[Kaw1000]

Im in the process of building an all aluminum head for my mx 400....the square piece on the top part of the head where the fly bar goes in.....It is bigger than the original plastic part....do I need a longer fly bar because of this?? Thanks

Kw100, I just replaced mine. No you can use the same fly bar. I need more red bling on mine too. How do you like flying an X400 Kw100?

[Kaw1000]

Sweet looking bird there!! I see you have some lights on it!!.....well I'm still In the building stages.......have'nt flown it yet...Just got a honeybee king built.....I let a guy who knows alot about helis fly it.....He got it all trimmed out for me and it flys great!
will keep ya updated on the mx400!!

[eddiemoth]

Well... I am feel so guilty....that is not the latest picture. The latest picture is below. :( I am half way through to get it fly again.

[spectre]

Ouch Eddie...

I see lots of needed parts.

How long befor you get back into the air with this girl?

[Sleepstalker]

**** Eddie that sux..look on the bright side ....maybe that was your very LAAAAST crash...least I hope so...Sleepster... 8)

[eddiemoth]

Hi spectre,
It will take me a while to get it back in the air but for sure it will fly again. :)

Hi Sleepstalker,
I am sure that is not gonna be the last crash but we can always hope, right? :)

[Kaw1000]

owww dang........is this what I have to look forward too??.......I'm staying low and slow for awhile!!
Sorry bout the Crash!!

[eddiemoth]

Hi Kaw1000,
We heli pilots will not avoid crashes completely even professionals crash. But most of the time I crash because I am pushing myself over the limit and impatient. They say the higher to go the harder you fall. I know it is easy said than doen, but if you take it slow and easy, you wouldn't crash as much.

Hi Kaw1000
I wish staying low did help avoid crashes :wink:
I crashed my Raptor last week and I was low with training gear on :cry:
All it means is that you have less pieces to pick up and they are spread over a smaller area.
I dont think I know any other R/C hobby with as high a crash rate as heli's, but we love them and when it goes right it is sooo sweet. :D

[swatson144]

I took my X-400 down today and dusted it off. Ran 2 packs through just getting re acquanted. I have no idea why I've let it sit so long. Last time out may have been 2 months ago. Great flying heli and the tail is like it's on rails, except when I hit the 9 min mark and then it starts to hunt (low battery). I actually remembered this time and didn't bother with trying to figure it out only to hear the lipo alarm go off 30 seconds later. I'll be getting it out more often well until the next crash.

Came back looking like it did when it went out.

Steve

[eddiemoth]

I also need to get back to my MX400. I have been feeling guilty by not having time to fix it from my previous crash. So I need to get back with it. It looks prettey good Steve. I see some red parts!

[swatson144]

Dang man. It's not still lying in the lawn is it? :P

I put the red parts on because they are easier to find after the crash.

Steve

[eddiemoth]

Dang man. It's not still lying in the lawn is it? :P

I put the red parts on because they are easier to find after the crash.

Steve

OK, it is now not lying in the lawn any more. It has been fixed today (after about 6 months of colleting dust and spider web) and now it has been cleaned up. Here a few pictures, MX400/Trex450 Hybrid will start spying California sky again very soon! It has more yellow parts on it now and I have cleaned up the canopy for the stickers. I thought I would wait until HeliTown stickers arrived from the UK, but can’t wait. I will get more pictures with HeliTown stickers when they get here.

I still have the gyro at the tail boom, as when I tried to move it down to the frame, my tail does not hold up any more. I’ll figure later, but for now it is there as I don’t do any fancy flights.

Great job Eddie! I was really getting worried. If you were to show up to the fun fly with Thahn and I with a CX.. Well that vid would have had to be a presentation. :lol:

Sure feels good to get them back straight don't it.

Steve

Steve

Yes Steve - me too. I have to really work hard to get to the same level as yours and Thanh's. I really start all over again now. But, I promise I will not show up with a CX :) but a camera and a camcorder. :) By the way, I just checked with my nephew and his graduation is not until 2007 Fall. I don't like to go there in a Fall but we'll see what we can do.

[eddiemoth]

OK Since cmaxim picked her training gear today for Trex450 and she is going to take my Trex450, I picked up an MX400 CCPM Conversion kit. I hope I can make my MX400 fly the same as my Trex450. Here is the picture of the MX400 CCPM conversion kit.

