Hi Sefton,
There is a very good thread on RCracechat, where it states all aerial wire lengths and types.

The wire is just basic wire, but need to check the number of strands of copper through it - its all on the racechat thread. You can check the wire by stripping the plastic and counting, easy.

openning the case (carefully) and resoldering is very easy, so long as you have a soldering iron with one of those point ends.

I re-did all of my KO receivers last year, and they work 100% since.
