Great stuff, fast shipping, etc. I've had several good experiences ordering from them directly. Their gears are among the best.

Attention Capelracer...
The Eagle has landed, I say again, the Eagle HAS landed.

I also have no idea what rollout to start with for this car. The track is a smaller Carpet track. Usually pretty tight. With 12th scale we would typically run a 2.2" to 2.5" rollout with the 13.5.

I'd start that 13.5 around the 1.20 range for Pit Road. Down at the WoHaG you need to be around a 1.30 - 1.35.
In 12th scale those guys were running about the same roll out you are running at Pit Road.

Just to clarify slide the height gage under the wheel that is being held up, and the surface of the set-up board. By adjusting the up travel screw you change the amount the arm is allowed to lift, or travel up. There is a bit of "feel" to this method.
I started with the old JRX-S standard setting of 2mm of up travel. This is using the set-up board surface as zero which the chassis is set pressed flat to.
Obviously their are better ways of doing this. Set-up wheels would eliminate any discrepancy due to the pliability of the tires. Another method if you have blocks available of the right thickness is put them underneath the tires while the chassis is pushed flat and adjust the up travel screws and go by the feel of the chassis as it tries to rise. And of course feel free to remove the shocks based on your preference and time available.
Confused yet?

Edit for some more clarification. Again this is for up-travel. Technically yes, droop screws adjust up-travel of the chassis from ride height. But I understand him to mean the actual up travel screws which are in the sway bar mounts which control the up-travel of the arms in relation to the chassis. For instance if we consider droop the amount of lift, or up-travel the chassis has from ride height, up travel would control the amount of drop the chassis has from ride height. So if 2mm of droop (at 4mm ride height) means that if the chassis is lifted the wheels will leave the ground at 6mm, then 2mm of up travel....er......down travel???.... would mean that if the tires were supported independitly that the chassis would dip 2mm below the zero surface of the tires contact patch, or again 6mm of chassis travel from ride height.
Basically bump stops to put it simply, and bluntly.
I mainly have found it to be a powerful tool in combating traction rolling. When the chassis rolls to much and the inside wheel begins to lift the outside is caught by the up travel screw creating a long, rigid arm that extends from the wheel contact patch to the other side of the chassis stopping a traction roll through leverage on the center of mass. I'm sure it has other uses but I am still trying to rack my brain around them. In dirt they are so much more obvious do to the huge amounts of travel and the fact that the tires leave the surface much more often.
Another use is if the chassis is "digging" in the corners. E.g. there is a bunch of tire rubber on the chassis from the chassis actually hitting the surface in a hard corner. This could be counter acted by not allowing the chassis to dip into the ground by hitting the hard stop of the up travel screws. But be warned this can sometimes cause things to be a bit erratic, at least from my experience in the the full size arena.

Others have mentioned the kit setup pushes (foams) and I had the same experience. I tried going to a normal camber link up front without much change. I don't have any tuning parts to try yet, but if you've got some suggestions on how to get more steering with the stock parts, that would be cool.
The car was extremely smooth and fast, and carried a lot of corner speed. I just struggled with it being a little slow to turn in, and pushing quite a bit exiting the turns on power. I don't know how much the light LiPo might have affected this, but one of the guys I race with (smoke81) is working on a solution for that. I imagine he'll post here about his progress. The car is currently 46.8oz w/o the body. :-D

A little fyi for everyone, at most of the races this past season we use double pink orange fronts and double pink rears. We even used this at Vegas and we had one of the best cars at the event. I am not really sold on the double pinks all around. At the ROAR Nats, we did use single stage double pinks and ran well for the first time however we did glue the front outer side wall above the sidewall. For some reason the Type R does not need the ultra aggressive front tire like other cars. For the most part we did not like the 26mm tires on high bite as it would make the car lift in the middle of the turn.
