I sold off my gold pan RC10 a couple of months ago wich was in great condition and was a runner . It is being raced in vintage races now by the new owner.
Running brushless in it will not be a problem , just make sure you run a stealth tranny in it from an earlier edition which you can still get parts for .

Parts are also not hard to come by for the RC10 on ebay and believe it or not Tower still stocks a limited supply , or did the last time i checked when i had the car .

The Optima / Javelin keep stock , tidy it up and keep it on the shelf You can buy replica Optima bodies if you need to paint up a new one .
