Fixed-wing Wireless Configuration

Supports wireless configuration via Speedybee and QGroundcontrol apps. Easy and convenient configuration, allowing you to focus on the joy of flying.

Fit All You need

Need detailed tuning but mobile apps don’t support? With BLE, Wi-Fi, and classic Bluetooth, there is always a way to connect that fits your needs.

Long press BOOT button for 6 seconds to switch between 4 modes: BLE, Wi-Fi, classic Bluetooth SPP, and turn off wireless.

Plug and Play

Plug in your digital VTX, receiver, camera, analog VTX, and GPS to complete your build in no time. Prefer soldering? Just flip the board and start working on it.

Supports plug and play with DJI O3/RunCam Link/Caddx Vista/Caddx Walksnail Avatar

INAV/Ardupilot Dual Firmwares

INAV for handling FPV flight easily; Ardupilot for advanced capabilities. Stabilize your flight, automatic take-off, Wing Racing, and Formation Flying... whether you're a beginner or an expert, this flight controller can fulfill all your flying dreams.

Full MCU pin breakout, no more interface selection issues

• Uart1: ELRS/TBS receiver
• Uart2: SBUS input or other peripheral
• Uart3: GPS module
• Uart4:Telemetry module or other peripheral
• Uart5: Digital VTX or Analog VTX
• Uart6: On-board Wireless controller

Up to 6 UART ports for easy expansion, allowing you to connect various external modules,from GPS to Digital VTX.

Support Configuring 11 PWM Outputs

Up to 11 PWM outputs can be configured for motor and servo control, making this flight controller suitable for a variety of fixed-wing planes, including conventional layout planes, V-tail planes, planes with flaperons, and VTOLs.

Multi-layer PCB Design

Designed with separate layers for the power supply, FC, and function modules, effectively resolving sensor interference caused by power circuits.

Supports VTOL

Use a fixed-wing plane with VTOL, multi-copter flying, and you can do it too! Control VTOL plane takeoff and landing manually or autonomously with Ardupilot's QStabilize, QLoiter, and QRTL modes

Various plane models including Tiltrotor, Quadplane, flying wing tail-sitter , etc.

ELRS/TBS Receiver Direct Plug-in

Use OpenTX/EdgeTX telemetry data to monitor your plane's status.

Simply plug the ELRS/TBS receiver into the flight controller's UART1 port and enable lua script in OpenTX/EdgeTX to display telemetry data.

4x LED Strip Plugs

4x LED strip help to make your plane shine. With connectors, no need to solder. Short press the BOOT button to switch different effects and make your plane more visible in the sky. Press BOOT button for 3 seconds to switch to FC control for LED lights.

Built-in Battery Checker

Built with a 4-level LED battery indicator, quick to check the left power for Lipo. You can fly anywhere free even without your lipo checker.
