Slash 4x4 Buggy 1717 6s

Hi Lizard, how's it going? Got the ESC working properly now?

Could you do me a favor and measure the base part (outer diameter and length) of that 8mm bore mod 1 Kershaw pinion you have please? I'm wondering what diameter "motor mount hole" those pinions would require to work properly.

I decided get a Kyosho GT2 to put the Turnigy 5682 in (I know... GTs suck in real world, but I'll figure that out how to deal with that later :)) and am looking what gearing options there are. I would need around ~50/34 (pinion/spur) gearing to gear for ~100mph... I will probably replace the center diff with a spool with Revo spur, but pinion is still a bit of a question. Kershaw has these huge 48, 53 and 60T pinions, but they're going to be very heavy, and I think I would want to try a plastic pinion first given those sizes; the standard Revo spur-to-pinion adapters could work, but those Revo spurs come in 40T max I think. Might see if I can get an adapter for some standard 4-screw spurs, or 1st speed nitro gears as sold here on RCM. A spur-to-pinion adapter for the XO-1 spurs would be cool too, but I don't know really how feasible that is. Don't you have the same problem finding pinions for your XO-1 with the Turnigy motor, or are you going to run 8S on it?

Cheers!

EDIT:
Sorry to clutter your thread Lizard, but I know you have one and are likely able to help me out :). Do you know the diameter of the center hole of the XO-1 "cush drive key"? Wondering if it can be used to have XO-1 spurs as pinion, with the added bonus of having "Cush Drive": http://www.rc-monster.com/forum/showthread.php?t=32150
