This fan unit is provided with the Kyosho F-15, Intruder, F5 Phantom and F22 Raptor. The motor is 20mm diameter x 40mm long, and it has a 3mm shaft. At 15A on 3S the motor is running at peak efficiency. Unfortunately it does not quite reach its full potential because the fan pitch is quite low and unloads at high airspeed. This reduces the motor's current draw, so it becomes less efficient as airspeed increases!
