I HAVE A 40 CLASS HIGH WING TRAINER, IT SEEMS TO BE GROSSLY UNDERPOWERED ON TAKEOFF. Do you think it is worth the money and the trouble of changing the engine to a .46 size that I could later put in whatever I build? Secondly which is better of the 3 engines I am looking at the Thunder Tiger .46, the evolution .46, or my choice the OS.46AX? Any help would be appreciated and thanks in advance for all responses.
