This is the new Super Short motor! The can is 6mm shorter and 6 grams lighter than the regular V21-S motors. This improves the center of gravity in the car, pushing the motor more towards the center of the chassis.
This new Super Short motor is now ROAR approved.
About "Hand Picked + Aligned Stator" versions:
These motors have aligned sensor boards within 2 degrees from each pole or better using R1's in-house motorlyzer. This is not intended to be compared to your equipment as results may vary from one motorlyzer to another. For example, SkyRC motor checker alignment will not match R1's motorlyzer. Alignment guaranteed to the set optimum timing that the motor is shipped with. Note any timing changes will also change the sensor alignment.
Why hand-picked stators? Lowest resistance stators is at the pinnacle of all types of motor tunning, low resistance delivers the highest possible performance gain out of any motor tuning combined.
This motor is assembled with a stator that is hand-picked. Hand-picked stators are the lowest resistance stators available in our warehouse at the time of purchase, based on what R1 has available on hand.
Using R1's measuring equipment (not any other equipment) to produce printed resistance numbers, with individual phase resistance and overall average resistance.
Note we will not accept request for returns stating that you did not get the resistance numbers that you were expecting. This motor will not come with any additional parts or service. This hand picked stator is also available on a different listing with aligned sensors. All sales are final.
