    Hi all,

    I've a JDx 509G toyquadcopter with a 5.8G FPV http://www.gearbest.com/rc-quadcopters/pp_240434.html?wid=21

    I've had a crash from about 150 meters high all the way to the ground. Luckily it landed on long grass so the only thing i had to replace then was an engine gear.

    However i now discovered that my FPV signal is lost when i takeoff and the screen then turns black or green after takeoff.

    I have done the following things untill now to try and get this fixed

    1. disassembled the entire quad inculding the camera - every screw - checking for faulty cable connections - nothing found - and put some glue on the cable connections on the mainboard.
    2. took the camera of the quad and with the camera connected (not affected by the quads vibrations) toke off to a few centimeters above ground. the camera still works correctly.

    Above does still points to the issue is being caused by vibration after the crash.. does anyone has a suggestion on how i can fix this?

    Friendly regards,

    Sounds like you've covered all avenues. Have you thoroughly inspected the cam's antenna? Maybe try some reinforcement there, hot melt glue etc.
