1. Since most current high performance gliders carry their laminar flow
across the aileron gap, the drag penalty of a deflected frise aileron,
compared to the deflected rudder, would be huge.

2. Peterson J-4 Javelin - see later posts for more details.

3. Fox has NICE ailerons, for acro - I always had an irristible urge
to do slow rolls on tow when flying a Fox. Also real nice aileron
snatch at the accelerated stall break. It doesn't fly like a racing
glider, it flies like a little fighter plane.