One CCPM swashplate, three push rods and linkages, the top frames and the top dome (you don't need a top dome to make it a CCPM) but it is in the package.

http://www.rchelicoptertown.com/forum/photoplog/file.php?n=96&w=l

[eddiemoth]

Hi Steve or anybody has a CCPM MX or ARK400,
Do you still have your CCPM MX400? If yes, can you confirm the servo positions for me? Please see pictures below. Sorry of out of focus pictures. I am using Fut S3017.
Thanks
Eddie

[estarter]

Nice MX400 CCPM conversion, I'd like to know the flying/handling difference between the HDE and CDE.

[swatson144]

Looks pretty close Eddie but the elevator (rear) servo arm needs to be inside the frames.

Steve

[eddiemoth]

Thanks Steve for the pictures. I'll change my rear servo position.

Hi estarter, yes I'll share the experience!

While waiting for the servo position confirmation, I put the head together with the CCPM swashplate.

http://www.rchelicoptertown.com/forum/photoplog/file.php?n=100&w=l

[swatson144]

All this X400 talk made me run a couple packs through mine.

Regarding the difference between MM and CCPM there was NADA as far as I could tell. That is assuming the elevator linkage and arm was replaced with CNC parts (or at least glued solid). If running on the sloppy stock elevator links it would be night and day. You could actually control the pitch of the heli and it wouldn't pitch for' or aft on pulling collective.

Steve

[Ranger]

I bet it wasn't as bad as my raptor crash Eddie, but I feel for you just the same, I know how it feels.

[eddiemoth]

I was finished setting up the CCMP yesterday and I am having some problems. I don't get enough pitch for both negative and positive because the servo horns are not long enough. I am using Fut S3107 which is not an ideal servo for a mini and tail. We'll pick up a better servo for the tail today.

Also I have angle problem as estarter pointed out yesterday. Another issue is the canopy touches the pitch and aileron push rods which I need to fix.

[swatson144]

I'm still using S3110 on cyclic, and S3153 digi on the tail. The S3110 actually came with decent arms. The 3107/08 arms are a joke if I remember right. You can use Hitec hs50/55 arms if I'm not mistaken on micro futabas at least they fit the 3110s which I tried in the BPE. If I were to build one up today I'd go with the HS-65HB on cyclic and S3153/gy401 on the tail.

Steve

[eddiemoth]

You are right about the arm of 3107/08. With the old frame I had to lengthen the arm for the pitch servo. Since it is now CCPM, I can't cheat any more as I have to do on all three servos. I'll pick up these

http://www2.gpmd.com/image/f/futm2005.jpg

[eddiemoth]

I got the servo arms and everything seems to be perfect for the pitch and everything except one big thing which I can't figure out and I need help. When I use the rudder for either side right or left the helicopter turns violently. I use GY240 and S3107. I used both AVCS mode and manual. I know S3107 isn't perfect for the tail but it was kind of OK before I converted. So there must be something wrong that I did but I can't figure. So does anybody have any clue?

[swatson144]

When I use the rudder for either side right or left the helicopter turns violently And the problem would be? I've spent good money getting a tail to react violently!:razz:

I'm assuming the gyro is not rev/fwd the wrong direction? you'd give a little yaw input and the gyro would detect as wrong direction and input to stop which makes it worse and so on.

you can use EP on the rudder chan to tune down the yaw rate if it's just too fast (don't sound like it).

On further consideration I don't know what has changed with your rudder setup. If it was working well as a MM it should work the same as a CCPM, unless you changed something in the tail. I'd just go back to basics and make sure the rudder servo moves the correct direction and the gyro compensates by moving the servo in the correct direction.

Steve

[eddiemoth]

Steve - you are still my guru since a year and a half ago when I set up it the first time and now. You know what? lol I didn't turn the REV switch on the gyro all the way because I need glasses 6 months ago and I still have not had time to get them because the hobby takes the priority. It is working now after the REV/NOR switch was turned on all the way.

[swatson144]

It's usually the simple stuff. Fortunately I'm simple enough to point it out.:D

I don't need no glasses I got these implants!

Steve

[eddiemoth]

I am now on my way to get a pair of them. lol.

