X2 on that. I have the kyosho part on my mod buggy for the past month its got no slop still. The exotek is a backup part now. Also get some rear hubs if your LHS does not carry them that and the rear bulkhead for RM config, some people have had issues with the studs stripping the plastic.

Do you have the rack and arm, or just the rack?

I built an RB6 for myself a few weeks ago and finally got around to testing it. I ran at a small indoor clay track and I was blown away at how well the car worked. Stock setup and not a single option part. I did bend the front hinge pin brace but it was a hard landing.

If the car works as well outdoors as it does indoors I'm pretty sure it will be what I run at the worlds. Still going to stay with the B44 for 4wd.

The rb6 is a sweet ride and very planted out of the box. I am sure it will work well at the worlds. I kinda think the Tebo has a shot this year.

I run both the Kyosho crank arms and rack (UMW701 & UMW702). When i upgraded, I started with fresh steering king pins (LA256), so the entire assembly was tight and will all wear together.

Do you run the exotek rear bulkhead for RM?

Just want to make sure I'm ready. My track doesnt carry K parts.

Apparently Kyosho has decided to rename the UMW701 aluminum steering plate.

Hi,

has anyone tried the AVID TRIAD slipper in mid motor mod on astro/carpet ? What are your experiences ? If not what do the dirt racers say ? Worth the money ?

Thanks.
