Regarding tight in and loose off... What I've seen quite often on carpet is that with a really pushy car, you can use too much steering throw and force the car to turn, but it's all bound up. Then when you get on the power you've still got the wheels turned too much, the front digs in hard, and the car doesn't want to straighten out, seeming like oversteer. Making the usual changes to tighten up the car then makes it worse. Changing the setup towards more steering can actually solve it.
But of course as Paul mentioned, if your rear diff is bound up, that can make it kick out. Also if the rear belt is too tight relative to the front, that can make the rear kick out when you get on power, too.

It is his first time driving with a spool. I am sure that is a learning experience for him.

A found a comment by another racer made in the 1/12 scale thread. No one managed to answer his question. I too am curios to find out what your opinion is.
"Just out of curiosity...
Suppose I'm running maximum caster at my front end (all 3 shims to the front) and 5* Blocks.
What would be the difference between:
moving a shim to the rear...
or changing to 10* caster block
I already know the reactive caster allows you to have more in the straights, calming the car, and less in the corner, allowing the car to turn in harder.
I just want to know under what situations would it be better to make static caster changes vs. reactive caster changes."
Cheers.

This set up was good for me on carpet.

I Haven't played with brakes yet but i suppose go to 100% brake on the speedo settings for starters.

Thanks again Paul for the tuning help at the Nats! Your sponsors could not have a better rep. That was an unbelievable show of driving talent as well.
My son is definitely a new fan. I'm glad he has a good role model. Get some more Gravity Products out there so we can show some appreciation that way as well!
Augie and I look forward to racing with you again. We sure wish Colorado was possible for us. Sounds like a blast!
