I ended up picking up one of these at D&J's because it was on sale. I'm not sure it was the right choice, since I was looking for something that could handle a little breeze outside, since my apartment living room is kinda small. Looks like I'm gonna have to wait for real calm days.

Thanks to the instructions here I got the training gear mounted, but I'm concerned, the flybar paddles are tilted even with the helicopter at neutral. Do I need to adjust something?

[swatson144]

Looking at the end of the paddle both paddles should be in line with the flybar carrier/yoke/oval thingy the flybar passes through. Or with the swash level the paddles and main shaft make a perfect +

Wow this must be the shortest model owners thread on the whole site :0

I am getting a nightranger 2 secondhand to muck around with. I believe that the battery pack is a 5 cell probably NiCd (maybe NiMH but doubt it.)
Therefore 6V I guess? (5 x 1.2V)

Can I use my 7.4V Blade CX2 packs if I change the plug over?

[broggyr]

Mark:

If you are getting a Venom Night Ranger II, then I think it's a clone of (or has been cloned by) the Walkera Dragonfly 4, Exceed-RC Falcon 40, E-Sky Honey Bee FP, and others.

I have the Falcon 40 - the heli came with a 7-cell, 8.4v NiMH battery. I use 7.4v LiPo in it all the time, and it is even heavier than normal due to all the stuff I have on it (separate radio components, speed controls for motors, brushless main, etc)

[Mark _australia]

Cool. Hey I will get a proper medium sized chopper like a Blade400 or Trex450 soon but is a way off (the financial controller is upset at me, her birthday soon and all) so I'll play with the Venom Nightranger a while. I have heard the tails are hard to control (yaw) on these little ones with tail motors.
Are they that bad (I'll fly indoors 90% of the time so wind is no concern)
Can I fit a heading hold gyro ro a Venom Nightranger?

[broggyr]

You *can* but you would likely need to use a new radio system - the current gyro is built into the 4-in-1 along with the Rx and integrated speed controllers. Because the tail has a separate motor instead of a servo, it will tend to have a mind of it's own.

On my setup, I replaced the OEM radio with a Walkera 7-ch Tx/Rx set (cheapie from eBay) because I was having massive glitch/interference issues. I am using an E-Sky rate gyro (the stock one that comes with the Honey Bee King II, etc). I had to install a separate ESC for the tail motor, and when I start a flight, I have to "arm" the tail ESC by pushing the rudder full-left (the ESC must see this as a throttle, and has a throttle-safety setting) or by 'yawing' the bird with my hand, but this gets the tail going too early. All in all, each ESC has to be managed on it's own until you get airborne, when flight becomes more like normal.

These hels do NOT like breezes (forget about wind) - I am sure some veterans will have no problems, but for myself, I have enough to do keeping a stable hover in a draft-free environment.

[estarter]

I have good luck with the W#4 and W#22e radio, had 100+ flights on them and no glitches. I believe the 22e is kind of like PCM and is very reliable, I did burnt up the 22e esc when flying in wet weather but has been repair.

Hi all
I have recently started to try more than bunny hops with my nr2. It appears not to have enough power to get more than a couple of feet off the ground. I've checked the charge voltage of the battery, alignment of the blades etc. The only non standard mod is a bike spoke fly bar. Mine is also difficult to control but the only heli I have flown is a co ax e sky dauphin so it could be my lack of ability. Is there anything else I should check to get more altitude from the nr2
Dmoo

[broggyr]

First things I would check would be the gear mesh, make sure it's not too tight. The pinion and main gear should move freely, but not have too much play. Some folks have adjusted this by loosening the motor screws, rolling a piece of paper between the meshed gears, and press the pinion close to the main gear while tightening the motor screws. When done, remove the paper - the gap should be correct. I haven't actually tried this, but maybe it's worth a shot.

Also, these helis have a decent chance of having a bad battery or motor. The first upgrade a lot of folks do is a lipo battery & charger, cost about $40 - a lipo battery can weigh almost 1/2 the weight of the OEM battery but still fly very efficiently.

[Dmoo]

HI,
Thanks for advice. Have adjusted gear mesh,was tight. Have also tried 7.4v 800mAh li-po,still not enough lift. Is possible li-po output not enough so will try a 1250 mAh battery and new motor when I can source them.
Dmoo

[estarter]

The FP like the NRII/W#4 should fly fine with 8-10C 2S 800mah lipo pack. Assumming your batt and motor is good, I would check the flybar paddles, you can have up to +5 degree pitch to get you more lift, you can twist the main blades clockwise to shape the blade, that also would get you more lift.

