I bought this as recommended by other reviewers, and one of my motors was really hot after a flight.

These are good motors, but they do need to be broken in before use. Just let the motor spin for a few minutes, then clean it out with compressed air. This is not a flaw of the motor construction, all brushed motors should be treated like this. However, most quads use brushless motors, I'm not sure why the V666 uses this brushed motor.
