is a fatom 6.5 v 4 a good motor ?

Fantom is one of the best for motors. They hand check and inspect every motor. It has to be perfect or they wont sell it. They recently got rid of $5000 worth or rotors because they didnt meet spec.

Great blueprinted motor. Much better quality than off the shelf products

I also think that fantom is a great motor, these motors are built for racing and represents the latest in R/C brushless motor technology. The Fantom ION Pro Brushless motors are setting the new standard for Power, Efficiency, Reliability & Performance......

thanks guys love my motor. its a v4
