    Firmware for CrossFlight


    Attention: Flashing firmware for different drone models to the flight controller will reset all current parameters, while flashing different versions of firmware for the same model will not. To preserve flight controller parameters, please export and save them first.

    1. The firmware CrossFlight supports:

    The CrossFlight can only upgrade the firmware from Radiolink and cannot upgrade the open-source firmware. The default firmware of CrossFlight is for Multicopter.

    2. The Mission Planner for parameter setup that CrossFlight supports:

    The CrossFlight can set parameters by Radiolink Mission Planner, ArduPilot Mission Planner, and QGC Mission Planner.

    3. The Mission Planner for firmware update that CrossFlight supports:

    ① Connect the CrossFlight to the Radiolink Mission Planner; there is a default (d5a4c778) that can upgrade the firmware by both the Radiolink Mission Planner and ArduPilot Mission Planner.



    ② Connect the CrossFlight to the Radiolink Mission Planner, there is without a (d5a4c778) that can also upgrade the firmware by both the Radiolink Mission Planner and ArduPilot Mission Planner, but you need to upgrade the firmware to the latest version below and Update the Bootloader first.
