I have a Trainer a Right Flyer 40 (for 40-52 engines) 63" span , The engine on the plane a .46 magnum is in bad shape and needs to be replaced, I have a brand new KB sporter .65 and would like to use it on my trainer, some guys at the field say it's a good move, while others say it's too much power, what should I do?. I've been flying Solo for the last 6 months Thanks David
