I had to add a LOT of weight to the front of my plane. I always try to mount the engine as close to the plane as possible. I installed a OS FX 46. It runs excellent but I think it is a little under powered for the plane. I made 6 flights tonight beautifull weather. Had 4 flights yesterday. Runs great and on high rate it will do it all. I use flaps on landing and it makes it much easier to land. Had a little mishap last night and did some damage to the fuse but repair was very easy. had to add the MAUI sticker to cover damaged monokote.
