- Use this guide when the air unit suddenly loses video or disconnects during operation.
- The aircraft operates normally immediately after takeoff and during slow flight, but the video suddenly cuts out when applying more throttle or performing rolls and other aggressive maneuvers.
- This issue is most common on DIY-built aircraft and is often caused by insufficient output from the flight controller BEC. High-power devices such as the Avatar GT 2W and Moonlight require relatively high power.
- This issue is not limited to high-power air units. Devices such as the Avatar 1S may also experience the same problem if the flight controller BEC cannot provide sufficient power.
- A 12V, 2–3A BEC is recommended, or connect the air unit directly to a suitable battery voltage to ensure a stable power supply.
- After a minor impact or crash, the video feed briefly disconnects and then returns to normal.
- Set a multimeter to continuity mode and check whether the circuit GND or VCC is electrically connected to the exposed edge of the carbon-fiber frame.
- Remove the air unit from the frame and connect it directly to the battery without passing through any other onboard electronics. Test whether the air unit operates normally on its own.
- If the air unit works normally when tested independently, the issue is likely elsewhere in the aircraft rather than in the air unit.
- Motor mounting screws may be too long and may contact the motor windings, causing a short circuit. Replace them with shorter screws.
- Camera mounting screws may be too long and may have damaged the camera housing, allowing the camera circuit to short against the carbon-fiber frame. Replace them with shorter screws.
- Remove the air unit from the frame and connect it directly to the battery without passing through any other onboard electronics. Test whether the air unit operates normally on its own.
- If the air unit works normally when tested independently, the issue is likely caused by the aircraft installation rather than the air unit itself.
- Route the coaxial cable away from the ESC. Do not run the cable directly across the top or bottom of the ESC.
-
With the aircraft on the ground and the motors disarmed, gently tap or shake the frame and check whether the video feed disconnects or the screen goes black.
-
Or the air unit LED flashes green slowly.
- Reinstall the coaxial cable at both the air unit and camera ends, and make sure both connectors are securely seated.
- Replace the coaxial cable with a new one if necessary.
- The air unit LED flashes red and green rapidly, and the receiver unit UI displays a high-temperature warning.
- Use a cooling fan to provide airflow over the air unit during bench testing and configuration.
- After powering on the aircraft, take off promptly so that airflow during flight can cool the air unit.
- This issue most commonly occurs during prolonged ground testing. The air unit continuously processes HD video while operating, causing the main SoC to heat up quickly.
- When the temperature exceeds 110°C, the device enters thermal protection and shuts down. It will restart once the temperature has dropped sufficiently.
Do not leave the device at a high temperature for an extended period. Although thermal protection shuts the device down when it becomes too hot, prolonged exposure to high temperatures may still damage internal components.
If the issue persists, contact an official support channel for further technical assistance.
