Well I finished the little rascal last night. When I got home from work tonight I gassed it up and decided to break in the engine. Man! Thant little Wankel is going to make this plane a rocket and an acrobatic fool! Sounds like a hornets nest at full throttle and amazingly enough transitions very smoothly. I drove it around the yard for two tanks of gas and I can tell you it has a ton of power for this plane. Holding it up I'm guessing I could hand launch it vertically at about 2/3 throttle. OS recommends a 9-6 for a break in prop so that is what is on the plane right now. I don't have a tach so I can't say what kind of RPM it's turning but judging by the sound it must be 16K or more. Once it breaks in it should swing a 10-6 just fine.
