The flight of the vengeance is superb to the sabre, in both turbulent and smooth skies. Landing the vengeance required very little adjustment from my sabre technique. Turns are much faster, and diving is quite a bit steeper. Less g-force in saddle on toggle spirals than sabre. I have not tried any high performance landings with the canopy yet, but have landed it in conditions from 0-15mph wind.
Openings are the biggest change.
I am learning to fly the opening, which is slow enough to watch and react to. Three openings resulted in corkscrew dives, the first was corrected with brake release, the second two were corrected by steering with my body in the harness prior to releasing brakes. It appears to me that this opening behavior will be completely controllable with more time in the saddle. I am waiting also for a Samurai 150, and will review that after I get some jumps on it. I plan to put another 10-15 on the vengeance next weekend prior to sending it back.
