Charlie, it would be easy enough to build an FM stereo system for RC out of Radio Shack parts, but you'll never get the boom boom out of a sub woofer that isn't big, with a monster magnet and a lot of amperage. A little speaker is just a tweeter, no matter what you do to it.
But, hmmmm, a scratchy staticky AM station in the old Power Wagon body.....Hmmmmm.
Well, I got my crank back from Racer. That's all I've done really. I ordered the standard shaft clutch nut like a month ago but it's backordered... so who knows when that'll come in. I'll be shipping out engine components next week. I do need to find a CB though...
