Bruce,
Sounds good to me. I am in the process of building a swept flying wing pusher, I plan to either put a Homey 25 or a Ryobi 31 on the back of it, depending on how big I go. I would suggest going to electronic ignition to get rid of all the weight you can since the engine is probably going to be behind the CG a ways. That's what I am going to do anyway. Good luck keep me posted how your doing, I'm interested in unusual projects. Ron
