I know of nobody besides Crown. Call a company called Flight Systems in the US. If they can't do it, they can probably tell you who can. I may be able to give some help if you can tell me what is going wrong with the truck. These cards rarely go bad. I am speaking aboaut the second generation truck with EV 100 motor controllers. The raise/ lower servo card had some resitors that get very hot and sometimes go bad.

If you are working on what is called the first generation truck ( Cable Form motor controllers) , that could be a whole different story. Those trucks are a lot more tempermental.

A lot of these trucks are scrapped because they are worn out. The second generation truck has been out since 88 or 89 I think. Used cards may be another source.

The company is called Flight Systems Industrial Products. www.fsip.biz
