"tire split Difference between front and rear tire diameters)
- is pretty useful for tuning steering characteristics.
Larger split - more rear grip, less turn in.
Closer split - more turn in, free rear end.
2 - 3mm of split should be a pretty common number."

has anyone tried using speed power's 6000mah 65C 1S battery?....anyfeed back much appreciated tnx in advance.

I was wondering if a 35 amp hobbywing xerun would work in 1/12 for 13.5 no boost (1cell)? I'm looking for a cheap esc I can put in the 1/12, but also use in my SC truck if I need to. Any input is appreciated.

All I can say is, Awesome!!!!!!!! Very nice lipos indeed and you cant beat the price if buying direct off the Speedpower website.

well after 20yrs since i last ran 1, i'm back in the 1:12 game. walked out the store with a 5.1 yesterday along with some trick bits to finish it off. i bought 74T spurs as they were the shortest they had but i've heard/seen mentions to even smaller spurs. there is talk of doin 17.5 during the wk for a more relaxed setup oriented race nite and its gonna require some serious gear. checked nexus, stormer, and ST-no luck. thoughts/info? thx

Ryan,
I'm actually looking for the same info as you, and if I find anything I'll let you know. What else did you get to finish off the 5.1? I'll be running one at MRH as well... Currently looking for a 13.5 setup (Cirtix is what they have, so I think I'm gonna go that way since there is no boost). Just trying to figure out what else may help.

Guys, check out Jason @ BMI.....he should have you covered. Or PRS (Precision Racing Systems). Both have top-shelf stuff.

You really shouldn't need anything smaller than that (I'm assuming 17.5 blinky) a roll out of 4.0 should be ruffly what you need and I can get that with a 76 spur 58 pinion and 1.69 tires (smaller pinion if you run bigger tires). Theirs really no need for a smaller spur.

The new CRC spur gears are great! Lots of diff holes for an even smoother diff. Though with the smaller diff ball you will need to space your axle to compensate. Their gears go down to 72T.

reading the instructions for my 12r5.1 in anticipation of goin home and buildin her 2nite. however i noticed it says the supplied servo saver is an airtronics. well i use futaba. in the picture it doesnt look like a SS with inserts-just a standard kimbrough-esque unit. so does that mean i have to go to the hobby store and pick up a futaba servo saver? kinda dumb move there if thats the case.

Yep. They designed the car with servo mount spacing for a Futaba, then include the horn for an Airtronics..

"Back in the day" the preferred servo in 1/12th scale was the Airtronics 94145 servo. So most of the kits from that time forward were and are often still designed around that servo. Hence why it comes with an Airtronics servo saver. The servo savers that use an insert are usually too big for 1/12th and have a much stronger spring than what we need for 1/12th.

..and ironically enough, Associated's own servos take a Futaba horn.

(yes, I know they don't make a 12th scale sized servo, but still...)

well back in my day, pan car guys lived and died by the futaba S132H. heck many of them only servo taped them onto the chassis, sometimes with a horn. worst case u snapped the horn or popped ur servo off its tape. but most times w/blocks...the old days.

My younger brother's L4 is still rockin a S132H (hand-me-downs)
