The T-Motor AM670 is a powerful motor for 3D models in the 67-70" category with a weight of about 5Kg. 

It is very well made. Thanks to the ripples on the motor bell and the hollow shaft, the motor is more robust and lighter than its predecessors. The ratio of the diameter and engine height ratio is 3:1 for higher torque and better cooling

1.Suitable for 67"-70" 3D plane 

2.Evolution of hollowed lightweight design

3.with up to 10132g of thrust
