<span style="font-family: Comic Sans MS;">I have an ASP .61 2 stroke engine on a showtime 50.When I start the engine I dont have any problems at all.When I raise the airplane fully noise up to do some 3D aerobatics the engine is suffering from a stalling problem.The engine stops TOTALLY and last 3D aerobatics I was going up for a 3D torque roll and the engine stopped and crashed causing no airspeed at all.Now I fixed the airplane as I had some minor cracks in the wings because of the landing gear.I started off the engine and the problem is still there.Could you please help me?






Thanks Clayton Vella
