I recently came by a Rearwin Speedster, This plane was scratched built. It has a 76.5 wingspan and is powerd by an OS 120 4 stroke. Weighs about 11.5 lbs. I just love how scale it flys. Easy to take off and land. I noticed that there is an ARF available that requires a gas engine. I bet it would be a blast to own. Just do a web search on the Rearwin and check out the history on it
