Radiolink Byme-D Delta Wing Flight Controller

The Radiolink Byme-D is a 4.5 g gyro-stabilised flight controller for model aircraft with mixed elevator/aileron (elevon) control — delta wings, flying wings, paper-plane style foamies and jet models such as the SU-27 and F-22. It takes an SBUS or PPM signal from the receiver, drives the left and right elevon servos directly and comes pre-tuned.

Key features

• Three flight modes: Stabilise, Gyro and Manual
• 3-axis gyro and 3-axis accelerometer with full attitude estimation and digital filtering
• Elevon outputs: left servo, right servo and throttle, with the fourth channel unused
• No calibration or parameter tuning needed before the first flight
• Status LED and servo-direction button for setup on the bench

Specifications

• Sensors: 3-axis gyroscope, 3-axis accelerometer
• Receiver input: SBUS, PPM
• Outputs: CH1 left servo, CH2 right servo, CH3 throttle
• Input voltage: 5–6 V
• Dimensions: 35.5 × 15.5 × 10.5 mm
• Weight: 4.5 g with wires
• In the box: flight controller, receiver connection cable, double-sided tape

Light enough for small indoor wings. Run it from a 5–6 V supply such as the ESC's BEC. It is not a multirotor controller — for a quad, pick a Betaflight or ArduPilot board instead.
