Too late! Bought a FPE 2.4. Total weight with muff/ignition/prop bolt/back washer 52oz. Swings a 20x10 at 6800. I'll put a 20x8 on it and have fun. Like the look of the quality(full machined casing), every engine is ran at the factory, only small adjustments (if any) necessary out of box, and the fact that it's mostly made in the US of A. I realize it won't 3D a 15 or 16 pound plane other than at 3/4 throttle.. Mine will come in at about 13lbs ready to fly. I'll let you guys know how it goes. I'll send pics of the finished product.
