Thank you for the information. I've fitted my 502e with a 502s video transmitter and it works at close range. The 502e does not have a 5.8ghz transmit antenna on the drone so now I'm trying to locate a 502s antenna. Guess I should have purchased a 502s I the first place but I didn't know I'd get hooked on drones.
Yes, watch Drone Worship on U-tube, he has put together a 5.8 self contained camera from banggood, c4002 jjrc - h-16 and fpv watch to attach to the transmitter from hobby wow, Gtang +909, 2 inch screen, you will need legs and eBay has the listing, just scroll down to parts under hubsan 502e.
