RE: evolution .61 on a Kadet LT 40
way too much engine for that plane. It would fly it, but why? At what level are you? What do you want to do next? It might be time to move up to that second plane--maybe like a four star 60? That would be a good match for that motor. I've seen that motor fly--it's a screamer. It'll turn a 13 X 6 prop like there is no tomorrow. You'll pull that plane in half. Actually, the most probably outcome is loss of aircraft due to control surface flutter, leading to hinge failure etc, etc, etc. If it's 3d you like, get a twist--99 bucks and you can use all the servos/radio out of your trainer. You're set! Put a prop with 4 pitch at the most on that .61 and have a ball!
