor upgrade for the trex 600.
Since it has thrust bearings, there is a thrust bearing channel in the tail blade grips. This makes using the old plastic trex 600 tail blades out of the question, as they ride INSIDE of the thrust bearing channels and won't be allowed to be pulled straight by force of the tail spinning if you tighten the nut on the tail blade grip down. You will be forced to use tail blades with a wider root surface for the new thrust bearing tail blade grips to grab on to when tightened. The Trex 600 carbon tail blades should do the trick just fine.

I learned this the heard way by NOT ordering tail blades after my last crash, when I ordered the new thrust bearing tail. I had stock plastic tail blades on hand for the trex 600, and was going to use those for the first few flights.
Needless to say after finding out, I had to order new tail blades and delay flight time.

Just trying to prevent anyone else from finding it out "the hard way" as well :lol:

[G-MRM]

Here in the new Align painted canopy I ordered for my 600e matches the 600 Nitro Pro I am building..............

[G-MRM]

The first flight of the new canopy !!!

[daniel reese]

I am the proud new owner of a TRex 600 CF!!! Still waiting for the servos & gyro to arrive before I can set it up tho.

For those of you who have both the 450 and the 600, how different are your t/p curves between the two?

[G-MRM]

I never added the Tx setup the the T Rex build site www.ukheli.com but I will post them here for you until I have time to add to the site as the 600n is taking my time right now !

Martin

[G-MRM]

No blades for the nitro but the brothers we out on the field Sunday !

[daniel reese]

It aint much of a build thread- the TRex600 is too easy to assemble to be able to write much about it. It practially fell together!

I won an EBay auction for a new in the box T600CF and finally got the last of the bits I needed to finish it off. A bit less than 10 hours total and it was in the air.

More to come. Eventually, I'll put in a torque tube conversion, the helical maingear and a Century MD500E fuse...eventually.

[daniel reese]

I was thinking...that usually get me into trouble....
The real UH1 and some of the older Jetrangers had a flybar but it was VERY short and was weighted on the end.

Couldnt we do the same thing with our regular flybarred rc helicopters?

The paddles dont really serve an aerodynamic function- pitch is only relevant in as much as you dont want them to have an aerodynamic (positive or negative lift) on the rotor disc. Their function, as I understand it, is simply to provide gyroscopic stability to the rotor disc, maintaining a nearly horizontal attitude in relation to the ground, in effect, giving the pitch changes something to "push" against.

Couldnt the same thing be accomplished by removing the paddle, shortening the flybar and adding an extra collet or two?

Or am I on crack again?

[swatson144]

Put down the glass pipe and step away.

The shape and size has about as much to do with the paddles as weight.

On the other hand for about the same price as 100 rocks you can get the Vstabi virtual flybar etc. and just do away with the flybar and later go to 3 or 4 blade heads

Steve

[swatson144]

Sorry I didn't 'splain it well. If you look at the washout arms and their connection to the fly arms or outer ring you'll see that the pitch of the flybar changes 90 degrees from the desired cyclic effect. Or in other words you twist your flybar and servos move.

Servos move and the pitch on the fly bar changes, it tilts and changes the blades pitch. Without the paddles the flybars pitch change would be about as effective as a cellophane (or Nitrocellulose)crack pipe lol .

Steve

[swatson144]

I've never seen anyone drawn to scale like a "lawn dart to a toddler" until you popped up. I think it's great! You really should have a look at http://scalehelicopters.org/ bottom L frame where Mr. Wales has posted his book. I think you'll find it interesting and informative.

[daniel reese]

you crack me up!
Lawn dart to a toddler...yeah, that's me!

[Crash9]

Is there a batter battery then the Align lipo. I just got my 600 done and my LHS doesn't know when they will get more so I'm looking fgor options. Thanks

[G-MRM]

Thunder-Power are said to be good and so to is the 4900mah FlightPower !

I just have 3 Align ones.

Martin

[daniel reese]

I have 3 Align batts and they're fine; I also have two DN batteries and they're just as good but ALOT cheaper from GrandRC. I just ordered an AirThunder 22.2v 6S 5000mAh but havent recieved it yet- bout the same price as the DNs and a bit cheaper than the Align.

Ive got 44 cycles on two of the aligns, 40 cycles on one of the DNs, and 15 cycles on the other align and dn- they're doing as well now as they did on their first.

[Crash9]

Well I picked up 2 Align 4400 lipos and 1 is bad outta the box. I talked with Frank at Align USA and he will swap it for the TP 4200. The 4400 is discontinued and the 4200 is a Thunder Power pack re-labled. I think this explains why the 4200 is $20 more at Hobby Town where I purchased the 4400s.
I'll be getting the Airthunders when the time comes or maybe the A123 Li-ons

What mAh are the Align Lipos your using?.

[daniel reese]

Sorry for the long delay
Two Align 6S2P 4600mah 20C ($246 each at LHS)
One Align 6S1P 4600mah 20C ($226 from Grand RC)
Two DN 6S2P 4400mah 20C ($190 each from Grand RC)
One AirThunder 6S2P 5000mah 25C ($266 from AirThunder)

The three aligns are practically indistinguishable from the DNs but the AirThunder definately stands out as being stronger...obviously.

