RE: Does anyone know how to lock a rear diff?
you throw it at your dad and say "I SAID FOUR WHEEL DRIVE!! NOBODY DRIFTS WITH 2 WHEEL DRIVE IN RC! IT'S NEXT TO IM-FRIGGIN-POSSIBLE!!! WHAT TYPE OF FATHER ARE YOU? YOU WANNA SEE ME CRY!!!!???? THAT'S WHAT YOU WANT?! NOW TAKE THIS BACK AND GET IT RIGHT BEFORE I KICK YOU IN DA NUTZ!!! RESPEK MY AUTHOR-EH-TAY!!!" Then, when he gets you a useful 4wd chassis, figure out which one it is and get back to us. It's not hard to lock the rear diff, but it won't do you any good with RWD.
