Sub250 OasisFly25 O4 Pro 2.5" Freestyle Quad (ELRS)

Overview:
The Sub250 OasisFly25 is a compact 2.5-inch freestyle drone designed to deliver powerful performance in a smaller, more portable size. Built around a deadcat 135mm wheelbase, it provides a stable flight profile while keeping props out of view, making it particularly suitable for capturing clean HD footage during flights.

Powered by a 4S setup with 1404-class motors, the OasisFly25 offers a noticeable step up in power compared with micro whoops, while remaining efficient and manageable for tighter flying environments. The result is a responsive and agile quad that can handle freestyle manoeuvres, cruising and general FPV flying without the bulk of a larger 5-inch build.

At the centre of the system is the DJI O4 Pro Air Unit (version dependent), providing high-definition digital video transmission along with onboard recording capability. This makes the O4 Pro version well-suited to pilots who want both high-quality immersive FPV and usable HD footage from a single compact platform without the need for a GoPro.

The OasisFly25 is also available in a “Without O4 Pro” (WTFPV) version. Although the airframe is designed for the DJI O4 Pro, you may want to install another FPV system into the frame or use your existing camera and VTX. This allows you to take advantage of the same core airframe and performance characteristics while creating your own custom build.

With a lightweight design, efficient 4S power system and protected internals, the OasisFly25 sits between micro drones and full-size freestyle quads, offering a balanced option for pilots who want performance without excess size or weight for pulling off freestyle tricks and manoeuvres at speed!