[helitaiwan963]

Hey guys. I've been flyig the king2 and i'm got FF down. My Mx450 is getting shipped on Friday. Got HS55's on swash and HS81 on the tail with the servo mounted on the boom. I still need batts and comp tx to get this thing running. Does anyone here have a old 7CHP or 9CHP that they would like to sell cheap?
Also, is there anything i should look for as with common problems you guys ahve been having?

Thanks
Eric

[swatson144]

1st thing is the spur gear is smaller than a trex so don't duplicate any trex owners setup with out taking that into consideration. I suspect this is the single biggest problem with the few reports of shedding parts mid air tail blades etc.

If it's a mechanical mix then the elevator lever needs some attention most likely. Hold the swash and wiggle it for and aft odds are good you'll see a lot of slop in the lever and arm junction.

Many claim you should change the tail blades for trex 450 blades, 3$ why not but I've run the stock blades also.

If it hasn't been stretched that's a "do it next crash" thing. Trex 450 (XL and newer) boom and belt works fine for strech. That alows you to replace the cheasy blades you just trashed with some of the more popular 315-335mm blades.

Great helis!

Steve

[helitaiwan963]

is there anything wrong with the tail? I've hard cases that the tail on the mx450 sucks.


Thanks
Eric

[swatson144]

I just got on the same page here the MX-450 is a upgraded mx400, kinda like a trex 450SE. (and sporting more metal than my X400 is wearing)

Naw I don't think you'll find anything about the MX450 that sucks. One might be able to pick nits over some of the design points and come to a conclusion that it sucks but the heli won't know it in flight. ;) I had a pair of X400s one stock MM, one upgraded ccpm with some metal and a Micro Heli Pro V2 tail. Even the stock plastic tail worked great (still have the later).

I think you'll like your new heli. Nothing substandard or "bargain" about it. Designed by the same guy who designed the trex 450, after the trex 450. If helimax jumped on the Lichann design a couple months earlier the places would be swapped, and thousands of X400 owners would be saying how much trexes suck.lol Just my opinion but either could have won out as easy as the other.

Steve

[eddiemoth]

MX400 is back in the air! Now since I get used to GY401 and S9650 tail set up, GY240 and S3107 are not really great any more but they are OK.

http://www.rchelicoptertown.com/forum/photoplog/file.php?n=157&w=l

I still have the gyro on the tail boom. I tried to place it on the frame but it was jittering to much that I had to move it back to the boom. I'll try to move the ESC to the front and try to place the gyro to the bottom again.

Eric, I am glad you are joining the MX400 owner club! I think MX450 has all you need. It comes with eCCPM so you don't have to do what I am doing now. I wouldn't say it is the same as Trex450 SE but it is a decent helicopter with that price. Mine, I replaced the tail with Trex450 SE because the stock tail on MX400 was weak. So my MX400 is 40% Trex450 and 60%MX400. I don't have any problems with it.

Eric,

Nice pics.

Wow, the list price is $599.99, I hope you didn't pay $249.99 from the Hobby town USA. I heard from other members that you can get it from Tower hobby for ~$69 with the discount and free shipping coupons.

[helitaiwan963]

69 bucks? i doubt it. That's probably the Mx400 version. But no, I got this heli in a trade for my RTR nitro rc boat. Also. Update on the tx. I ordered a 9CHP yesterday night and i should have it by this weekend:)


Later
Eric

[eddiemoth]

Eric, it is very nice. I like the new Heli Max canopy. So it looks like the only thing you need is the TX and then you are ready to rock it in the sky. So what is the gyro and tail servo you are going to use?

[helitaiwan963]

Yea, I got the tx in already. Flew it a few times. Then...glitch then PCM lockout on me:*( Broke CF tail boom, fins, bent frame, skids are done,flybar,mainshaft,spindle,tail shaft,main gear...SUCKS SO BAD!! I didn't even get to fly it for real yet, only hovering on the driveway:( I still need flybar, mainshaft and lower main frame...:(

I used a HS55 on the tail, but i just got my JR tail servo in with the uH tail servo mounts but i haven't gotten a chance to touch them yet...:( I have the align 500 gyro on it. Anyone got a speical little contraption you can teach me to make so i can use trex skids? cus i have a set of trex skids but no mx450 skids, or if anyone wants to send me a mx450 skid for a Trex skid...