[Eagle513]

Ok here is the question from me...

I am going to go get a DX7 tonight after work, and it comes with the AR7000 Receiver :) the TX :) and 4 DS821 :) or so I thought?

I was doing a quick search on the net looking for anyone else that uses the DS821's in the 600. I didn't find much, except for a link to a forum, Heli...Something, that their tech support was telling someone that the DS821 would not work in the 600. I was wondering if there was any truth to that. They didn't explain why they wouldn't work, so it left me wondering. If they don't work in the 600, then I don't need to pay extra for them. If they will work then great, I will get them with the TX.

Help me out here, I know you all can do it.

[swatson144]

I don't see why they wouldn't work well. I don't have a trex 600 but I am using them on cyclic on my H550 (smaller heli) and well pleased for now.

I'd think they were good enough for me on the 600. They may or may not be good for hard 3d but I know I'm not good for hard 3D.

There have been reports of the output shafts breaking off the DS821s but mostly on planks. I knew about that before I bought mine to use.

Rick is using 4X on his 550 and says he is happy with the way it holds on the tail also.

Great, that's good enough for me to buy them and try em. I will write up what I think after I get the 600 to put them on.

I think that other place is like quite a few others that I have seen, they talk great about what they use and horrible about everything else just because they don't know.

[swatson144]

I figured when I look at the specs they were about 80% as good as the best and I ain't.:). 20$ each is about the going rate and as long as others "require" the best I'd keep using them.

Steve

[Eagle513]

I just got back from the LHS and I bought the DX7 with the servo's, I don't think they were going to make me that good a deal without them anyway. I wasn't too concernedI still got the DX7 at a fair price and I am happy.

Just for fun too, I bought a GY401, so far I have been using the telebee gyro.

So more later, I have to read the manual cover to cover now.

[G-MRM]

I have used the DX7 servos in my T Rex 600 nitro, see my web site, and Ok so far.

I have read the out put shaft can snap, I also see that the don't recommend then for 50 size nitros but..... I am not into 3D and they are fine for mild sport flying plus a electric version will not have the vibrations !

Martin

[swatson144]

Nice to know Martin. I knew you'd found a handfull of DS821s but didn't know they were installed in the 'rex.

On the shaft breakage it seems that using any loctite like product attacks the plastic of the output shaft. Horizon has said as much. http://www.horizonhobby.com/Products/Support.aspx?ProdID=JRPS821 and I've accepted that as an answer. Right wrong or indifferent I'm flying with my decision until something else comes to light.

72oz/in with the hole in the arm 1" out from the center of the output shaft it'll lift 4.5 lbs. Sounds suitable to me. The arms are a little disappointing and that could be the reason this all started. As in I don't recommend the DS821 servos as the supplied arms don't work. HD JR arms or HD JR from dubrois will set you straight if so.

I have a hard time buying that JR/horizon has a defective product out and aren't doing a gross recall.

Steve

[G-MRM]

I have another 3 of these servos in stock, to be used on another T Rex 600 Sport version.

I did see the thing about loc-tite and can't see why anyone would add it there ! Align are selling servo disks to fit JR and Futaba, I have a set of JR ones and they are well made as in strong.

Martin

[Eagle513]

I don't think I will have much to worry about. I don't plan on any crazy 3D. Or really any 3d for that matter. I will probably put some better arms on there if they have a problem. But that is not a big deal at all. I am looking forward to getting this 600. It is going to be a ton of fun.

[skyhunter357]

I have my Trex 600E on Agusta 109A and it fly very good. also if your interested i have fuse for sale. email me at patinio@sbcglobal.net

see video: http://www.youtube.com/watch?v=May5ixmN54c

[Eagle513]

Why is there a step down regulator for a Gyro and servo setup that both say can handle 6 volts?

I have a Spectrum AR7000 receiver and a GY401 Gyro driving a DS821 servo, everything should be a nice even 6 volts, so why the regulator to bring it down to 5.1?

I don't think I need it, but everyone seems to me like everyone is using them, am I missing something?

On another note, I have the DS821's for the TRex 600 here and they handle great, I know now why everyone thinks they won't work. They are physically a little larger than the futaba servo's everyone raves about and you have to shim them out a little on either side to get them to fit. Because they are a little larger without the spacers they won't bolt in. I made some nice little spacers out of some extra plastic and they work great. That runs you into one more problem though the canopy now rubs the servo arms. Not much, but they do rub. I am not yet convinced it is completely because of the extra spacers though, because the canopy is rubbing on the main driver gear. Figure that one out, when you look at the open end of the canopy off the heli it looks like it is defective, like the flares on either side to make room for the gears are warped inward. It's odd, and not much of a bow back inwards, but it is definatly shaped what appears to be wrong. I am going to take the canopy with me to the LHS and compare it with one there. Maybe it's warped, or maybe the crack pipe is getting to me again. :)

[Eagle513]

Bump for unanswered question, kinda important.

Thanks.

