With the KC you can run the diff in high or low position the change in height requires a longer outs dive I believe.

The width (4mm) and the pitch are the same and the KC uses the same 20T pulley as the KF2. My guess is that it is just an improved part from the company who makes the belts.

While we are talking about drivetrain, I noticed the idler gear in the new 3-gear setup appears to be plastic. If so, very little if any grease will be needed on these as was necessary on the metal <--> metal mesh of the 2-gear. Easier maintenance and perhaps even quieter. Although mine have never been real noisy some others have mentioned it here before.

Ok guys I got Lunsford to put together some turnbuckles for the KD/KC for us and I have a bunch on the way... they're on the site for a special price for the Schumacher guys. They'll be here in a couple days

Looking at the exploded diagram it looked like U7061 might be plastic because it accepts those flanged bearings. And the manual does not call out the use of grease on the side gears anymore as it did in the KF2 manual. I wonder why that is?

The 3rd round of the EOS series is this weekend and the KC's are doing well. Michal is 2nd overall so far.

Track looks pretty fun. Lots of jumps

Redrc has a ton of pics and video

Hey Tony thanks for replying! I found the issue, the small screw that clamps the core servo arm, well it worked it's self loose! Problem solved.

Great Mel!!!

Incredible drive for Michal. Ha had a bit rough qualifying initially but focused and brought home the win with 2 brilliant main events. He was nearly flawless in both runs. The car looks so smooth and easy to drive when the others were traction rolling and twitching about. The KC is the car to have on carpet no question
