I recently bought the Turnigy action cam and am in the process of hooking it up to my Quanum FPV system. I am using the usb video out cable and have hooked it up as you all have in this thread and have changed the tv mode to "on." But still no success. The only thing I can think of is the firmware. How do I find out the firmware version of my cam,,,,,,,and if it needs updating,,,,,can anyone tell me how to perform the upgrade or where to go for instructions? Thanks bunches! !