[Sleepstalker]

If you are determined to use offsize servos with the shims that is fine as long as they provide the control that you want. If your canopy does not agree with this setup , a good Dremel type tool with a sanding drum will carve you nice clearance on the upper edge of the canopy...Dang ! Mo money on toolz...8)

[swatson144]

To answer your Q, The reducer is required for the ever popular S925X servos. They are pretty much souped up and over volted on 5V and won't last on 6. You don't need it on your setup. The manual for the GY401 rates it at +4 to +6V. The DS821s are rated to 6V.

Rick is running a DS-821 on his H550's tail and says he is happy with it. We both have DS821s on cyclic and had the same "don't fit so good" problem. I didn't use any kind of an adapter but didn't use the rivets in the servo grommets (on Ehelis I usually hard mount the servos).

Steve

[swatson144]

On the canopy dragging. I'd probably stuff it with paper towels and apply heat to see if it would take a set slightly outwards (assuming plastic). You'd want to make sure a replacement wasn't priced to bad to consider though as some plastics go from malleable to molten in a couple degrees.

Steve

[Eagle513]

Ok that makes sense, I was almost positive that the setup I had didn't require the stepdown. There were just so many people saying you had to have it that I started second guessing myself.

The fit issues with the servos, I did use the rivets and the grommets both too get them to fit, although I guess it would probably work just fine without the rivets. Without the rivets though doesn't that put the backs of the servos directly against eachother?

The canopy is fiberglass , I don't think a heat and stretch will work, but it might be work a try, I was try to find something I could make a spacer to brace it out just a little. I tried one set of braces, but it pushes out so badly that it doesn't want to stay on the original pegs.

I appreciate the answer on the servos, I want to finish tidying up the wireing and I wanted to get a definate answer before I wrapped the rest up. Everything is going to be very nice and neat. No crap wireing on this bird.


Thanks again Steve.

[G-MRM]

I used the smaller JR servos on my 600e they don't have much room but it a shame the ones your using are a little on the big side. I have used them in my 600n but the frames are wider to get the engine in ! Maybe mod a 600n canopy?

9254 need 5v but remember a fully charged 4.8v battery pack say 4300mah will hold a good 5.5 or more volts for the first few mins, the BEC gives out 5.8 however I still used it for the tail servo !

Martin

[whirlymind]

Eagle;

I am a total noob to the 600, and am in the process of building a 600GF kit. I am planning on using the 821's, so this is very interesting to me.

I am going with the same setup you have, so let me know what you did on the canopy clearance issue.

I have heard good / bad on the 821's for tail drive servos. I would like to use them, as then they are matched. As an alternative, I was thinking of the tower digital 160 servo. Any thoughts?

Thanks
Terry

[G-MRM]

Hi I used 591servos and never had any canopy problems. I am sure whatever servo you use you will get on Ok as there are lots flying with all types of servos fitted.

What spec are these for the tail and what gyro are you going to use?? You can't better a GY401 and S9254 for the money !

Martin

[swatson144]

I think I'd use a 821 before I'd use the tower 160 since the specs are so close. My friend Rick is using 821s on a H550 and is very happy. It really depends on your skills. If you are running around backwards you want nothing but the best you can afford. Rick's holds well against pitch pumping and cross wind etc.

S9254 at .06 secs vice ~.16 is no comparison. My skills don't deserve them but I run 9254s just so if I don't like the way the tail is behaving I don't have to replace a servo with a 9254 to rule that out.;)

Steve

[321gator]

I find it strange to this thread just ends at this date. I know there are more Trex 600 owner out there. Anyway, here is my 2 cent's you can use to DS 821's (I have them in mine) But you need to put in longer horn screws to stop the shaft from breaking!!!! I will try to find the link on this.
I am looking for someone how has used A123 in their Trex 600 I am looking to upgrade to 12s or 14s A123 in mine. I think I'm going with a CC85HV ESC and Z50A 600 Motor? Looking forward to what anyone have to say.
Thanks,

Hi Gator, I'm using 8s2p A123 cells at the moment with the standard 600XL motor & a CC110HV ESC. I am only a beginner so fly mostly tail in & a bit of side ways forward flying. I have tried 12s A123's for one flight & it was awesome, the motor got to hot at 65c so I am looking to upgrade the motor, CC recommended a Neu 1912H/1Y, I have heard Neu's have bearing problems ?

What have you heard about Z50A 600?

[321gator]

Hey TeeDee,
Well from what I have read, the stock 600XL can not run over 6s you are running 8s and it is doing ok but you maybe shorting it's life, ( buy the way once I get my New motor. I will be selling my stock 600xl and ESC It ran once as a bench test only. ) . But when you put a higher Voltage to the motor it will get hot. I read on another forum that I need to run a motor with lower KV. like 600, 595, or even 800 the Align 600xl is like 1600 kv's The motor that I am thinking of using comes under many names Z , Century, Tonic-x, and thunder tiger and others but it looks like they are the same.

I have read about the bearing trouble with the old Align 600L motors

Gator.

[TeeDee]

Hi Gator,

Yup, was well aware that the 600xl is only rated 6s but I have been flying it 8s for 47 batteries so far & the motor is not overheating, can hold my hand on in indefinitely, measures around 45c with temp gauge. Any how if it fails it will mean I have to upgrade immediately lol

Think you are right with the KV rating, the Nue motor recommended is 825KV so with stock gear & pinion would theoretically give me 1730 headspeed so would probably have to go for a 14t pinion for 2400 headspeed.

