To use my RX-LCD5802 FPV monitor with my transmitter, I needed a simple mount for it. HobbyKing had one for less than $10 made out of carbon, so I picked one up to see if it would meet my needs.
To receive the image sent from my SkyZone TS5823 FPV transmitter, I bought a FPV LCD monitor with two built-in receivers, supporting diversity.
HobbyKing had a 10-30% sale on their whole store, so I just had to order some FPV-gear for my quad. To begin with, I needed a way to send video from my GoPro.
