Thanks. Yeah, it has plenty of go now... almost too much.

I forgot to mention that the Axial transmission rotates in the opposite direction as the the Tamiya axles. You can flip the axles up-side-down to fix this, but I already had everything built, so I rotated both of the endbells on the motors 180 degrees to reverse their polarity and rotation. The motors also have been converted to P-94 brush hoods with diagonal slotted, high silver, dual shunt brushes, and custom heavy springs to increase their drag brake.
