I am looking for a gas engine that has the same specs almost as a saitio 220. I want to stay gas when I got to hangar 9 p-47. I have a zenoha engine in my boat in runs good. I don't know in an airplane. I have had a fuji, along time ago, din't like it at all. I don't to many good 23cc-30cc gas engines that arnt to heavy. But if I cant find anything I guess Ill have to go with the saito 220.
