We've seen many different quadrotors, others big, others fast, others flexible... This musclecopter here, has six NTM Series 35-36A 910Kv / 350W, giving it the ability to lift up to some 7 kilos! Imagine that, it can lift two new-born children and replace a stork! The current that each motor draws with full load is 32 amperes, a total of 192 amperes for all six motors, some 2 KWatts of power!
