Yeah, I've seen both of those...as you say, however, they are first the "wrong" scale (wrong in the sense that, imo at least, to do this all 3 planes should be the same size) and second, they are sport scale...though, I suppose one could certainly do the work to spiff them up.

Of course, I'm merely hung up on 1/3rd scale since I have the Bulldog started...I guess there's no real reason they couldn't all be, say, 1/5th scale...would just mean I'd have to build another Bulldog
