Last weekend I replaced the V2.0 ESC boards in my V2+ v3.0 with the V2.1 ESC's. After looking at the solder joints for the coax sections, I decided I needed to do better. I'm not flying this until I know I've done my part right. I absolutely cannot find single 18 gauge stranded center conductor coax, except at Mouser, where it's sold in 1000 foot rolls. I ordered three feet from an electronics shop in CA, but they sent me coax with double solid insulated wires for the center conductors. I called them and told them the order was wrong, they complained about the cost of shipping, and sent me a couple of feet of 23 gauge stranded center conductor. Does anyone have any idea where such a simple item can be purchased? Honest to God, I have more than six hours of searching online and phone calls, and haven't been able to find anything.
