Just picked up a Typhon 6s BLX for $50, missing it's wheels and has a bad front dif. The guy I bought it off of said the center dif is locked and he thinks that is why he was having trouble killing the front dif. I'm not new to the hobby but I always stuck with traxxas 2wd's so I feel a bit lost with this, 1st Arrma and 1st 4wd. Any good threads that would be a good guide as far as what to and not to do? I've wasted more than enough money to know not to dive in head first lol.
