Very nice install! 2200W should be insane; I had about 1700W on mine and it was ballistic
FWIW, I had a Turdigy 5065 400kv motor, and found an 8" pitch to work better: I tried 16x8, 16x10, and 17x8 APC's. The 16x10 would "cavitate" in hover, and suffered poor pullout as such. It did have more speed, and made snaps, tumbles and such more violent.
