We've been running 4200's and 3.5's for 2 years now. We've run on asphalt and on carpet.
Not a huge step to Lipo.
Just don't run 64 pitch
6 cell and a 3.5? Your a better man than me.

On a link car, what does raising the front link ball do to the hanling of the car. Also what does it do if you raise the back ball also.

Raising the front of the shock gives more weight transfer to the front on-power and tends to provide more on-power steering.

Raising BOTH ends of the shock the same amount only raises the center of gravity because you haven't altered the geometry, you've just pushed it further in the air. A vertical shift through addition of a constant in cartesian coordinate linear equation terms where the line is defined by the axis of your shock.

The links im talking about are the side links that go from the rear pod to the main chassis.

Raising both front and rear of the shock the same amount will move the shock further from the pivot point which gives the shock a softer feel due to the increase in leverage. That is really the only difference. The goemetry is the same and yes it will slightly increase the CG but not much.

The first key is you need to move the pivot height up and down to match what is done with the side links.

The closer to the chassis you are with the links and pivots the lower the roll center, raising them raises the roll center. This can be seen with the pre-3.2R Carpet knives "standard" roll-center vs the accessory "low" roll-center kit (which was standard on the 3.2R and now the Gen-X). Raising the roll center gives more side-to-side weight transfer and aids rear traction in low-medium grip situations. This can lead to traction-rolling as grip increases. Lowering the roll-center decreases this tendency to traction-roll by making shift more laterally at the tire contact patch than pushing down (higher roll-center) so the rear will try to break traction (eventually) and slide rather than bite in.

Can someone tell me if Jaco Prizm wheels are the same diameter as the CRC wheels?

thank you very much

Actually, a 10th pancar is way easier to drive than a 1/12th scale car.
You only need a little throttle control.

I think they're pretty close. Why?

I have CRC tires installed on my gen-x currently. I don't have CRC rear pinks available right now so I'm thinking of putting Prizm pinks on the rear, and dont want to put a different size wheel on to limit the change of variables on my setup. I also heard I have to shim both sides to keep the width the same.

Actually, to answer Smoke's original question. Raising the front of the link creates roll steer by moving the inside wheel forward. This can help with steering in the middle of the corner but can make an already aggressive car very hard to drive. Raising the rear of the link has the opposite effect and is rarely used since the car doesn't want to track correctly in the corner.

I think you'll have to shim it a little, but I'd say any difference in performance based on any minor difference in dia. would be negligible. If your name was Mike Blackstock you MIGHT be able to spot a difference on the clock, mere mortals would never know.

Yeah, I also didnt think that most pan cars are 235mm and mine is 200mm. I can see it being alot more stable for serious HP of the 3.5 and 6 cell. I still dont hink i will ever run it that way.

You don't know what you're missing!
(200mm can be just as at as 235, just needs a good highdownforce body!)

Reedy even higher
OK, so can you give me a good front and rear tire diameter and gearing for an 12L4 using a Orion V2 19T and Jaco tires?
