Mike:
The guys over on the Marui Tank Group will be able to help you out without all the negativity. If you go to my website, and look on the Groups & Distributos page, you'll find the link there (I'm not allowed to post the MTG link here due to forum rules)
Here's a direct link to my links page:

A few guys have done that mod, and even after metal track and suspension, you come out with a tank thats has a proper Tx/Rx set and fully proportional controls for less than the base cost of a Tamiya kit alone.
