I think that the 2212 is too big for this plane. It will require a larger pack. It definitely flies better to me at 10 oz. with the 340 and 480 packs. And power is awesome!, with a much lower wing loading. It also feels better with the 2208/34 on the 9x3.8 allowing it to come down better while in a hover. But flies a hair faster than I would like with the 9 and requires better throttle management.
