ORCA Modtreme 4 M4 6.5T Sensored Brushless Modified Motor – MO26MTM465T

The ORCA Modtreme 4 M4 6.5T Sensored Brushless Motor is a next-generation competition motor developed for racers demanding outstanding speed, efficiency and precise power delivery.

Designed for modified-class 1/10 scale touring cars and off-road racing vehicles, the Modtreme 4 combines a hand-wound stator with an optimised 12.1mm rotor. Its sensored design provides smooth startup, accurate throttle response and predictable power delivery throughout the RPM range.

The redesigned motor housing improves cooling while reducing overall weight by approximately 3% compared with the previous generation. ORCA has also moved the solder terminals inward, positioning more of the motor’s mass towards the vehicle’s centreline. This improves chassis balance and helps the vehicle transition more quickly through rapid left-to-right direction changes.

Factory-installed titanium motor screws reduce weight at the highest point of the motor while providing excellent strength and durability. Its standard 540-size dimensions allow installation in a wide range of competition RC chassis.

The 6.5-turn winding offers a strong balance of acceleration, top speed and controllability, making it suitable for modified racing applications where manageable power delivery is just as important as outright performance.