If you get your motor before me let me know how it turns out, I will do the same !

I think the bearing problem was the old 600 motors (hopefully) my understanding is the later ones are OK.

[swatson144]

8S A123 runs only about a volt or 2 over 6S lipo under load.

A fellow runs one with rotor works frame on 14S at the field, and does very well with it. He uses the MEC solderless (http://www.modelelectronicscorp.com/browse_product.php?pid=29) double barrel shotgun configuration. There are several others running the MEC battery setup in other helis and seem to be happy with it. I asked Richard about balancing (no taps) and He seemed to be happy with just a slight over charge every 20 or so cycles, which sorta makes sense. The M1s are tolerant of an over charge so in theory if you charge the pack to 3.8V / cell you'd fully charge any cells that were only getting charged to ~ 3.4V on a normal charge and no harm to the pack. Then again many people don't balance A123 as they have no minimum voltage like lipo (or it's so low it won't keep a heli in the air). IDK as I have built my packs and have taps on them.

Both the Neu and the align motor had some early problems but both have been redesigned. The bigger Neu H series motors have larger bearings and a fan. I have an old 1907 1.5Y in the swift and it has done very well.

Anyone running one of the new Scorpion 40mm series (http://www.innov8tivedesigns.com/index.php?cPath=21_25_68)? I'm sure liking the little one I put in the H550 and if I was to be looking for a bigger motor in a bigger heli I'd sure be giving it the eye. They were supposed to have a 35mm series out in june just for the Trex 600 etc helis. Ain't seen anything more about it so maybe the 40mm will fit. There are many people runing the HK-3026 series on the trex 600 and happy with it 75$ hard to complain, but that's what I have in the H550.

[321gator]

Aloha,
Where to begain. First to TeeDee If you look @ your motor you should see a ser# The Align 600 Lx with the number don't have the bearing and shaft problems. I have been thinking about the CC110HV ( how do you like yours) verse CC85HV I can get the CC85HV for $150.00 USD new the CC110HV is $229.00 and the Motor around $124.00 so I am looking @ 300 and I still have to get the A123's they are running around $8.00 to $9.00 each delivered.

Hey Broggyr, I am sorry I only have the one, and I think I am going to keep it for awhile.

Hey Swatson144 what is a HK-3026 series can you run A123 14s with it? Do you have a link that sell then @ $75.00 USD?

Thanks
Gator
Cocoa, FL USA.

[swatson144]

Just click the blue print in my earlier post for the link to the 40mm in the left panel of the site is the 30mm. As I mentioned it's probably not the best of choices since it seems perfect on my smaller Hurricane 550 but others have run it on the 600E and were pleased. The 4025 650 kv would be where I would look for 115$. You'd want to make sure it fits the stock frame.

Steve

[broggyr]

Hey Broggyr, I am sorry I only have the one, and I think I am going to keep it for awhile.

Dang! It was worth a shot :D

[321gator]

Aloha everyone,
Frist thanks I will look at the motor. and for TeeDee I saw this on another link.


The 75a ESC works just fine. If you are going to upgrade your motor, why don't you go with the new 650L motor. The shaft and bearings are bigger (Two most complained 600XL failures) The motor has more torque than the 600XL also. The price between 2 motors are basically the same.

So it look's like we both have a so so motor.

Gator.

Hi Gator,

I so far like my CC110HV, it has never got past mildly warm in all of my flights, i have not used any of the fancy governor features yet, will wait until I am properly set up on 12s A123's. Looks like my 600xl motor is OK regards bearings and shaft etc.

Can you really get A123's for $8 -$9 ? I have paid $16 (about $20au each), maybe you can pick some up for me :D

Here are some pics of my setup, like swatson144 was saying I use the MEC solderless tubes as well.

Gator I run 8s2p at the moment, hence the 4 packs of 4 cells. I intend to run 12s at some time in the future.

Sorry, don't know about the B&D packs :confused:

[321gator]

Aloha,
No No Don't be sorry I saw the pic and it look likre that yo had more batt's then th e 8s. oh1 I need to get you the link for the batt's A123 for that price . Are you in US?

[321gator]

Hey,

Gator

[TeeDee]

Hey,
TeeDee I count 16 In the pic's you posted?

Gator

That's true Gator, 16 batteries, but I have 4 cells per pack (and 4 packs=16 cells), then I have two, 2 packs in series and they are then joined in parallel at the ESC plug, hence 8s2p :)

Naw mate, not in the USA, in Australia :D

[321gator]

Well the Pro version of the 600E that was suppose to never come out - is out! Too Cool!

Price is killer too! $688 including new 650L motor, 100A ESC, 6A Regulator, Torque Tube, all Metal Head, 3K blades, paddles, and tail blades! WOW!

I dig the gyro tray. No more removing the gyro from the boom block when changing stripped torque tube gears! Cool!

[FlyGuy]

The description I used was from the previous owner.
I have not got this bird yet.
I should have it in my hands by next week at the latest though.

