I have looked at the Zenoah but I didn't want to go the cheapest and it is the cheapest I have found. I'm not saying anything bad about Zenoah engines, I just don't want to cut any corners with this plane. I know that the YW-48 would be alot more power than I need but By being a twin would't it run smother than a single and as far as weight, it weighs less than a Zenoah G26. I figured I could always throttle back.
