RE: Arming switch - advice.
I've seen that video too. It is definitely the arcing causing the problem and not continuous throughput. In a sense, it was my fault for just not replacing them every so often although I wouldn't have expected them to fail with so few "x" amount of flights. It was pretty wierd though because they always "gave out" in the air and most of the time downwind when it was blowing 20 mph. LOL
