RE: has anyone done this ?????
Magnum, a few suggestions,
I've done a few conversions myself, and find them to fly decent if built light. you picked a good airframe, high wing, light, and admirable wing area. My conversions include the p-51 and spitfire guillows kits of the same scale. For you though, get rid of the satellite antenna. you will not be flying far enough away to need it, and it is dead weight. also, you can cut the reciever weight in half by removing the plastic case, and using heat shrink tube to cover the reciever. just those two mods will save quite a bit of weight. Your build looks great though! I look forward to seeing some in flight pics!
