Final Setup and Pre-Flight Checklist

1. In the Setup tab, confirm the quadcopter model icon moves in the same direction as your physical frame.

2. In the Receiver tab, verify that all stick movements and switch toggles are displayed accurately.

3. In the Modes tab, cycle through your switches to ensure the correct ranges are activated for each mode.

4. Verify the correct motor rotation direction (ensure propellers are removed).

5. Confirm that the OSD elements are clearly visible and correctly positioned in your FPV goggles.

Install propellers only after all the above checks are successfully completed and before your first test flight.
