I probably shouldn't have mentioned the Argosy thing, so please forget it.
Knowing DaveB & his 100% ratings, it just made me wonder if the lights had anything to do with him not flying it.
I doubt there is anything wrong with the model, but I had trouble with it a couple of times where I thought the landing lights were right, only for FlyNet to disagree.
I simplified the XML on mine so that it just did a straight on/off of landing lights instead of the more complex code that was in there.
If others are using it no problem, it was probably me using it wrong.
I did RTFM once but don't fly it often enough to remember.
