Default Need help with micro twister helicopter

Hi, i'm a beginner to rc helicopters and new to this forum.

i am not sure if i am in the right place on the forum for this but i am having problems with my rc helicopter.

I have had the rc micro Twister helicopter for about 3 weeks and was getting good at flying and landing and not crashing.

I fully charged my heli the other day turned it on went to fly it but for some reason it wouldn't take off so changed the batteries in the controller and charged it again thinking maybe the batteries was dead.

Left it to charge and then turned it on and tried again but this time the bottom blades wouldn't spin at all. I don't want to throw it away cause its a nice heli for a cheap thing.

Anyone know what the problem could be and is there away to fix it?

Looking at pictures of it, it could be something as simple as the motor pinion gear isn't engaging the spur gear on the shaft for the lower blades.

I've had it happen on a couple of the Blades I've had.

As for the original problem, could be something as simple as a bad pack.

You may find more help if you post down in the heli section.

When I die, I want to go like my Grandfather did, in his sleep...... Not screaming like the passengers in his plane.

"You may find more help if you post down in the heli section."

I agree, most of us here are not heli types. I, for one, am clueless.

I am going to move this to the Heli forum where you should get better answers.

Check for hair or fuzz or other foreign matter wrapped around shafts and gears. If you fly inside this is likley the issue.
If all that seems clear and the one rotor turns then you know it's not the battery. So can you hear the motor trying to turn the blades ? On coax heli's there are two motors, one for each rotor. If it is then something jammed. If you hear it running (both motors) but only one rotor is turning then something is disconnected in the drive train, stripped a gear, etc. If only one motor is doing anything you can swap motor leads and see what happens- if the same motor turns as before then the one motor is bad or the problem is in the gearing/shaft for that motor. If the 'bad' motor' now turns the 'good' one doesn't then it's your controler that is bad.
