Yes put the mediums ones on

Killa B - Here's a link to the production version of the GMK Supply tools. GMK0145 is the complete set of 3 tools, and GMK0146 is the aluminum CNC'ed replacement for the plastic Kyosho wrench. They should be at A Main and other GMK Supply dealers soon - if you can't wait, PM me.

Wish I could have been there! I'm back up at school now, but if you are heading to Motorama, I'll see you there!

When I looked over his car it was pretty much identical to this one.
http://www.petitrc.com/setup/kyosho/...CRC2013011213/

I think he was using .5 hubs, the track was a little slick early on.

I forgot to see if he was still running that 1 mm ackerman spacer though.

My buddy ran this set up on his car and he really liked it

I ran my buggy mid motor at Thunder in Nashville this weekend, and really liked it. Car was very stable and handled the big jumps with ease. Finished 3rd out of 32 buggies, best finish since switching to the Kyosho!

I would like some of those AKA handlebar tires he is running in that setup.

Otherwise, assemble per instructions and use the included M3 slipper nut (5.5mm hex).

The Triad itself comes with an instructions card...and the Kyosho topshaft you bought from them came with another instruction card, find that one and you're golden. I keep mine in my pit box for this very reason.
i'm looking thru everything that came in the box/bags i see no instructions. and i kept it all.

i'd like to see pics if i can or a link to where you found that. i think i know what they're talking about but i don't want to screw this up
