Here is a video I did on my UAV installation into a 4-port 5200. I had some issues in that this particular 4-port refused to work without the 4050 still in the mix. Since I wanted to keep the RF shield in place, it required some modification of the mod board.
Bryan's procedures are pretty much dead on so unless there is a need for something with more pictures...etc I'm leaving it with just my video and Bryan's instructions.
Bryan's instructions for installation are found on his blog here:
