FPV Whoop Drone Happymodel Mobula8 O4 2S 85mm

Compact 2S digital HD whoop with DJI O4 Air Unit and wide FOV

Happymodel Mobula8 O4 is a compact digital FPV micro whoop designed for smooth HD flying on a 2S power system. Equipped with the DJI O4 Air Unit, it provides a clear and stable digital video feed. The included FOV extender widens the camera viewing angle, improving spatial awareness and making freestyle lines feel more natural and predictable.

The 85 mm frame, efficient EX1103 11000KV motors and tri-blade propellers create a balanced setup suitable for indoor practice and light outdoor sessions.
