This years set of motors has one of the highest power densities I have seen in FIRST. If you ran all of the 550s (all 8) into a single gearbox (low reduction, high speed), and put a large prop on it, you could get some substantial lift.

Motor power breakdown:
-AndyMark motors (AM- 0912)> 180.83W * 2 = 361.66W (current is below limit)
-Banebots RS-550-120-------> 253.52W * 4 = 1014.08W **(slightly less due to current limits, at this power level, they draw 43.2 amps each)
-Fisher Price 00801-0673-----> 291.59W * 2 = 583.18W **(prob. not quite this high, this would require 54.76 amps per motor)
----> this comes out to 1958.92 Watts, theoretically. So, How much would that be able to lift? (more specifically, how much would that be able to lift using a propeller?)
