Well, considering the Solitaire motorglider, his last contribution to
the world of soaring, I'd have to entertain some doubts.

Not that I don't think he could, as you say, make terrific sailplanes.
Just that I don't think he'd be inclined to play the incremental game
of quarter-percentages that modern sailplane development seems to have
become.