Later
Eric

[eddiemoth]

You sounded like a big crash. To use Trex450 skids you need Tedani Alum mounts. I could find them on their website any more and not sure if they still sell them.

[swatson144]

My buddy is firing up his X400. He still has the mechanical mix and I keep saying that the MM is as good as the CM on this heli except you need to address the factory slop in the elevator arm and elevator torque arm. On mine I bought CNC elevator parts. Left stock the slop makes the heli very unenjoyable to fly as adding collective will change the elevator. The friction in the slop makes it random. IMO this is a must do on the MM X400 When one starts looking the $ for the 2 parts is a big portion of the CCPM upgrade.... So what's quick and easy??

Well a beer can shim! If you are still running the unmodified plastic ele parts, hold the elevator torque lever with one hand and reach between the frames with the other. Move the elevator lever up and down and you will feel slop!

Simply remove the torque lever.

Cut a sliver of beverage can that is the same width as the flat part of the elevator torque lever hole. Leave it as a longish strip so you can handle it. I just used scissors. Take your time and get it right as there is plenty stock on hand ;). Oh DUH! the strip will be sharp.

Stick the strip in the hole. Just let it stick out a couple MM on the back side is fine. That will make it easier to get the lever in place.

Slide the shim and torque lever onto the male part and the extra will be pushed flush in back by the frame bearing.

Insert the screw and washer which will fold the shim over. cut off the excess and file so it don't bite you later.

Below is a pic of the torque lever I modified to test. The slop is gone! This one was done off the heli and the shim was glued. The glue was just to make it easy for Rick to remove from this elevator lever and put it on his (still on the heli). If you are doing yours on the heli I see no reason for glue.

Steve

[swatson144]

I had the X400, with the Ark head on it, out in the wind today. Tried out 3S A123 on it. 245g with wires 2300mAH. I think it'd be a real winner for a scale body! wouldn't even have to remove it to charge. 3500kv motor with 13T allowed me to turn the gov up a little to get the HS up from the lower voltage. plenty of pop. The LVC was still set for 3S lipo and kicked in at 5.5 mins I'm expecting about 10 when setup right.

I'll need a calmer day and better setup on the 2100T I stuck in it with out doing any real adjusting.

Steve

[ranger306ci]

My hmax x450 is still in its box.
This weekend I am building a new workstation, and now that snow is on the ground..............I have time to build it! ( and put the copterx head on the king 2............ and replace the tail boom on the compy........... and fix my other moth.......... and install my new nitro engine on my truggy)
Right now, I have one heli, a moth, that is flyable. Wait, can i count the 4 picco z's that I fly every night?:D

[Sonex128]

Where is the best place to buy MX400 parts? I put a Trex head and tail on one I got cheap. Looking for a place to get gears in case I would need them.

[swatson144]

Tower is about as good as any. Seems the norm is gear set with 1way ~9$. I had a line on a fellow that sold ARK parts and they were about half price without helimax's markup, but he quite selling.

Steve

[Sonex128]

Thanks Steve. I haven't found a main gear anywhere but Tower.

[skypup]

I've been flying helis for 12 years now and have never had any real luck with medium helis like the 400. I test flew my mx400 today and had a unique experience. I have 1.5 degrees negative,6.5 hover and plus 8 top. I have an align 430L (3550 kv) motor and a 10t pinion. I am using a gy240 gyro in rate mode to trim my heli. I set my stunt throttle at 75% all across. I started my spool up with the stick and then hit idle up. The motor ramped up and the heli started to rise with the tail stable. Problem was, at bottom collective the heli continued to rise. I killed idle up and the heli hit the ground on its training gear. I broke the head and a link. The blades were fine. I have the MX450 on the way and I ordered some metal for the head of the 400.

What am I doing wrong? Obviously I need more negative. What pitch do you hover with this machine? Thanks for the help.

[Sonex128]

What is your idle up pitch curve set to? It is different than your normal pitch curve. What radio are you running?

[skypup]

I finally got her flying and it is very stable. I need a little more right trim but the tail is at its physical limit. Any ideas?

[swatson144]

I'd move the stick in the direction it's trimmed and adjust the linkage to move the tail's control arm the same way and distance. center the trim and try again. If it's close switch to rate mode and adjust until it hovers with no stick.

