FMS Reflex V3 Stable Flight Controller

The FMS Reflex V3 is a sophisticated, high-performance flight stabilization system designed to act as a virtual "co-pilot" for fixed-wing RC aircraft. Engineered for both novice pilots seeking a safety net and veterans looking for rock-solid stability in adverse conditions, the V3 utilizes a high-speed 32-bit ARM processor alongside a precision 6-axis sensor array (3-axis gyro and 3-axis accelerometer). This hardware stack allows the Reflex V3 to counteract external disturbances like wind gusts and turbulence in real-time, providing the smooth flight characteristics of a much larger aircraft.

A major evolution in the Reflex series, the V3 features integrated Bluetooth connectivity, allowing pilots to fine-tune parameters and switch aircraft profiles via a dedicated mobile app. This removes the "FMS-only" barrier of previous versions, enabling the Reflex V3 to be utilized in almost any fixed-wing airframe, including warbirds, EDF jets, and civil trainers. With support for SBUS, PPM, and PWM inputs, it offers universal compatibility with modern radio systems. Whether you are conducting a university aerospace test or a tactical sUAS field operation, the Reflex V3 provides the mission-critical stability needed to protect your hardware and ensure a successful flight.
