    Hello, I will try to keep this as sort as possible but basically no matter what I do I can seam to get rid of the FPV interference issues on my DJI F450 Quad.

    Every thing is fine until the throttle gets to about half stick (about take off power) then the video feed just cuts out and doesn't return until you land the quad. You can see the interference building as the rotor speed increases until the its just static. Here is a list of things I've tried in order to fix the issue:

    *Ive tried changing the channels on the video transmitter and if anything that just made it worse because on at least 2 channels the feed cut outs as soon as the quads remote transmitter is turned on.
    *Ive put the video transmitter, camera and power supply in pretty much every place around the quad it will fit and makes no difference.
    *Ive wrapped the video transmitter, video out cable and the ESC in tin foil to try to block the interference.
    *I got cloverleaf aerials for the transmitter and receiver to try to boost the signal and no change over the stock ones!

    So I am completely out of ideas on how to fix this, cos I know other people have FPV set-ups without any issues so I just don't get what wrong!

    I should also probably mention that the FPV system is separate to the quad so it has its own battery and I ve tested the FPV system away from the quad and it works perfectly. I will attach some picture that I hope will help show the set up and I have listed my build below. So anyone that could give me any ideas on how to fix this would be really amazing.

    Quad: DJI F450 Kit with NAZA lite ,GPS, e300 ESC and 2212 920kv motors
    Quad Radio: Turnigy 9x
    Video Gear: Boscam FPV 5.8G 400mW AV Receiver RC805 with Transmitter TS353
    Camera: Mobius

    If you are using JST connections for your vTx power supply - check them, I've had loose connections before.... also on that note check for loose/poor solder connections etc. Although it should not make a difference can you mount your vTx on the bottom and point the antenna downward? Just shootin in the dark with ideas...
