It may be wise to also add the Xray XB9 to this conversation.
I just finished building one. They fixed all the bugs the 808 had. Better shocks, way more suspension travel, adjustabe hinge pin bulkheads, and olde fashioned normal reliable pinion gears. (the direct pinions were sweet and light, but fragile and hard to shim)
