7. Operation
Understanding the basic operation of your Boxer Crush controller is crucial for effective use:
- Gimbals: The AG01 Hall Gimbals control the primary movements (pitch, roll, yaw, throttle) of your RC model. Practice smooth and precise movements.
- Switches and Knobs: Utilize the various switches (SA, SB, SC, SD, SE, SF) and knobs (S1, S2, T1, T2, T3, T4) for auxiliary functions, flight modes, and fine-tuning. Refer to your model's setup in EdgeTX for specific assignments.
- Display and Navigation: The monochrome LCD displays telemetry data, model settings, and menu options. Use the navigation buttons and scroll wheel to move through menus and adjust parameters.
- Binding: To control an RC model, the controller must be bound to a compatible receiver. Consult your receiver's manual and the EdgeTX documentation for the binding procedure specific to your ExpressLRS setup.
8. Maintenance
Proper maintenance will extend the lifespan and ensure the reliability of your Boxer Crush controller:
- Cleaning: Use a soft, dry cloth to clean the exterior of the controller. Avoid using harsh chemicals or abrasive materials.
- Storage: Store the controller in its carrying case in a cool, dry place, away from direct sunlight and extreme temperatures.
- Battery Care: If storing for extended periods, ensure batteries are charged to a storage voltage (typically around 3.8V per cell for LiPo/Li-Ion) to prevent degradation.
- Gimbal Maintenance: The AG01 gimbals are designed for durability, but avoid exposing them to excessive dust or debris. If adjusting tension, proceed carefully to avoid stripping screws.
9. Troubleshooting
If you encounter issues with your Boxer Crush controller, consider the following common troubleshooting steps:
- Controller Not Powering On: Check battery charge level and ensure batteries are correctly installed. Verify the power button is fully pressed.
- No Response from Model: Confirm the controller is bound to the receiver. Check the model's power supply and receiver connection. Ensure the correct model profile is selected on the controller.
- Erratic Control: Recalibrate the gimbals through the EdgeTX system menu. Check for any physical obstructions or damage to the gimbals.
- Display Issues: If the display is blank or flickering, try restarting the controller. Ensure the battery is adequately charged.
