Fair and Consistent Racing with Zero Timing

The G3-Handout ESC features a locked 0° timing design, making it fully legal for “blinky” and handout motor classes. It eliminates the variables, letting your driving and chassis setup speak for themselves.

---

6-Level RPM Speed Limit Function

Adjustable across 6 RPM limit settings, the ESC allows race organizers and drivers to comply with regulated motor speed rules. A dedicated LED indicator shows the selected speed limit gear, while Hobbywing’s accurate algorithm ensures smooth throttle response even at capped speeds.

---

Bi-Directional Motor Support

Supports both clockwise (CW) and counterclockwise (CCW) motor rotation for maximum flexibility in installation and vehicle type.

---

Built-in High-Voltage BEC

With a powerful built-in BEC delivering up to 8A peak and switchable output of 6V/7.4V, the Justock G3 easily powers today’s high-voltage, high-torque servos—perfect for competitive racing demands.
