Keith,
Thanks for the props. I never get tired of hearing how people enjoy the Q12.
Try more sauce on the front tires. Try about 3/8 of the front tire and then try 1/2 and possibly more until you get the result you are after. Also, what front springs are you using? If you are using .020, you may want to try .018.
Glegg is right about the tires. As much as you might hate to true down new tires, you gotta do it to get the car to work right. This is true for any 1/12 car on carpet not just the Q12.
D.P.

purple in front
gray in rear
carpet track using 19 turn.
how do the pink and double pink compounds work?

I use 20 springs, 35 wieght oil and the olive colored center spring. This is on a med to low bite carpet track.
I prefer double pink fronts at my home track.
Good Luck!

I work in inches so fronts should be 1.73 to 1.80 rears 1.83 to 1.88 max!
As far as caster I have one shim infront and one in back!. with a .20 front spring
about 1/4 degree toe out.
Also when you say push in the corners are you saying mid corner to exit. Or at corner entry. If its entry more sauce will help, as will smaller tires.
If its mid corner and exit try more caster like 4. Tires and spring are done lasr as they are drastic changes.
Also quick question is your diff smooth or tight! That will also contribute to a push!

like everyone said those tires are huge.
The front is 173.5
The rear 179.5
I guess I was thinking about tc I don't know.
Toe is set at 1/2 out.
The diff is really smooth I tried it tight and that made it worse.
The car definitly pushes out of the corner. Oh and by the way it is brand new carpet from CRC. We just finished putting it down last week. So that is probably has a little to do with it.

I would strongly recommend double-pink or magenta/cyan front tires for 19 turn if you are dealing with push.

Going to softer tire will make car steer funky and bite very quick. Caster change is more suttle.
You may also let the carpet get some what of a groove built up as this will change the cars handling.

castor is one in front and one in back.
Some of the corners on the track are really good and some the car just slides the front end exiting the corner. I'm going to do some more testing after we close the hobby shop tonight and try a couple of your suggestions.
thanks

put some more weight on the front wheels, move the batteries forward some.
Also are you SURE this isnt driver error? Depending on throttle modulation, and how you enter a corner can make the car seem out of control wiht a nasty push or an over steer. I have been working myself to learn how to drive my car better as the simple act of blipin the throttle too late, or too soon into a corner can cause the car to get all off ballanced

Like clegg mentioned move the batts forward.
I would only go one step forward if necessary. Some guys like more but I like rearward bite!
#355
I would like to fix the problem with other methods than moving the battieries. I would like to keep that weight were it is.
#356
try a 20 thousandths shimm under the front spring It will keep the front strapped down like a limiter and will help the car keep the car flatter and tighter comming out!

I got the PRC kit in hand... WOW.
The 2.5mm chassis is a freaking tank... I am pretty sure I could put this chassis under my Nitro car and it would fair ok
beautiful work on the parts, I am all kinds of excited to get my car all up and running again!! Also all kinds of excited to see people look at the car and go "what is that?!"
