How to add 5.8ghz FPV to a Hubsan H501c for $12 using the drones existing on-board camera. You will need to buy an FPV monitor if you don't have one already.
For parts search google, ebay or banggood using these search strings;
$12 transmitter "Eachine VTX02"
$28 monitor "JJRC C4002 5.8ghz FPV monitor"
note: $28 monitor comes without antenna or charger;
$2.98 antenna "5.8G FPV Omni Antenna SMA Male"
$2.50 charger "USB Charging Cable Syma C4001 Camera FPV Screen"
FROM RICH ANGE: The New H501C has a different camera board that does NOT have the required solder points shown in my video. BUT the required solder points are still available just now on the main board so you can still do the mod. Here is a picture showing the new main board and the required solder points;