[FlyGuy]

I was told I should put on metal blade holders.
Any other suggestions on upgrades before I start?

[mtpenguin]

Man that looks nice......


It will probably fly a little better than my Rappy 50 N!


Don't forget to hit Steve (swatson144) up for battery advice. He da man!


B-)

[FlyGuy]

Oh yeah, what about the stuff I still need?
Any suggestions?
Gyro & servo combo
Battery
charger for battery
I have a spectrum DX6I TX
But, what rec should I use?
Any comments will help. as I am a noob to trex600

[FlyGuy]

ok...
Hey Steve,
Got some battery advice for me?

[FlyGuy]

:D I am SO HAPPY ! ! ! :D
Can't wait to get the rest of the parts I need to get it going.

[swatson144]

I know what you mean. I've been picking at putting a new Swift in the air. :D.

Nice looking heli and a great price. 1600KV and 13T it should be a rocket.

Steve

[renelu]

Flyguy - I replied to the battery and charger post before I saw you had your setup in this thread. Looks like you got a good deal on it. I tried the helical gears for a while before I jumped to a high voltage setup. My 600 was a lot quieter in the air with it and I did like using them. Some other sites reported bearing problems and broken motor shafts purportely due to the increased side loads on the motor (more surface contact and whatnot). Just thought I'd throw that out there. If you go HV, then you pretty much have to go back to the straight gears.

If you have the 3D landing gear, use that instead of the landing gear in the picture. I never liked the other type of gear because it flexes to much for my taste. I never had a problem with them, but the T-Rex 450 I used to have broke many landing struts (without crashing).

[FlyGuy]

I figured I would use what I have for now.
Although, if I do run into problem with the mg I will go back to straight.
I did find a set of landing gear for this that is aluminum and has shocks.
So, it will absorb harder impacts. When I can afford them I will prolly get em.
Here is a link to them.
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=260291917103&ssPageName=STRK:MEWA:IT&ih=016

[mtpenguin]

Those are interesting enough...........

Wonder how *much* heavier they are than stock.

I like the wider stance.


B-)

[renelu]

I wouldn't bother with that gear unless you're just like the look. It looks like the builder has some machining skills.

The 3D landing gear from Align is shorter, beefier, and angled, compared to the stock one - it holds up pretty good, and is probably the cheapest part on the heli.

Of course, I just looked for a set, and they look curved now instead of angled. I guess it has been awhile since I had to buy a set. Look up "T-REX 600 3D LANDING SKID" at allerc 's website. Normally $5.99, on sale for $2.00.

(silly spam filter... I can't post a link yet)

[FlyGuy]

I like the wider stance also. But, for the price... not sure.
renelu: thanks for link I am checking it out now.

[swatson144]

What are you going to do for blades?

It seems you are pretty much just hovering around right now? So from the other thread (http://www.rchelicoptertown.com/forum/showthread.php?t=2853)you've decided to go with 11t (good choice IMO for hovering and FF). You may consider turning down the throttle curves to ~85% and running woodies. That should put you down to about 1600 rpm and lower the cost of crashing. To this day I still put woodies on for test flights and other occasions. Heck it wasn't too long ago they were all I flew.

Another blade worth a look are these cheapies helimax (http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXJPJ1&P=0) blades are inexpensive and usually quit nice for my skill level. Sometimes they are out of balance but usually right on. I've shortened about 6 pair on the ground, and all but the pair I'm currently using required no balancing and it needed about 3g of tape.

Steve

[FlyGuy]

I already have a pair of woodies for it. There are the maverikk brand.
I haven't set up the DX6i yet though. I thought I would have the LHS help me with that. And get any bugs out of it first. Then I will copy the setting a couple times, and play with those a little.
I plan on buying the gyro w/servo tomarrow. Any recommendations?
I was thinking of the JR770 3D Gyro with 8900G Servo Combo pack JRPG7703DC.
But, I am also looking at the LogicTech 6100T/6100G Tail Lock Gyro/Servo combo.
Or the Futaba. GY401 w/9254 FUTM0808.
For the money, is the Curtis Youngblood Solid G Gyro worth it?
Anybody know?

[swatson144]

Any of the gyros mentioned will do you proud. You can add the Spartan and BLS251 at the top of the list though. At that level of equipment it gets more into personal preference than difference in equipment.

Don't be scared. Just set your own radio up. It's time consuming but not exactly rocket science. Generally when you have someone "help" you he winds up doing it and you learn nothing, so after the 1st crash you are back to being an idiot. It's pretty simple really, just start with the factory rod lengths and build the heli. Set the radio up so that everything moves in the right direction, then adjust, and adjust until everything is square and the pitches are right. I've done a few and even setting up the 2nd swift took ~4hrs to get right and I'm pretty doggone familiar with my radio and the Swift. Most all the eCCPM helis setup the same so reading about the setup on a your radio on even a trex450 can be very helpful and probably easier than following a setup guide on the 600E with a different radio. You can always have someone check it when you are done, but by the time you are done you will know it is right. Besides we are here to help anyway.

Steve

[mtpenguin]

right on Steve!

