D-link dropping out

There is a failure mode on the 5 volt convertor that will send 7 volts to the radio on full battery voltage and then as the battery goes down so to does the output of the convertor. It acts just a like a resistor. I believe that the failure mode is caused by a reverse electrical connection at some point. Double check the output voltage of the convertor.
Blackflame, the camera body is connected to the negative lead of the power supply. If you have other frame shorts, it is possible to shutdown the power supplies in the PD as reported by it's designer.

Depending on the model of wireless adapter in use, the proximity of speed controllers to the wireless may have play in the issue. My teem found a few years back that when the speed controllers are running at a high voltage, the EM radiation produced can mess with wireless if the wireless is only a few inches away. An easy way to test to see if this is an issue is getting your wireless as far from your jags as possible (even just duck-taping it at max cord length works). Keep in mind that moving it may also solve other issues.
