From the first batch of kits it seams the parts quality is better and the new shocks are a breeze to build look forward to this car's first run tomorrow.

You coming down for a spin?

I haven't had much luck with the thicker oil in the diff which is why I posted the question to Mr.Crisp..just snaps around to easy maybe not with the spool? Really need a breakdown of effects on handling when running different types of oil. Not sure how it's used as a tunning aid. My car right now is on but I would like to drive it in a little harder. I still have a slight push which is magnified if I drive it in hard and tap the brakes. Plus a little faster transition would be nice which I could probably take care of with shock position.

Until 2012 I really did not play around much with the rear diff oil and always ran a light 800cst to give lots of rotation off power. However since the snowbirds this year I have been eperimenting a lot more with rear diff oil and could slap myself for not doing this sooner. The rear diff oil has a very big impact on balance of the car. I only run a spool, so I don't have any data on running a front diff. What I have found is that on higher grip surfaces, running a thicker oil in the rear diff makes the car more stable going in and better on-power steering. However on lower grip surfaces a thick rear oil tends to make the car loose on entry as well as exit. So for medium to high grip carpet I seem to like betwen 1000 and 1600 cst. For low grip carpet I like 800cst. I have not run the car on aslphalt yet, but I suspect something in the 800cst to 1200cst will be good with the 800 for lower grip and the 1000 to 1200 for higher grip surfaces....but just a guess at this point.

Could you please elaborate a little on this as I've have read it both ways and would be very interested in what your take is.

Also your book says (if I remember correctly) that the length of the link determines when the camber gain happens. Short links, the gain happens quicker but not as much and with long links the gain happens later in the corner but lasts longer. Is this still true ?

Thanks for your time.
Upper link length does affect both camber gain as well as roll center.

A shorter upper link will raise the static roll center very slightly as well as provide more camber gain. The shorter the upper link the less the car rolls or leans, because of the higher roll center, and also the less the roll center high changes as the car leans.

The longer the upper link the more deeply the car rolls or leans, because th RC stays low throughout the roll.

Changing the lower arm inboard link height will have a larger affect on the roll center than changing the upper link inboard height by the same amount. This is why I tend to change the upper link inboard link height rather than the lower arm inboard link height, so that I can make finer adjustments. I will often make just a 0.5mm adjustment on the inboard upper link as even that small adjustment changes the handling. The same 0.5mm change on the lower arm would have an even greater impact on the handling change.

I hope this helps.
Cheers.
Martin.

I ran 1000cst in the back over the weekend, and there was a good amount of traction. I regret not going to at least 1500! The 1000 seems to work well enough on our low bite here in Indy, even with a spool.... I plan to try 2000 the next chance I get.

Hi All,

New bumper brace is in stock now;

http://www.exotekracing.com/s411-car...per-brace-set/


Martin Crisp is kind enough to test a bunch of new top plate designs for Exotek so we should have some feedback for production of new top plates soon

Thanks!

M

Just setting up a S411 for VTA after having no end of dramas with rear end grip using a Sakura Zero and a T2-009, are lipo batteries relatively secure with the stock battery mounts (2 back, 2 side) and tape, most TC's seem to have CF braces which hold the battery on the outside edge, the S411 doesn't.

Any essential spares / weak points?

Get the carbon fiber battery holders for one.

I just ordered the Exotek bumper brace. Keep the upgrades coming Mike and the Exotek team.
I can't say enough about how well my car is handling now thanks to the guys on this forum. Oh and that App setup workbench (gratuitous plug).
Has anyone compared the Exotek chassis to the Serpent chassis the 2.0 and the 2.25 in particular.
Hey Shroder send me your setup you ran last weekend please. I want to peak
at it. You should have my email.

Martin,

How was traction compared to the snowbirds at the Canadian nats? Trying to find a good high bite starting point!
