another spinning madhawk 300
A question for Andy....or whoever can help. I recently bought a Madhawk 300 (Coast Guard) heli and while futzing with the transmitter, accidentally changed it to a wrong mode and the heli flew into a wall before I could shut it down. No visible damage to the main rotors or rotor head assembly or fuselage, but I did snap all the blades off the tail rotor. Replaced it and everything looks fine, but when I try to fly, the heli spins in a CCW direction and the tail rotor is noisier than I remember. What I'd like to know is - how do I go about diagnosing the problem logically. And what's the most likely cause of this knowing that a smack into a wall caused it. Seems to me it could be A) some part of the linkage in the tail rotor assembly, or B) gyro problem.
Given that the tail rotor seems to be noisier now, I'm leaning toward a mechanical problem in the tail linkage somewhere. I've disassembled as much of the tail as I could without removing the fuselage, and inspected the gears....everything looks OK and the gears all seem to mesh just fine. I've tried holding the tail rotor with my hand and rotating the main rotors manually, and Ican move the main rotors....actually, if feels the same whether I'm holding the tail rotor still or not...if that means anything.
So I'm just not quite sure how to logically pinpoint the source of the problem....anybody have any ideas/techniques? Anything I"m missing?
thanks in advance,
I took the thing apart, and saw that one end of a black wire going from one circuit board to the other in the receiver unit had broken off. Does anybody know where the other end of the wire needs to be attached? I've attached a photo...or at least tried to...
Or is that an antenna?
