Don, I don't care what I do, the insides of my planes look like a bird nested in them!! Joe, I have gotten away with extensions for years in some very big planes without problems then one day my servos started acting sluggish or would start twitching. It would just be corrision or a wire going loose. The most trouble I have seen was at IMAA shows with nice big scale planes. These planes don't get flown very often and do a lot of hanger time. Pilots tend to forget to open them up and pull and clean there servo leads, it's a lot of work sometimes and most of us are just lazy about it. Then the big opening day of the show starts and the plane checks out OK during inspection but all of a sudden in flight glitches start to rear there ugly head and controls quit controling!! It often got real ugly from that point on. It has happened to me more then once but I have caught it on the ground. By soldering my own extensions this is no longer a problem or threat. Seems to happen with the longer leads more often though?? Maybe I will do a photo shoot of extending leads with solder?? I just did it the other day for my new pattern plane.
