Product overview
The RadioLink Byme-A is a flight-controller component for straight-wing aircraft, including F3P aerobatic models, four-channel trainers and scale aircraft. Its sensing architecture combines a three-axis gyroscope with a three-axis acceleration sensor, supported by attitude and control algorithms and digital filtering. At 4.5g including wires, it accommodates small indoor models. Integration uses a receiver with SBUS or PPM output, with channel connections assigned to aileron, elevator, throttle and rudder; the throttle connection receives power from the ESC BEC.
Six selectable modes cover two vertical-flight modes, stabilized level flight, assisted aerobatics, gyro assistance and manual control. Gyro Mode does not automatically level the aircraft, while Manual Mode removes algorithm and gyro assistance and requires advanced piloting skills. Calibration uses both transmitter sticks moved to the outside corners without dedicated parameter setting. A status/servo-phase indicator and servo-phase adjustment button support setup. The supplied package contains the controller, a receiver connection lead, double-sided adhesive tape and a packing bag; it is a controller package rather than a complete aircraft.
