FrSky R9 Pilot F765 All-in-One Flight Controller


In Stock

FrSky Radio Control Systems
PDF icon Manual2 MB

The FrSky Pilot series flight controller is an all-in-one board that supports comprehensive flight control functions with pre-installed powerful INAV (support of other open-source software like Ardupilot and Betaflight are ongoing) and F.Port 2.0 software. This control system is targeted towards RC hobby enthusiasts who are looking for a complete system combining power management, a powerful graphic FrSky OSD, and plenty of IOs.

This FC is designed around use in fixed wing aircraft, but can be used for multirotors with up to 12 motors! You can connect up to 12 servo outputs to this flight controller, 6 UART ports2 analog inputsvideo in/out and even I²C interface.

There are three versions of the FrSky Pilot that offer different receiver options. Two come with an integrated receiver: The RXSR option is for use with FrSky ACCESS radios and the R9 option can be used with FrSky's long range radio control. You can also purchase without receiver to use your own Rx. Via a conventional UART connection, the FrSky Pilot is compatible with all F.Port 2.0 capable receivers (Archer and Tandem Series Receivers, etc.) and SBUS receivers.

The FrSky Pilot is comprised of a three-layer stack:

  • A mainboard providing power for servos and for a video system with switchable voltages, current measurement and general connectivity (6 full UARTs, I²C, 12 servo/motor outputs, 2 analog inputs, video input/output).
  • A processing board using a powerful STM32F765 MCU at its core, boasting 1MB of flash memory, and 512KB of RAM capable of running the INAV, Ardupilot and Betaflight flight control software. It integrates an ICM20602 IMU, FrSky’s latest graphic FrSky OSD, and an SPL06 high precision barometer. An SPI bus connector allows for optional connection of a second vibration isolated IMU, which can be mounted to the board, or other peripherals. An SD card slot allows for data storage including BlackBox logging. It also includes a piezo audio transducer for system notifications and lost model locating.
  • FrSky Pilot has two flat flexible cable interfaces on the top of the FC. One is for the RXSR-FC or R9MM-FC radio receiver module, another for connecting an external Gyro module with ICM20601/ICM20602/MPU6000 IMU (not included).
