R1 WURKS 2021 V21-S  Ultra Premium - 21.5T


Introducing the Brand new, redeveloped R1 Wurks V21-S Ultra Premium. If you thought the V21 was fast, wait until you try the V21-S! Massive improvements in all areas including punch, top end and brakes. Developed together with engineers and team drivers, the V21-S proves to be once again one step ahead of the competition. This motor is what other companies will be releasing next year.

Aligned Sensor & Hand Picked Stator

These motors have aligned sensor boards within 2 degrees from each pole or better using a motolyzer. These are guaranteed to be aligned using our in house motorlyzer not yours, this is not intended to be compared to your equipment. Results may vary from one motolyzer to another, SkyRc motor checker alignment will not match our test as well. Alignment guaranteed to the set optimum timing that the motor ships with, any timing changes will change the sensor alignment. 

Why hand picked stators? Lowest resistance stators is at the pinnacle of all types of motor tuning, 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. This stators are only guaranteed to have the lowest resistance at the time of purchase, based on what we have available on hand. Using our measuring equipment, not any other equipment. This will come with a printed resistance numbers, with individual phase resistance and overall average resistance.
