The STARTRC Payload Release System for DJI Air 3 / Air 3S is a light-controlled drone dropper designed for small payload delivery, drone fishing bait drops, event props, field testing, and creative aerial use.
This system is custom-fit for DJI Air 3 and DJI Air 3S. It uses the drone’s auxiliary light to trigger the release, so no extra remote controller or app is required.
The built-in photosensitive trigger system allows the payload release to respond to the drone’s bottom auxiliary light. Turn the light on to release the payload and turn it off to reset the mechanism.
This makes the DJI Air 3S payload release system simple to operate without adding another remote device to your flight setup.
This drone payload release system supports light payloads up to approximately 400g. It can be used for small item drops, fishing bait delivery, event props, outdoor testing, and other controlled open-area use cases.
Payload weight, wind, battery level, flight mode, and environment can affect flight stability. Always test with a lighter load first and avoid flying over people, vehicles, roads, or restricted areas.
Installed view on DJI Air 3S with clear sensor and body alignment.
The mounting structure is designed for DJI Air 3 and DJI Air 3S. When properly installed, it does not block the main vision sensors or cooling areas.
This fit-focused design is one of the key differences between a model-specific STARTRC drone dropper and a generic strap-on payload release device.
The top of the system includes a 1/4-inch screw mount, allowing users to connect compatible lightweight accessories such as small action cameras, fill lights, or compact search lights.
Use only lightweight accessories and always check flight balance before takeoff.
The built-in 50mAh battery charges in about 30 minutes and supports approximately 400 release operations per full charge.
Charge the module before use and test the release function on the ground before every flight.
