king_arthur1953,

I have had two of the Brillelli 26cc engines and the 40cc engine. Very nice and powerful engines and Scott at Brillelli will bend over backwards to help you in any way he can. I also had a Zenoah G62 that I sent to Ralph Cunningham at RCIGNITIONS and had him convert it to IE and cut some of the weight off. Ralph is the man to go to if you want a gasser worked on or buy one that he is selling. I don't think you can go wrong with either one.
