RE: New os 37 heli engine
i have a hawk pro that came with 2 engines a tt36 which was in the heli and a os 32sx heli after many and i repeat many hours of messing with the tt36 i am removing it rom the airframe and installing the os just can't get the darn tt36h pro to run consistant runs for awile get warmed up or low on fuel land and shut down and will not restart have turned on both the screws till i am blue in the face still would not run right
probably a good engine but hard to tune
