Sub250 DollyFly25 V2 HD O4 Pro GPS 2.5-inch 4S (O4 Pro + ELRS 2.4G)

DollyFly25 has been fully upgraded. Equipped with the O4 Air Unit Pro transmission system, it delivers an exceptional imaging experience. The redesigned nose guard protects the O4 Air Unit Pro while adding a sleek, high-tech appearance.

The integrated protective frame, made from modified materials, combines high toughness with strength, effectively preventing damage from high-speed propellers. It also supports embedded COB light strips, adding extra visual flair to your flights.

A four-point suspension damping system efficiently eliminates jello and vibrations. With the O4 Air Unit Pro’s electronic stabilization and advanced imaging technology, you can capture stunning cinematic footage without the need for an external action camera.

At the rear of the frame, a dedicated GPS mount is designed to accommodate the SUB250 M10 GPS, enabling Betaflight Rescue Mode and providing additional safety during flight.
