hi there.....have a belt-cp.....totaly stock which has flown great up to now.....but now the esc is heating up and of course the copter is dropping from the sky after a couple of minutes.....everything is free and oiled and dont feel as if the machine is under excessive load.....
that in itself doesnt bother me too much as a new esc is on order.....the main problem i have is that after connecting a fresh battery the gyro does not set itself......removed the gyro from the equation and plugged the tail servo directly into the receiver.......the tail servo works fine....faulty gyro !.......ordered another gyro (stock again) fitted and have exactly the same problem not setting so no tail......receiver and servo are obviously ok so have i just been unlucky and received a faulty gyro?........the esc fault shouldnt be connected.....or is it......any help offered would be appreciated

thanks
