Wow, I can't imagine a wire breaking like that unless it had a strain point in that spot or either was a defective wire from the factory. A number of people replaced the factory wire with a length of servo wire for the gimbals early on. Servo wire is a good bit thicker and so more durable. Yes, it's probably a couple of hours' job to fix it, but with the reliability of Airtronics radios otherwise I think it's worth it.
