Hi Crash - I had one of these planes before and powered it with an OS Max FP .25 and most of the time flew 1/2 throttle. I'd have to agree with others on this thread that you are a little overpowered. However, if you read some of the other threads on this plane, there are folks who have stuck a .46 on the front - why - I don't know - guess they just feel the need for speed. It is a great plane that will hold your interest past being a trainer. Wish I still had mine.
