ok I have a moment!
first of all, what kinda plane are you looking for! high wing trainer, cub style, low wing sport plane like cherokee!
aerobatic, arf, or kit!
at this size (.10) your gonna hafta start thinking out the box! most planes nowadays, under .40 size, are designed to be electric powerd!
if you are able to do a lil modifacation, then get a elctric powerd plane, and convert it to work with your engine!
