Seeing how this is my first 12 scale ....hows gearing work?......is it the same as F1?

That depends if you are thinking of rubber tire F1 or foam...With foam we go by roll-out rather than straight up gear ratio because the diameter of the tires affects the final gearing traits. With rubber tire F1 some people do roll-out and some people just gear ratio. I think these days most people are using roll-out.

Ya that's what I mean by F1 ...meaning foam tire F1 .. Measuring tire diameter x Pie yadda yadda yadda.....am I still shooting for a roll out in between 5-6

I'm relatively new to this whole 1/12 thing. Someone please post a picture or a diagram or something as to how to cram a Tekin RS Pro, a TQ Booster, a SR3100 Rx, and a PT into one of these things. I know it shouldn't really be a problem, but I'm lost as to where stuff will fit under the body, where I can run wire so it won't tweak the car, and where stuff can sit that it won't come loose and get damaged or get hit.
EDIT: Inline only. Transverse I know I could do it easily.

Last night I ran the car and must say it was very easy to drive and fun...
Now for the questions from a 1/12th newbie (you have been given notice
)....
It worked best with 2.5 of front camber (because I did not have a way to measure or a setup board for 1/12th, someone else did and changed it to 1, and the lap times got slower... I need to at .5.... Interesting...
I also having a mind problem with this (it's me....) but to set pod droop the ball end on the center shock does not screw on, it turns to a point then spins... So not sure how to use this to set the pod drop... maybe the end is just bad...
I also was running 2.5mm front RH, 3.0mm Center and 3.5 Rear... Again, this was me not paying attention. I really thought I had it at 3.5, 3.0 and 3.5....
As we corrected issues, I noticed it got harder to drive and the lap times got slower.... I found this interesting....

Bvoltz, I just jumped in here and read your post. Odd that you had better lap times with 2.5 camber, it should have screwed right into the carpet. But that said, what tire combo? What is your carpet traction like? What's your sauce pattern (full rear - 3/4 inside front?)
You really want to aim for 3.25-3.5mm of r/h. You can rake the chassis (lower at the nose then the tail) if you want to increase steering, but that is a very subtle setting.
Yes, the #4262 ride height shims are for the xti.... Burt wins a CRC sticker!
A little trick, you can use a header card, a business card, anything with a square 90* corner as a camber gauge. Place it along side your front tire and see how much gap you have at the top. 0.040" or 1mm is going to be about -1* of camber. We normally do not run that much.... so use just slightly less.
