I was wondering what would be the best engine for the Sig 1/4 scale Cub. Would the Ryobi 31cc engine fit well in this plane? I was looking at the Zenoah G-26, but decided to go the conversion route for the cost. I have a lathe and mill, so I can make most of my parts. One other thing, is there anyone selling CD ignitions for these engines, and if there are, roughly how much do they cost?

Thanks.
