" "experienced""
Thanks, Tom. You could have said "one of those old farts" :-))))))))))
and yes I do remember black wire disease, but never related to servos. I am still flying some of my original Futaba 148's without qualm. That having been said, I gave an electric Grumann Albatross to my son, and early in its life with him, the battery pack failed in flight. The post mortem showed that the BLACK wire had oxidized all the way through the run.
