i have heard the a 50cc class plane flys much better than a 40cc class plane. I have a 44cc stihl engine with CH ignition and i am looking for a plane to put it in. I really like the Edge 540. I am starting to do some 3d stuff with my smaller planes so i want to keep that in mind when shopping for a bigger plane. My engine turns a topflight Power point 20*6-10 at about 7K. Any suggestions??
