    I am new to the forum and to the drone world as well.

    I bought a built drone (by experienced builder) on frame DJI F550 flame wheel. Drone worked fine, then I did not use it for about a month and now transmitter won't connnect to receiver.

    In reality, it is like this:
    - turn on transmitter Turnigy XR Pro (FR SKY DJT telemtry); red light is solid and green light is flashing on telemetry module (both pins are set up on OFF)
    - turn on drone, press safety switch, wait untill GPS is set up (red light is solid, blue light is flashing)
    I use receiver FR SKY D4R-II. Red light on receiver is flashing. Transmitter never conects to receiver and I do not know why.
    When I pair drone with Mission planner, I am getting message "pre arm throttle below failsafe".

    I would appreciate any advice and help.

    Thank you!
