when i was playing with my RC Helicopter it fell and it couldn't rise anymore it just spins in circles... the module type is Vision SO10 mini 3... pls help!


Answer
In a coaxial copter like yours, the tail rotor serves to pitch the copter to go forwards or backwards. The coaxial blades spin in opposite directions to counter act the spin force that a tail rotor would otherwise handle.

What this means for you is that one set of blades is spinning faster than the other, causing the bird to spin around. If you have a trim adjustment on the throttle stick, you can use it to make one motor spin faster than the other. Or, to balance them out rather.

My Mini rc helicopter was working fine until now, now when i fly it, it turns to the left and spins......?




TCB1468


so i tried adjusting the trim to the right but it has no display of where it is adjusted to it just has 2 buttons (left and right).The trim really hasnt made a difference either. please help


Answer
It's a good idea to use trim and co-ordinate your turns, and in general this should solve the problem. If, however, the problem persists, then I would guess that you would'veve thrown the tail rotor assembly out of whack. This may be the angle of the blades being improperly balanced, or a faulty motor, or something else. I would recommend that you take it to your nearest hobby shop to have it checked out. Above all, though, remember that a helo is not particularly stable and to fly it properly may be as simple as taking a few hours of time aside for some good, old-fashioned practice. Try and make your movements small, but direct and very, very precise. It's a skill that has to be honed very accurately.
