You're allowed 4 of them in FRC, and they run reasonably high power and definitely high speed if you take the planetary gearbox off. They're similar power to a CIM, but aiming more on the speed side than the torque side, which is better for propeller usage, and they're lighter, which is better for flight usage. An RS-550 might also work.

+1 RS-775 would be much better suited. One of the few large brushed quad rotors I've seen used motors close to RS-775. I still seriously doubt that you will be able to pick up a 17AH battery, my 2100 watt hexa is not able to lift that amount while staying stable
