Im going to be running on a outdoor track. Can be grippy or a bit slick depending on how dry it is. Tires will likely be m4 holeshots or bow ties. Ive chosen to run rear motor to start. Is the prefered setup a stick, shorty or saddle packs with rear motor. Also what position is the preffered speedo.

Hey mate check this link

http://www.petitrc.com/setup/kyosho/...ace2013012427/

Best setup for rear motor before I changed to mid. Has pictures for your electronic layout (shortie). I've run this setup a lot with holeshots and suburbs on the rear depending on the grip, I would recommended proline scrub front m3 with white foam or holeshot with white foam on the front, never liked ribs.

Yes I did, I think Kyosho put the silver ones instead, not sure why.

The silver ball studs have longer threads that don't pull out as easy as the original kit ones

I use UM128 in the rear and front bulkhead. I secure the rear with a locknut as well, and I put in a set screw in the hole not used.

I never run the black studs anywhere, not long enough.

That sucks! The new boxes also have a different chassis and a Tebo's WC medal badge.

What's different about the chassis? I don't care about the badge but what parts are different other than bulkhead?
