Next-Level Brushless Performance
At the heart of the system is a high-power 3350Kv brushless outrunner motor paired with a brushless ECM using Field-Oriented Control (FOC) technology. This combination provides:
-
Superior low-speed torque and throttle control
-
Smoother power delivery
-
Higher efficiency
-
Increased overall performance
Whether you're climbing, descending, or navigating technical terrain, FOC ensures precision control at crawling speeds while still delivering serious power when you open the throttle.
