My thing really has been building, I am moving into more scale planes now with the 1/4 scale Chipmunk project about 90% build (covering is another matter). I have learned how to fiberglass and paint ect. The whole engine thing was fairly new to me, the good news is I have a bunch of engines that need airplanes, the bad news is I have 7 airplanes now and one wife, I believe an 8th airplane may upset the whole equasion