I did my own setup with the nitro, and was so scared I had it screwed to a piece of plywood the first time I started it! With an electric, I'd have more confidence in the ESC to be able to spin it up at my own pace, making sure everything is working like I expect.

Your right, the only way your learn is to make your own mistakes and recover from them. Like taking the muffler plug out when starting a glow engine...... :)
Or taking the engine / heli completely apart because the bit in the F'n drill was slipping!

LOL

I wouldn't have the discipline to NOT spin it up at least a little bit before I brought to a test pilot.


B-)

[FlyGuy]

I just got the Futaba 401 with servo.
The lhs website says the JR is the one they run.
When I went in, they all said the 401 was the one I should have. lol
Got the spektrum 6200 rec
Now all I need is a good battery and charger.

[swatson144]

I keep thinking about trying 2 of these in series as 6s http://www.swanghobby.com/product.php?productid=2&cat=14&page=1 or maybe 3 of the smaller ones on my HV swift. No recommendation just a thought and I've taken more expensive gambles.

Steve

[FlyGuy]

I was thinking of some of those options as well.
Thanks for the link.
I'm setting it up with the spektrum 6200 rx and DX6i tx.
Anybody know what settings I should use?

[swatson144]

It's really not that easy. There are dark forces at play and you must use your own magic. No really small changes from one heli to another makes too much difference in the setup. It'll take longer to get everything right than just to do it, that's why we don't have threads with our settings posted for everyone else to use. We aren't exactly secretive.

Some tips though.

1. Set the swash type 1st. Changing swash type erases everything else in most radios. you need 120 degree

2 before trimming any servo arms fit them 1st. This means don't cut any extra arms off etc. The splines allow you to get the arms on straight simply by rotating them and trying in 90 degree increments. This will help avoid using much subtrims. Hook all the servos up (motor disconnected) and power the heli up.Select IU1 and exactly center stick (look at the graph in TC) ensure the trims are center. This will have the servos in the proper position to begin. trial fit the arms. and begin connecting linkages.

3 if you are using digital servos expect some noise, they do that.

4 get everything moving in the correct direction. you can reverse functions in swash AFR by changing the + to minus by scrolling through zero and continuing. you can also reverse chans in the reverse section between those 2 you can make it work. If it's all incomprehensibly screwed up try switching the aileron and pitch servos. IMO that's sorta like having an only slightly screwed up Rubiks cube it's really not any easier unless you already mastered the puzzle. It all really is pretty simple once you get your mind wrapped around it, much like the Rubiks cube.

5 the 6I has a loud beep so don't try this at night and anger the family.

You get everything working in the right direction and all arms square, then it's simple linkage adjustments to get 0 pitch at mid stick. Then simple pitch settings in swash to get full + - pitches and max cyclic. Then all that is really left is taming it with dual rates and expo and setting up the tail. I always setup as bad as the heli will go without binding in swash and then tune it down in the other radio functions (servo limits, dual rates etc) to get it tamed to what I want. This allows me to dial it up without worrying about anything as the swash setting are the upper limit and everything else is fine at 100% but faster than I like.

Steve

[thumbtime]

5 the 6I has a loud beep so don't try this at night and anger the family.

lol how many times has she said to me "do you have to do that now" lol
(ov course i do love its dark outside lol )
and mine is optic6 i dont know if it is any less noisy but i had my ear bent with that one

[FlyGuy]

ok, after spending 3 hours at lhs and 2 people helping me, we finally got it done.
It seems the person I bought it from didn't have a whole lot of experience either.
There were a lot of things that had to be redone. the entire tail section for starters.
I had to actually get new pieces because he had stripped the originals.
$80 later...
I finally have something that will fly.
IF I had a battery and charger...

[mtpenguin]

Hey! good to hear. I was wondering why I hadn't heard from you. Sounds like you got the better of it. Now, win that charger from this site, and you'll be half way there!


B-)

[FlyGuy]

That would be REALLY nice.

[FlyGuy]

Thanks to all for the help.
I can't wait to get this thing into the air.
I know I will have to be careful, to much money to just crash.
I have figured what it will take to get video onboard also.
But not cheap, as I will be doing HD camera work with it,
One step at a time, I still need bat & charger, balancer, etc.

[FlyGuy]

A used 5000mAh 6s1p came in today. paid $100 plus shipping.
It's a kong power battery.
A charger will be next.

[swatson144]

Congrats. that pack should make you happy and the KongPowers are not easily damaged by over discharging. Good news for both of us as I got 2 10 cell packs of A123 off ebay for about 103$ each. Hmm I wonder what I can do with them? :D There may be a 15S 600 in my future.

Steve

[FlyGuy]

Maybe just go for the 700 instead?

[FlyGuy]

I did spool my 600 up.
The mains were tracking a little off.
So, I adjusted them to perfection.
Don't want to use to much battery until I can charge it back up.
It was sent with a full charge :)

[swatson144]

Was it a little more intimidating? I can't afford the care and feeding of a 700. You got any idea how much it costs to take one of them to the vet?

