My futaba's wire was broken on impact about six inches from the rx case. I was told on another forum to just solder a new piece on and make sure it is 39 inches from the case to the end. It cost somethind like $39 bucks to have a new wire installed if you send it back. That with shipping costs makes no sense to me. For a few bucks more just buy a new one. I'm gonna repair mine and then check it out good with the engine running. We fly at a field of about 50 acres so I have plenty of room to check it without taking off.
