Default RE: Cheap but super good motor for flight

Anyone who suggests that a 215g motor can cope with 2000W is asking for a fall. The "rule of thumb" is that motors can cope with perhaps 3W/g input in terms of heat dissipation- for this motor that's 645W.... 9-10W/g in a cheap Chinese motor is a recipe for melt-down.
