OK, I got the Ten-T all done up. Went with the Tekin RX8 system (1900kv buggy motor) on 4s 5000mAh Turnigy's, and 20T 32p pinion. The fan on the ESC didn't work out of the box, but upon closer inspection, the red wire was pulled out of the solder joint - nothing a little soldering didn't fix.
Anyway, here are the pics of it all complete:
Drove it around in the basement and am pretty impressed. Sensored works wonderfully at low speed, and brakes are smoother. The buggy motor has
plenty of power for this vehicle.
