I am building a 1/4 clipped wing Cub and thinking about going with a 26cc gas engine. Would this be appropriate. I have never used gas before. I have looked at the 26cc and the 45cc. Not much difference in price. The 45 says it swings a 20-22" prop. Seems kinda big. I have a Mag 180 4s that I use a 16/8.