Steve

[FlyGuy]

Yes it was MUCH more intimidating.
We have a local vet here for align parts.
And they are not so bad for prices.
As I have been feeding my 600.
But, it is a hungry beast. :)

[swatson144]

Our parts store has a flying field8). Sometimes it's handy that way:oops:

Steve

[FlyGuy]

I have a beautiful field less than a block away.
It even has a landing pad. lol
Not really, but it is a 8 foot square slab.
And the local heli store is moving just down the street this summer.
Works real good for me. :)

[FlyGuy]

Went out into the street in front of my house today for maiden. 0 degrees F
Hovered well for a few minutes. Trying to get trims set.
Car comes by, and I go to land, landed a bit hard.
Broke the landing strut. And touched the blade tips.
I went to LHS and got 3D struts replaced them and went out and flew again.
I was shaking pretty bad. Not from the cold...
I called Mtpenguin to tell him of my adventure.
In a calm voice of reassurance he says, "is that all you broke?" lol
I am charging the battery again, and am about to attemp another flight in a few minutes.

[FlyGuy]

This flight went much better.
About 10mph winds, 6 Degrees F.
I noticed some drift, but not much.
Still shaking though. this time a little from the cold.
But, mostly just my nerves.
It's a lot different when you got a lot of money in the air. ;)

[mtpenguin]

so, this was your first completely successful maiden voyage? Excellent!

Go FlyGuy Go!


B-)

[FlyGuy]

with a ccpm... yes it is.
I guess you need a good heli to be able to fly good. lol

[FlyGuy]

Hey glograph,
That site has NOTHING to do with heli's.
Go spam elsewhere ! ! !

[FlyGuy]

Today’s last flight with my Trex 600
I had the battery charged and it was balanced.
I thought to myself, my kid has been around helicopters before.
I should take it out one more time for the day.
So, I went outside one more time before the day is done.
Everything starts well as I am hooking up the battery,
I notice a little more wind than this morning.
But, this morning’s flight went really well.
This time was much different…
I take off, everything is good.
I lift to about the height I was this morning.
Going good… And WHAM !
The wind lifts the heli far more than I expected, in just seconds.
I could fit 3 mobile homes end to end from me and the heli.
( approximately 150 feet ) I started at about 30 feet.
Suddenly, I see from the corner of my eye my autistic son running towards the street.
I get panicked, I am trying to regain control over my bird, and call my son to come to me.
The bird is not coming back down; in fact, it is still going up,
and my son is not coming towards me. He is still going into the street.
My heart is jumping out of my chest at this point!
And I begin to shake.
( I was not in 3D mode) So, I only had 3 deg. Pitch down.
Needless to say, I wasn’t thinking about this at the time.
As I see other kids coming out from a house across the street.
I get the bird steady, my son has stopped. Things are looking up.
I give the heli a slight back motion, and begin its descent to get it toward me again.
The wind carries it backwards at a high rate of speed.
I quickly compensate to begin forward flight again.
Still shaking badly, I start to bring it down closer, (now about 50’ in the air)
As I keep it coming down, I look to see my child beginning to run toward me. (finally)
But, the bird dropped faster than it was when I began the descent.
I rip the stick up and begin to climb again, nearly missing my yard light.
I am shaking so bad at this point the TX looks like it is blurred.
About 25’ back into the air now, and coming in again for the landing.
I look over at my son and see blood coming out of his nose.
WHAT THE H#$&?
I finally get the bird down, disconnect the battery, and run the bird & my son into the house. I AM FREAKING OUT at this point.
My son sees how scared I am and how much I am shaking and begins to freakout as well.
After getting him into a bathtub, I see that it was just one of his usual nose bleeds he gets from nowhere. He gets those about every 3 months or so. I get it stopped right away.
About 35 minutes later my son has calmed down.
I am still a mess. Even after 2 hours I was still shaking from the incident.
Writing this has my heart rate up more than normal. Just thinking about it.
And it is several hours afterwards. Whew…
I will not fly when my son is around anymore. Unless, there is someone to watch him.
As I am a single parent.
I learned my lesson!

[mtpenguin]

Wow!


LOL


Had me worried there a couple of times.... Glad I wasn't reading a heli-obit.



Did you get a video of this? <tease> prolly not.


I know what you mean about the shaking. It is one thing to get yourself in a situation that scares you. It's another to try an get back to a normal mode after you start to shake. It is tough to calm yourself back down enough to bring her home.



Good job keeping it together.



B=)

[FlyGuy]

It's pretty bad video from a cheesy POS.
And from the heli's point of view.
But, yes I do have video of it.

[mtpenguin]

LOL is there audio with it? hehehe


(OH S!#$@, oh, oh, oh... oh-oh)


etc.


B-)

[FlyGuy]

Sorry, no audio.
I can't figure out why the audio is not working yet.
Although, I will be looking at it a little closer in the future to remidy the audio.
But, I think your interpetation was just about spot on ! ! !

[FlyGuy]

Any ideas out there about expo settings?

[FlyGuy]

I got to fly in the local arena and theater this week.
Had tons of fun !
Not a lot of room for the 600 in the theater though.
Just enough for a good hover. lol
But it was fun none the less.

