I think I've seen that - Kawahara's upper deck. It was selling at my LHS for around 60-65 USD. Anyone have comments on it?
I finally found some screws for the ones missing from the Torque Sensing Diff. I bought this weekend. HPI makes some in 2.6x8mm that fit perfectly except for the fact that they aren't flat-headed. Has anyone tried this diff yet? I'm gonna install it tonight along with a faster and torque-ier steering servo.
