Have dx5 with non avc reciever. MOD kill switch. Light flashes without radio on, no light with kill switch activated from radio, solid red when running. Never touched avc in radio, just ditched avc receiver for non avc receiver. Using aux 2 for kill switch, button E . Shows 1oo either to left or right of screen when button pushed, I think to right is running, red light on. This is about the best I can help being you have different kill switch. If you have a plug tester, 5 bucks at harbor freight, you can watch for spark while cycling thru button position. Lot easier to see and don't need to hold anything. Set choke after you find correct radio position, prime bulb till u see fuel in line, should pop 1st or 2nd pull. Open choke and should fire within 3 pulls or you might be fighting something else. Best of luck, hope she runs.
