Radiolink Byme-A Fixed-Wing Flight Controller

The Radiolink Byme-A is a 4.5 g gyro-stabilised flight controller for fixed-wing aircraft — 3D (F3P) planes, four-channel trainers and scale models. It sits between an SBUS or PPM receiver and the servos and comes pre-tuned, so there are no PID parameters to set before the first flight.

Key features

• Six flight modes: Vertical with multicopter logic, Vertical with fixed-wing logic, Stabilise, Acrobat, Gyro and Manual
• Vertical modes hold the plane in a nose-up hover, so beginners can learn prop-hanging step by step
• Three-axis gyro and three-axis accelerometer for self-levelling and attitude hold
• Four outputs: aileron, elevator, throttle and rudder
• Powered from the ESC's BEC through the throttle channel; status LED and a button for setting servo direction

Specifications

• Sensors: 3-axis gyroscope, 3-axis accelerometer
• Receiver input: SBUS, PPM
• Outputs: CH1 aileron, CH2 elevator, CH3 throttle (ESC), CH4 rudder
• Flight modes: 6
• Power: ESC BEC via CH3
• Weight: 4.5 g with wires

New pilots can start in Stabilise for level-flight practice and move to Gyro and Manual as their skills grow. The receiver must output SBUS or PPM — a PWM-only receiver will not connect.
