preformance differences between edge, extra, cap, sukoi ?
Extra- Tend to be very stable, chosen most for pattern aerobatics, 3D with the right tail design.
Cap- Stable, a bit more sensitive, very good for tumbling maneuvers & 3D.
Edge- Very sensitive(think move thumb and plane reacts), Good tumbling, good 3D.
Giles- not good for much.
Sukhoi- not a clue, but a friend does great precision pattern with his.
