Hi all,
My girlfriend's dad picked me up this heli: http://www.hobbytron.com/SkyTrooper...Helicopter.html

for a random little gift.

It has been a ridiculously awesome blast to fly around! I had no idea these little toys could be so stress free (and freaking funny imo) to fly around.

However, a few days ago I hit the wall and crashed. Nothing looks broken to me but I am having an odd power problem.

The heli works well for 20-30 seconds and then its almost like the power is cut by 20-30%. The sound of the motor changes - although what I probably hear is the sound of the pinion interacting with the gears or something. Anyway, the point is, after 20 seconds of flying, there is an audible change in the sound of the machine, the power drops, and the heli cannot be flown.

I haven't opened it up yet to poke around, but I'm getting close to that point. Does anyone have any suggestions? Thanks in advance.

Open it up, might have a hair wrapped around a shaft or pinion gear.

+1 for Flyer but it most likely has a crappy battery.

They are fun to buzz around with.

Okay, today I'll bite the bullet and get in there and poke around.

Its funny though... the pitch (sound) of the heli increases dramatically when it goes from "flyable" to "not flyable." Makes me think something is slipping and thus allowing the motor to increase RPM.

I will open it up - if anyone else has any suggestions let me know. Thanks much.

You may be on to something if like you say the sound of it changes. Good luck, hope you find the problem. Those little heli's are a blast in the house.

I agree about the sound change being meaningful - I mean it obviously must be, right? It goes from sounding normal and flying well to a higher pitch and not enough power to stay in the air...

For anyone curious (who might have a similar problem crop up in the future) the pinion of one of the motors had cracked during the crash. I used some threadlocker to secure the top of the pinion (it wasn't cracked all the way through) to the main gear and that seems to have fixed the problem for now. Two successful flights down - these birds are obviously not made to last forever, so if some threadlocker gives me another couple flights before the pinion cracks all the way through it will have been worth it.

Glad you found your problem. Hope the fix lasts a while.
