RE: pane for .40LA
My friend has a low wing Sonic made by Phoenix. It is considerably under $100 (from Tower) and is an excellent flyer. Although the plane is for, I think, a 25 engine, the 40 LA is a light engine, and a mild engine. This combo turns the engine into a real performer and he has had the plane for a long time. Think you would be happy with this combination. Good luck.
