Yes, I was thinking small. Depron, electric, etc.. But for me, if I couldn't reverse it in flight without reconfiguring the plane I don't think I'd have much fun with it. I had considered using one of those 4D variable pitch props that we see on Flatouts and ShockFlyers. Stability and C of G is one of those "other things to consider" that I have no solutions for at this time. I figured if a canard can fly 'tail' first, then it shouldn't be too hard to make it fly backwards. A normal aft mounted tail doesn't like going backwards. A friend suggested a tandem wing layout with no tail surfaces. I wonder.....?

Something else just hit me, can a canard fly inverted? Sustained negative 'G'? I never thought about that before. If so, it might be a starting point.
