Vic's low $$ build off, rc10 Rock Crawler ?!?!

i hope this counts, the concept started long ago but never really got off the ground. this low buck build off was the perfect excuse to waste some time throwing this wonderful gem together !!!! the body is an old terrible condition botched paint job body that came on a bay purchased RC10, i believe it was on the chassis i used for this build too. i didnt think too much about cutting it up to fit the MSC over on the side all wacky. the wing is from a b3 i think, one of my 1st paint jobs. i used the wrong white paint.
yes, that is a vintage futaba conquest, the only radio i have with more than 2 channels. found the radio + half of an old gas plane with receiver and servos in the garbage. the battery is mounted on top, up front to get some weight up in the front of this machine, also, adds to the aesthetic quality.
i needed the extra channel for the 4 wheel steering !
i suppose by now you might be wondering what on earth i was thinking, and maybe noticed that strange transmission set up hiding back there ?
You guessed it !!! Home made gear reduction !
see that fancy steel spur gear ? its actually a gear from a mid 90's computer printer !
its secured to the stock associated transmission brace with a random hinge pin from some forgotten RC car. the soft aluminum obviously isnt strong enough for such a modification, so i made this steel ''brace'' of sorts. on the back of the printer gear is an old steel pinion gear, silver soldered in place to mesh up with the stock associated spur to create my underdrive ratio. so the fancy printer gear/pinion combo acts as an idler. ( i have not yet determined the exact ratio, but the car moves about 1/10th of the speed )
closer inspection of the printer idler and the transmission brace :
