Relay use?

I keep looking, but I cannot find a straight answer on how to use my r/c transmitter to control the onboard relay.  I enter CLI and go into setup- type 'tune 9' and it shows a change from 0 (.015) to 1 but does not activate the relay.  I have searched the forum pages repeatedly, but its all vague on generic use. I do not want to activate the relay just through the APM-  I want to turn on my lights at any time via my transmitter without the computer.  Are there options built in for this? Please help...

    You answered your own question!
    Just use your R/C transmitter!!
  • Arducoptor in this case. I have a few 1w cree xlamps that I want to switch on remotely- and off to save power. The relay was one of the reasons (among many) I got the Ardupilot hardware- I don't want to buy and fly more electronics if the AP can do it.

    ArduPlane or ArduCopter?  This is not a feature in ArduPlane.  Don't know about ArduCopter.  If you just want to turn lights on from your rc transmitter, you don't need to run that through APM at all - there are RC LED control boards you can use for that.
