ULTRA PREMUIM is basically an updated version of the previous motor.(updated version approved by Roar & has passed tech at Roar events)
New stator has two front rings (makes your motor power more consistent throughout the run)
End wind (wire) is bonded in place to reduce vibration (improves initial acceleration & top end)
(no change in dimension,just improved performance) We also applied improved manufacturing techniques (proprietary) on both the same stator material & same wires (made in USA)
Compared to the previous motor based on beta user feedback, the motor improved acceleration,top end & power consistency throughout a race even at extreme temperatures (extreme temperatures not recommended,this will shorten the life of the stator).