When I was running the stock tail I actually moved the TR hub out a little on the shaft to get more equal piro rates.

Steve

[ranger306ci]

Well, finally got mine built, and ready for flight testing!
The parts are:
align esc and 3550 motor.
hs65's on head, hs65mg tail
logitec gyro
hexatronic bec
spectrum 6100 rx
fiberglass canopy rc-tec sent free!
Now, just waiting 'till spring to take her out.
I am going to use align blades when they come in. Right now, she is wearing my b400 blades.

[estarter]

Very nice, please post the flight report.

[swatson144]

It looks like you have Align paddles on it? If so it'll be pretty quick, and with the long align flybar crazy quick.


Steve

[ranger306ci]

Those are now gone as of last night. I needed a flybar and paddles get the head set up, and my mx450 ones were on the b400.
My new parts came in last night, and now it is weaaring the proper gear.
Got my align blades in, to. Just waiting for extra fs to come in the mail, and i will have all my consumables in order!
One thing I don't like about the mx450 flybar setup, is the fact that the paddles are held on by setscrews only. I poured some threadlock on the hole to give me extra holding power. although, with centrifugal force, I am not sure how much good that would do.
Are the setscrews adequate to hold the paddles>

[swatson144]

The setscrews are more than adequate. Any brand of FB and they bite into it providing a very secure hold.

Steve

[ranger306ci]

What are your swash settings at? I have aleron and elevator at 65%, and pitch at 90%.Gives me +/-11 degree and a fair amount of swash movement for cyclic.

[swatson144]

That would depend on which one I looked at (I have 2). It varies by servo and arm length etc. I just set swash AFR to the max non binding and use limits from there to tune what I want it to feel like, which is usually max.

With the over driven (stock) tail I like about 2700 rpm on the head. Higher costs power and isn't that great an improvement, lower costs performance and doesn't improve flight times much. 2700 seems the sweet spot.

Steve

[ranger306ci]

Alrighty! I don't remember the pinion I have one, will have to check that out.
My esc has a gov mode, but I seem to remember that people didn't like it. Do you recall? (align 35amp, older model, "H" I think)

[estarter]

Have you flown the MX450? What's the difference (flying/control) between Trex 450, Blade 400 and King2?

My BlackHawk 400, a ccpm version of the Shogun v2 flys similar the the Trex, I can feel she is kind of lighter than the Trex and heavier than the K2.

[ranger306ci]

Have not flown yet. Weather is kinda iffy here, and still need to mech set the tail. Hoping to this weekend. Just been sneaking in flights with the fps right now.

[estarter]

Been windy in the west coast, only limit to do some hovering in my neighbor's front yard in the late evening. He set up flood light and its as bright as daylight.

The X400 is pretty much a 450X mechanical mix, The MX450 is pretty much a XL, (stretched 400) somewhere in there same as on align the CCPM starts showing up. All things being equal the X400 series has a smaller main gear by 10 teeth and a higher tail ratio 1:5.

The Ark/helimax head is a little faster but slowed by integral weights on the paddles and short unthreaded flybar. It was designed by the same guy who designed the Trex450X after the trex and very very similar.

Both of my X400s are really CCPM X450s. One is wearing a copterX head and the other an Ark head with some CNC parts. In a nut shell the x400 series was not made for (what some of us think) excessive 3K+ head speeds but seems to be fine pushing 3K (mainly because of the high speed tail gearing).

In a nut shell the x450 and trex can overlap in performance and even in "feel" with minor changes to either like paddle weight, flybar length, HS etc.

Well, I finally flew my MX450 last night. It is soooo stable! This is the heli for me and my meat thumbs!
I basicly hovered for 6 minutes, just letting things spin to look for any problems. Only thing I noticed was my tail slowly moving to the left( tail in) in hh mode.
So, a little adjustment is needed. Blades need a little tracking, too.
All in all, I love it.
Motor was quite warm when I was done, probably due to running 6 minutes at less than 75% throttle.
My batt was at 3.97 all cells when I was done. This is the 450 for me!

It's a neat machine and I seem to keep 2 of them around. I really like them.

Well, found one of my aligns was warped out of the box, so I put some carbon fiber blades on. This thing is MUCH faster responding! Might go back to woodies for now.
