I just wired up a ubec and turnigy on/off switch connected to four 5v laser diodes (4mw). I followed all of the instructions with the ubec into pixhawk main out 5 and the on/off switch into aux 3 (rc11). I also programmed the radio to use channel 8. The commands show up on radio calibration and setup ch8 for relay on/off on the tuning screen. I also tested the switch jumpers for switch on but i cant get lights to turn on. I used super thin 24awg wire for the lights - ok for 5v i assume? And are the lights too much for one ubec?
these are the ones i am using
