Let me try to clarify the whole PBS/PCR thing. First of all, OFNA can be somewhat inconsistant in the way the RTR's and kits are packed, but here is how they were last time I looked.

PBS - Has pivot ball suspension, stand-up servos, plain stamped aluminum shock towers, aluminum bones without universals. The center diff is the 8 gear spider type. The servos and radio are slow and cheesy, the pipe is almost useless. [>:]

PCR - As mentioned earlier, basically a knockoff of the PBS except for the laydown servo which are not needed. [&o]

The two RTR's above are really very entry level and, ok to chase your neighbor's dog or cat with, but not race worthy.

PCR Pro Kit (best bet for the buck and very competative) - Comes with C-hub and pivot ball components for the front suspension. Comes with laydown servo tray and linkage, but the standard one is mounted. Shock towers are CNC aluminum as are the braces, all drivshafts have universals, all diffs are standard 6 gear type. Has quad brakes, chassis is milled out to save weight.
