RE: Electric SPA plane
I wish that I could tell you I have tried it, Skip, but all I have been doing is thinking about it. However, it could be a lot of fun, I'll bet.
One would probably be better off just buying a foam wing kit and then a set of plans so that the scale outline could be maintained for the new fuselage that will have to be designed. I'm not saying that a stock fuselage couldn't be converted, but by the time one is done with accomodating the batteries in the proper location for best balance, a redesign just might be simpler.
I'm just an old windbag in electrics without much experience.
