Alright, it's probably been mentioned somewhere but my searching and reading through 800 pages is getting old. My question is about the Jaco 2-stage tire compounds. What is the difference between the Yellow and Double Pink rears and how does the Black front tire differ from the rest of the fronts?

As far as ESC's go, which model is most popular? My VFS Pro is going bad and I want to get a different ESC. I'm thinking of going with the GTB 4-Cell. Is there a cheaper alternative that is as good as the GTB or better for the price?

Thanks

the inner core foam on the rim is firmer on a Dbl pink rear. the yellow 2stg rear has a softer core. as for the actual racing compound of a yellow, i have heard they are whites or dbl pinks.

black exotic compund are close to purples in shore rating, black compounds are used on hi-bite carpet tracks for consistent traction and feel. in some conditions purple tend to get gripier as the race progresses.

Based on that, what would you recommend for high bite indoor asphalt, like the nationals at PIR?

We have similar bite at SIR also indoor asphalt just no VHT application in the past. We run Pink or x2 Pink. All depends on your steering choice. The DP will have a little more bite but is also a little freer in the turns. For front we usually run Purple I have messed around with DP fronts but never spent alot of setup time with it on the car. My personal pref for SIR is Jaco DP rear with Parma Pur front.

Wait...so double pink has more grip then regular pink? What do you mean by free'er in the turns?

By freer it would be harder, the back end would be "looser". 2xPink is harder than Pink.

How would it have more grip then? To me looser means less grip.

pink has more grip than 2xpink

i normally run (and should stay to this ) purple pink

but on high bite black pink, this is crc tires

Ok that's what I thought...I was just confused by what Diffuser said that double pink had more bite which didn't make sense to me. I've been running purple/pink forever but now our track is a lot more high bite then we are used to and the car is getting loose as the day wears on so I think I'll try black/pink.

but if you are a prity good drive (i am not) you may want to try magenta in the front and see what happens

oh and blacks dope the whole tire.

Once I get a new servo in I might try magentas...right now though my 94145 has a lot of play in the gears that makes it not always track straight...quite annoying.

JR makes a very good and cheap servo for 1/12

I like the Futaba S9650's

Yeah...before AE started pre-drilling their chassis for the 94145 I used to run JR 3025 servos in 1/12th scale...they were always great servos. Though this time I'm thinking on going digital.
