Frame Sub250 Oasisfly30 O4

The Sub250 Oasisfly30 O4 Pro Frame is a durable and lightweight 3-inch freestyle frame designed for both digital and analog FPV builds, including seamless integration with DJI O4 Pro. Its smart camera placement in front of the motors eliminates propeller edges from the view, while adjustable tilt (0–20°) ensures flexible flight styles. With 3mm carbon arms for strength, vibration-damped camera mounting, and protective 3D-printed side panels, the Oasisfly30 O4 Pro is built to withstand freestyle crashes while keeping your electronics safe and accessible.

The frame is designed for motors with 9mm and 12mm M2 mounting patterns and 20x20mm stacks. Mounting holes for video transmitters support both 20x20mm and 25.5x25.5mm.

- Designed for compact 3" freestyle drones
- Compatible with both digital and analog FPV systems (supports DJI O4 Pro)
- Front-mounted FPV camera – no propellers in view
