Proper calibration ensures stable flight performance by fine-tuning the drone’s roll and pitch trim. Calibration is essential for correcting sensor offsets caused by the installation or soldering of the MPU6050 motion sensor. If the sensor is not perfectly level during soldering or has slight factory variations, it may introduce roll and pitch drift during flight. If the LiteWing drone drifts in any direction during hover, follow this calibration guide to adjust the roll and pitch trim settings in the mobile app.
Understanding Roll and Pitch Trim
Roll Trim: Adjusts side-to-side movement (left or right).
Pitch Trim: Adjusts front-to-back movement (forward or backwards).
If the drone is not holding position correctly when hovering, trim adjustments can help compensate for minor imbalances.
How to Calibrate Roll and Pitch Trim
1. Initial Setup
Place the LiteWing drone on a flat and level surface.
Power on the drone and connect it to the mobile app.
Ensure the system and Link LEDs blink, indicating the drone is ready.
2. Accessing Trim Adjustments in the App
Open the ESP-Drone App and ensure the drone is connected.
Open the Flight control settings from the settings menu. There you can find the Roll and Pitch trim settings.
3. Adjusting Roll and Pitch Trim
Before adjusting the trim values, fly the LiteWing Drone and see where it drifts. Adjust the trim values in slight increments until the LiteWing Drone is stable.
Drone Drifts Left or Right (Roll Adjustment)
If the drone drifts left, increase the roll trim value to a positive value (eg. 0.2).
If the drone drifts right, decrease the roll trim to a negative value(eg. -0.14).
Drone Drifts Forward or Backward (Pitch Adjustment)
If the drone drifts forward, increase the backward pitch trim to a negative value(eg. -0.10).
If the drone drifts backwards, decrease the pitch trim value to a positive value (eg. 0.2).
4. Testing and Fine-Tuning
Apply small trim adjustments and test the hover stability. If the drone still drifts, fine-tune the trim further in small increments.
Once stable, your LiteWing drone is ready for a stable flight!
