Hi Solo, The Flitecraft Airplane Co. was just 20 min. south of me in Baldwin Ks. I have built their Cardinal, Bonanza, Arrow and Extra 300 and several of our club members still have some of their parts around here. I built several of their Bonanza's with retracts, and they are really fast. When they were still in business, Gary Leonard JR. , a co-owner with his dad, would make special wings for me to accept retracts. If you strap the battery and the Rx down inside the door, you won't have any problems. You can also patch any cracks in the fuse by mixing Acetone with some of the plastic mtl. and kind of weld it together. They were great guys and excellent pilots.
