This is a question about powering a Tower Trainer 40. I am a relatively new pilot and have put a 46 OS on my tower trainer. Today was the second occasion when I took off straight full throttle. The plane was slowly rising to the left of the runway still at full throttle and it made a sharper turn to the left and came straight at me all at relatively slow speed. In other words it turned left on command upon liftoff but made that left turn into a U turn. and I dropped in into the ground as it was coming straight at me. One more experienced pilot suggested that the plane was overpowered and went into torque steer as he called it. His recommendation was to run an OS 40 instead of a 46. I like the power of a 46 but perhaps another possibility is to drop the throttle back upon takeoff until the plane stabilizes and then apply more throttle. Would appreciate comments from flyers who have experienced this issue. Thanks!
