Optical Flow PosHold FPV Racing Drone F108

Radiolink F108 – 2.5" Optical Flow Position Hold FPV Racing Drone Powered by the built-in Radiolink ArduBeta_AIO all-in-one ESC & flight controller, the F108 features a proprietary inertial navigation algorithm that ensures short-term position holding even when optical flow data is unavailable. During high-speed flight, it stops instantly when the stick is released — solving the common issues of losing control or failing to hold position when optical flow is lost at high speeds. The updated Kalman fusion algorithm overcomes the limitation of open-source flight controllers that only support terrain-based altitude holding in optical flow mode. Now, when flying over stairs or seats, the drone no longer experiences sudden altitude jumps.
