The Maclan MRR V3 Competition Sensored Brushless Motor is the result of the latest efforts by Maclan Racing and is based on the successful V2 platform with various updates to improve overall performance. Improvements in this generation are significant and will make a noticeable performance gain.

NOTE: This motor should not be paired with the Reedy Blackbox 510R 2S ESC (ASC27004, ASC27005). These ESCs deliver 3.3V from the sensor port, and Maclan V3 motors require a minimum of 4.8V.   

Features:

• Engineered & Developed right here in the U.S.A.
• Updated 1-piece precision machined motor can design that eliminates the need for long motor can screws. Redesign uses a total of 5 short screws. It saves weight and no more optional screws required.
• Improved stator shape that meets the latest ROAR regulations for the highest legal performance.
• Realigned sensor positions for more accurate reading.
• Premium Ultra High Torque Rotor is now standard by default. You get best performance right out of the box. Available in 13.5, 17.5, 21.5 Turns
