Hello, I have been flying my DJI Phantom 1 for about a year now. I bought it used and it came with a lot of upgrades. The person I bought it from said the fpv works and it came with Fatshark goggles and a 7in monitor on the controller but it seems the transmitter and/or receiver has gone dead as I cannot get any video fee on either. I was looking at replacing the transmitter/receiver but was trying to get some input on what would be a good set up. Also would like to add an ISOD but not sure if the Phantom 1 can. Thank you for your input.
