Flew the G11 rokkaku kite on the runway today. The G11 kite has the same strut-spar connection design as the G9 and G10 kites, but the G11 is 25% smaller overall, and its tubes are made of Dacron, not cuben fiber. The kite flew stably but had a tendency to steer in one direction, which is a problem that many of the earlier roks had. We may be able to solve with bridle readjustments, however.
