yeah thats the rix gear S III chassis. It was the first attempt at making a low CG maxx based truck. not a bad chassis except its long.. 2.5" longer than stock which is over an inch longer than most .21 extended chassis and it still uses the stock maxx tranny which just does not stand up too well to .21's. bceause of the length racers didn't like it and the low chassis was not favored by those wanting to bash so it didn't catch on but for less than $500 its a great deal! I'd run it and see how you like it if you don't then part it out or sell it outright and probably walk away even or with extra money in your pocket.
