I installed the lightbox sr in my new plane I am working on. I am using all 4 ports with basic led's and programmed the beacon, strobes, solid leds, wig wag lights. I have the system set in PWM on a 3 way switch off, everything on except wig wag, everything on with wig wag. I have had several cycles of turning the lights on and off with no problems. However, I was turning my tx and rx on and off in no particular order with the lights on and when I turned my tx back on to connect to the plane I was unable to turn the lights on and off with the 3 way switch. I also had no functionality on my AR12120 and JR12x tx on Aux 3,4,5,6, and 7. The other ports such as ail, rudder, elev, throttle worked. I was able to simulate this problem over a half dozen times. I originally had multiple components servos, tech aero, lightbox etc in the equation and was able to eliminate all the components except the lightbox and still ran into these issues.
I even tried another brand new rx same problems. I have never run into anything like this before. By the way this is all off a A123 pack and some of the lights have resisters. I really like the unit itself but I am really disappointed in the fact this could cause a crash when I thought this unit was fail safe all around.
