5. Operating Your Supertruck
5.1 Basic Controls
- Throttle Trigger: Pull to accelerate forward, push to brake/reverse.
- Steering Wheel: Turn left or right to steer the vehicle.
- Trim Dials: Adjust steering and throttle trim to ensure the vehicle drives straight and stops when the trigger is neutral.
5.2 Driving Tips
- Start slowly to get accustomed to the vehicle's speed and handling.
- Avoid sudden turns at high speeds to prevent rollovers.
- Practice in open areas before attempting more complex maneuvers.
- Monitor battery levels and stop operation when power significantly drops to prevent over-discharging.
5.3 App-Adjustable ESC
The Electronic Speed Controller (ESC) parameters can be fine-tuned using a dedicated mobile application. This allows for customization of settings such as running mode, throttle curve, brake force, and more.
