Tekin Pro4 HD 4-Pole Brushless 550 Motor w/5mm Shaft (4,300kV)

This motor is about as good as the pro4 540. Didn't notice any more torque or top end compared to the other. But this motor will run cooler with very close to the same performance. If you have the 540 just stick with it. But if your in the market for a new 4x4 motor this is what I would buy due to cooler temps
