Got it, thanks Dave. I'm working on the lighting system in the wings and tail right now. I agree this is a lot of work for some reason. Also, my Black.4 servo lead to the receiver broke at the board only after handling it a little bit on the bench. I contacted uniLight via there website about it and Ulrich got back to me right away about how to take it apart and solder the wires. Looking at the way they soldered the wires to the board they didn't tin or include flux on the ends of the wires. I redid each one under magnification reassembled it and the unit is working fine so far. Very impressed with the help from uniLight on this.