[FlyGuy]

When the LHS helped setup my bird there was no expo.
I hoverd around the first couple times with it that way.
VERY TOUCHY !
I was talking with another pilot that told me about expo.
But, not really how it worked or really what to do.
He just said, "turn it down, mine is at about 35"
I didn't know what that meant.
But, I went into my setting and saw a % that said 100%
On Aileron, pitch, rotor whatever...
I turned them all down to 70%
And found that it calmed the bird down some.
But, was afraid to turn it down much more. (In case of wind gust/recovery etc.)
After reading several forums on the subject, I played a little with them today.
The % on the DX6i is the amount the swash moves.
The +/- next to the % is sensitivity on the sticks.
I left it at 70% and took the the other to +40 each.
I set it up where one switch flips all to those settings in D/R Combi.
I will try it tomarrow to see how it handles.

[swatson144]

It sounds like you are changing the dual rates settings or end points.

Lets have a look at a fictional heli. Since this is a fictional heli we will ignore some nuisances like gravity, gyroscopic precession (http://www.copters.com/aero/gyro.html) and linkage ratios. This heli if setup by the manufacturers recommendations would give +- 10 ° on collective and 10 ° on cyclic. Being that linear the heli could focus as much power on pitch and roll axis as it could on going up. Simply put it could roll with the same amount of force as it could accelerate upwards which would make it a blur at full cyclic. Now most pilots would have a hard time with that so the TX folk have given us 2 ways of dealing with it.

Expo: A way of changing linear stick input to make an exponential change in the servos movements without changing how far they move at full stick.
To quantify what occurs with 0 expo on our FH (fictional heli) if the ails/ele stick is centered we'd have 0 ° cyclic on that axis. Moving the stick 1/2 way (meaning moving a centered stick mid way to the extreme) in any direction would give us +-5° on a blade depending on which we were looking at. Moving the Stick all the way would give us the full +-10 °.
To quantify what occurs with expo one could move the stick half way in either direction and only see +- 2.5° while moving to the full extreme would still result in +- 10°
Or as Futaba puts it (whichever is easier)
Exponential: changes the response curve of the servos relative to the stick position to make flying more pleasant. You
can make the servo movement less or more sensitive around neutral for rudder, aileron, elevator, and throttle (except HELI
type - use THROTTLE CURVE instead).
Why use expo? Many models require a large amount of travel to perform their best tricks. However, without exponential,
they are “touchy” around neutral, making them unpleasant to fly and making small corrections very difficult. Additionally,
by setting different exponentials for each rate, you can make the effectiveness of small corrections similar in each rate,

Dual Rates: This is simply limiting servo movement electronically to less than it can travel. Our FH with 50% dual rates would still only see +- 2.5° at 1/2 way in either direction but the difference would be that at full movement of the stick one would only see +- 5° on the blades.

Most computer radios will allow you to use any combination of expo and DR and even assign them to flight modes. ie you can use "taming" expo (I say taming because JR and Futaba are opposites) in IU1, no expo and reduced rates in IU2, and 100% rates and "I don't want to bang sticks" expo in IU3. The choices are nearly infinite with todays mid level and up transmitters. It's laid out like a buffet for you to decide what you want and how you want it.

I could tell you what I like but you ain't me. One other point on the subject is swash settings. Don't use swash settings (swash AFR in Futaba speak) to tune your heli as long as you have the swah setup IAW the manufacturers recommendations and check for interference and binding you can do whatever you please with the DR/Expo and not have any unpleasant problems later when you want faster response.

Steve

[FlyGuy]

Thanks for that more in depth explanation.
I just had to wrap my head around it today.
I am still getting use to terminology and effect.
I should have wraped my head around this before I started flying.
But, noooo I have to jump right in there. Glad I did though.
I love this stuff. I'm addicted just like everyone in here.
No crashes yet on the 600 just lucky so far...

[FlyGuy]

Well, I spoke to soon...

I crashed today.
Nothing too bad, got my list ready to go to the LHS Monday morning.
mains blades, tail Blades, flybar paddle, flybar, stablizer tail piece,
canopy mount, ball links, and a linkage rod.
Total damage about $100 at LHS
In the back of my mind, I knew it was going to happen.
Glad I got it over, without too much cost.
Best flying I've done yet. It was beautiful. (up until the crash)
Didn't use the new expo settings. (tried a few times)
But, switched back to what I had before.
I will play with those a little more before next flight also.

[swatson144]

Sorry to hear about the inadvertent interfacing with terrain. Unfortunately it won't be the last but hopefully they won't be too close together. I've had several months with 3 crashes in them but fortunately the seem to be coming farther apart.

I don't particularly like expo since at some point you hit the "ramp" where the cyclic rate goes up drastically. Other people love it. Myself I recommend heavier paddles to tame it down a bunch and not grossly affect the flyability.

Steve

[mtpenguin]

And since your replacing them anyway....... Might be a good time to try the heavier ones.

B-)

[FlyGuy]

Sounds like a good idea. Think I will.
Hope the LHS sells them. As I will be going there in about an hour.

[morkelkey]

Hi dear friends,
You will be forced to use tail blades with a wider root surface for the new thrust bearing tail blade grips to grab on to when tightened.
Fly today,
Tomorrow you late !

[FlyGuy]

ok....
So, what does that mean?
