This 1.8” Carbon Fiber spinner is a perfect match to your Ultimate AMR. The combination of precision CNC machined Aluminum back plate and our German made precision prop adapter allows true spinning without motor’s performance deterioration.
 
The new CF spinner is incredibly lightweight (only 9.5gr/0.335oz!!) and has a beautiful shiny finish.
 
We DO NOT recommend using a poor quality prop adapter, such as those supplied with most motors available on the market. Poor machining results in un-centered spinning and excessive vibrations which will affect the motor efficiency and performance, and may in the long run cause damage to the spinner cone and wear out your motor’s ball bearings.

All spinners are tested in our facility (using our German made prop adaptor) to verify they spin centered and true before shipped.
