hi mark i know what your problem is with the heli its the gear set you need to split the frame and take out that gear and pulley shaft that contols the belt for the tail rotors that pulley sits in a pin on that shaft and it strips very easily you need to epoxy that side of the pulley and grind a notch for the pin and super glue that and you should be all set theres a reason why that heli sells for so little a price because its all plastic just remember you get what you pay for, i found that out too a lot of people are having trouble with that heli
