SaCCal72\\If you are going to be building a kit and want a very nice flying plane try the Sig 4 Star 120. I know a couple of guy's flying on of these with a Ryobi 31cc and they fly great even with the magneto still on the engine. It would be even better if you convert to gas/glow fuel and loss that extra weight. I plan on building the Tiger Moth that being sold by Nitroplanes. Take a look at this. It is an arf and does cost a little more, but this is a great looking plane and Av8tor is building one right now with a Ryobi 31cc gas/glow engine.
