Have read a few posts of people having unexplained drop outs in control and the PV falling out of the sky. Update both the Main Controller AND Central Board firmware.IF YOU HAVE UPDATED THE RECEIVER FIRMWARE, YOU MUST UPDATE THE TRANSMITTER FIRMWARE ALSO. If the transmitter is using older firmware, DJI plainly states that you could have mysterious control loss and the P2V behaving unusually (loss of throttle/power, loss of directional control).
