I just looked at the pile of garbage that used to be my big outdoor lama, and that gyro is completely different than what you need to do this. The BOL gyro mixes the throttle of the two main rotor motors to hold heading, you need a gyro designed for a conventional tail rotor equipped heli such as this: http://www.hobbyking.com/hobbyking/s...dProduct=10113 I may just pull the eflight gyro off my blade sr cause the heli is useless for anything other than taking up space/decoration.
