RadioLink Byme-DB Flight Controller for Micro Fixed-wing Aircraft

The RadioLink Byme-DB is a compact, lightweight flight controller specifically designed for micro fixed-wing aircraft. Weighing only 3.6g (including wires) and measuring just 29×25.1×9.1mm, it integrates a three-axis gyroscope and three-axis accelerometer to deliver outstanding flight stability and control. With support for both SBUS and PPM signals, this controller is ideal for a wide range of model aircraft with mixed elevator/aileron controls.

Byme-DB supports three flight modes—Stabilize Mode, Gyro Mode, and Manual Mode—catering to beginners and experienced pilots alike. It is perfect for various aircraft types including delta wing, paper plane, J10, SU27 (with or without rudder), and F22.

Key Features

• Three Flight Modes:

  • Stabilize Mode (Beginner Mode) – Flight controller assists with balance; limited to 70° roll and 45° pitch for safety.

  • Gyro Mode (Advanced Mode) – Provides stabilization without auto-leveling; ideal for practiced flyers.

  • Manual Mode (Master Mode) – Full manual control with no gyro assistance; allows acrobatics like loops, rolls, and low-altitude freestyle.

• PID AutoTune:

  • Automatically tunes PID parameters based on the proven performance of the Byme-D series.

  • No manual tuning required—only mode switch and calibration during first use.

• Ultra-Compact & Lightweight:

  • Total weight: 3.6g (0.13oz)

  • Dimension: 29×25.1×9.1mm

  • Perfect for indoor and micro models with limited payload capacity.

• Multi-Model Compatibility:

  • Supports delta wings, SU27 with rudder, and even paper planes.

  • Suitable for mixed elevator and aileron configurations.

• Plug & Play Setup:

  • Pre-tuned, requires only mode switch configuration and calibration.

  • No software needed for PID tuning.

RadioLink Byme-DB flight controller for micro fixed-wing aircraft. Features: multiple models, three flight modes, SBUS&PPM support, PID autotune, compact size.

RadioLink Byme-DB flight controller improves stability for model airplanes. It includes a three-axis gyroscope, accelerometer, and algorithms for stabilize, gyro, and manual modes, helping beginners learn to fly easily.

Byme-DB flight controller offers three modes: Stabilize, Gyro, and Manual. Perfect for beginners and pros, enabling easy, fun flights with exceptional skill.

Stabilize Mode (Beginner Mode) assists aircraft balance, ideal for beginners. Rolling angle limited to 70°, pitching angle to 45°.

Gyro Mode: Enhances flight stability without auto-leveling. Ideal for experienced pilots practicing better aircraft control.

Stabilize Mode (Beginner Mode) assists aircraft balance, ideal for beginners. Rolling angle limited to 70°, pitching angle to 45°.

PID AutoTune simplifies setup for Byme-DB, a flight controller tested over five years. It optimizes PID parameters and includes a fourth channel output. Compatible with traditional delta wings and rudder-equipped models, it requires no manual tuning—just initial wiring, switch setup, and calibration. The system is ideal for micro fixed-wing aircraft, as shown in images of two planes flying over landscapes, demonstrating its real-world performance in efficient flight control.
