Building a Dynaflite Super Decathlon and wonder which is the engine of choice. Want to go gas... but don't want to break the bank on a engine. Any thoughts will be appreciated

I have looked at this plane often, and If I had on, I would use a Zenoah G-26. It would be perfect. I have a G-26 and it is an excellent engine.

I got to fly that plane with the G-26 and it flew very well but the owner went to the G-38 and it flew A lot better. Just depends on how much stunt flying you like to do. We now have some great choices in gas engines on the lower price list. Go take A look at the gas engine thread and see what has been going on.
