    ?

    • Added a communication baud rate of 1M for onboard SDK.
    • Fixed occasional iss​ue: the aircraft could not land automatically after reaching the Home Point during RTH.
    • Fixed issue: after setting the PWM signal to the Fchannel and restarting the flight controller, the F channel would output a minimum value before the preset value.
    • Fixed issue: when the remote controller signal was lost, the input for all the channels were cleared. Now only the input for A/E/T/Rch​annels will be cleared.
    • Fixed issue: when using a SBUS receiver, the aircraft could not exit Course Lock.
    • Fixed issue: when mapping two channels using an SBUS receiver, the configuration could not be saved.