[Dmoo]

Thanks for the advice. Have twisted blades & adjusted paddles. Still same problem so its looking like a motor problem.
Dmoo

[broggyr]

Unfortunately, that's all-too-common with these helis. I hear many folks on another forum who have had great luck with Century motors as a replacement. I used a Slo-Max with great results myself.

[estarter]

Hard to diagnose problem without seeing the heli, I had over 5 hours flight time in my W#4 brush motor, the brush motor last for a lot of flights. I fly with 2S 800mah lipo pack with heat sink in the motors.

[Dmoo]

Fitted new motor and it didn't make a great deal of difference so in desperation I removed the decals from the blades. This seemed to improve the performance significantly. Heli now will gain height to about 8 feet before I chicken out so problem appears to be fixed. Thanks all.

[broggyr]

Interesting... Glad you found a solution. Happy flying!

[estarter]

My W#4 blades have no decals, just plain plastic.

[Dmoo]

Have just ordered some W#4 blades after a extra heavy landing destroyed one. Lost control of heli about 100 feet from me. Thought the range should be a bit further than this. Am I expecting too much.
Dmoo

[swatson144]

Range should be way farther than you can see it.

Are the ones you speak of the venom night ranger micro?
I was wanting to know more about this little heli.
What experience's, problems, etc.

no it sounds like to me you are thinking about a vnr3d micro which have cp

[FlyGuy]

Yes, I am looking for an indoor CP heli.
I thought this might be a good one.
I have frined that says he will take $100 for his.
But it needs the 4 in 1 which you can get on ebay for about $35

[stephen2406]

My NRII has spent a bit of time on the shelf due to me crashing it and waiting for money and time to repair it, now I can Hover quite well for about 30sec - 60sec and land without tipping it or breaking anything but My battery (NiMH that was supplied with it) no longer holds enough power to keep it in the air if more that a foot of the ground I think due to it not being charged for so long between flights. When I try to fly it around it doesn’t maintain power even if I level it with full throttle it will reduce height and even touch the ground before going back up. is this the battery or is there something ells I should be looking at.

[Skytrek]

Sure sounds like a battery issue. Nimh cells don't like long periods of time on the shelf. Not sure if you have a charger that can cycle the cells but that might help. You may just have to replace the pack but thats not a huge cost issue.

[stephen2406]

Hi
I have had my NRII for about 8 months now, I had allot of trouble at first couldn't even get it of the ground without crashing. I really thought that it was a big mistake getting it. But somehow I stuck with it waiting for spare parts practicing on a flight sim between repairs. I had to replace the swash plate and when I finally got the part I was very meticulous about putting it back together making sure the swash plate was as flat an level as I could possibly make it, then I connected the Battery and it got about 3in off the ground I got 2 new battery's and then a new motor and finally It flew I was able to hover it until the battery ran out of duce LOVED IT I'v had a great run with it for about 2 weeks and then I could Hadley get it off the ground again I thought it could not be the battery's as I now have 3 and they cant all be stuffed so it had to be the motor again so I changed it and it still I cant get it off the ground. is there something I'm missing I'm not that clued up on how to look after 800 nimh 8-4 Battery any advice on what I could try would be very much appreciated.

[FlyGuy]

Maybe check the pitch of the blades as you move them up and down.
If it is a CP heli, they should be the same pitch up and down.
So, if you have 11 degrees of up pitch at full, you should also have 11 degrees down pitch at full. That is about the only thing I can think of at this time, with the information I have. Hope it helps.

[swatson144]

Stephen, all the little FP birds are pretty simple. I'd start at the basics and make sure there is nothing wrapped around the MS etc. Blades tracking? Head snapped in level? Please look at it with a critical eye... everything should be night angles.

Steve

[mtpenguin]

how do you check the angles a night? They'd be pretty hard to see... lol

just kidding. Right angles.


B-)

[stephen2406]

Thanks for the reply it was the motor that was faulty I did get 2 new Battery's as well although having trouble now with them check my other post

[stephen2406]

Thank you but it is a Fixed pitch heli cant change the pitch

[FlyGuy]

What type of battery do you have for it?
Lipo? Nimh? Nicd? etc. and what voltage, & mAh?
Also what type of charger? etc.

[stephen2406]

Thank you all for your help I'v ran all the battery's flat and recharged them straight away they are working better now although not as good as I think they could be but I think just another couple of cycles I think they'll be right Thank you again for your help and I look Forward to learning more about this great new hobby of mine of RC Helicopters

[FlyGuy]

Thank you again for your help and I look Forward to learning more about this great new hobby of mine of RC Helicopters
That's where you are mistaken.
You may think it's a hobby now.
But, it is an addiction. ;)
