Description
The concept of Maclan Racing MRR Series motor is to design a top performance motor in competition level with supreme quality standard. The goal is to build a 1/10 motor to suit the requirements of professional drivers and weekend club racers alike. It was designed to perform and compete out of box.
The MRR modified class motors (3.5T to 9.5T) were developed with our factory drivers. We focus on the delivery of all controllable power to the wheels with maximized efficiency for high speed modified class applications.
The MRR 13.5, 17.5, and 21.5 are designed for the most competitive applications in the RC car racing. With the latest hall sensor technology and highest grade copper wires, we make no compromise in the stock racing. The completely rebuildable MRR series will also allow you to rebuild the motor in just few minutes to always remain the competitiveness on the top.
The MRR 25.5 meets the latest ROAR Rules for this specific class. Gone are the days of struggling with low end power. We’ve given the 25.5 class raw power that hasn’t been seen before. Faster, stronger and highest precision quality make this motor a must have.
- The latest hall sensor technology that precisely deliver all the RPM and torque to you.
- Short stator design for the lowest internal resistance and maximum performance (13.5/17.5/21.5)
- Highest grade copper wires provide maximum conductivity with no compromise.
- Heavy duty concave shape soldering tabs minimize the resistance and easy soldering work.
- CNC 6061 T6 full aluminum case with maximum venting design for optimized durability and airflow cooling
- Rebuild-able structure allows easy maintenance.
- ROAR approved.
