Hi Dan most of mine are the standard DBCs about5 working and maybe4 spares in the drawer,but i do have 2 RC2 DBCs which because of the conections of the reciever fly leads ,they tend to break so have had a few issues with ,your idea of fitting plugs is a big improvement.most of the DBCs/DBUswork great have had very few problems with them,but have had a few problems with the small sound cards Dave uses.I think there is only 4 still working correctly.
When I have time will check outall the boards I havespare and let the new guys have them to get them up and running with battlesystems.

regards pete
