I use Josh Wheelers Worlds setup as a base setup on the BOB.
The only handleing problem I have is a few traction rolls and an understeer that pops up randomly every once in a while.
I had to increase my rear camber to get the car to slide more to prevent the rolls and under steer. (Never had that problem with the RC8, it never had enough traction to traction roll.
)
Droop (-2,-2) and ride ht are critical on the BOB.
The quality of the Xray can really turn you into a snob. Everthing else starts to look like an entry level Duratrax.
