41 & 42 mm tire size are high traction/ grip carpet track tire sizes. 44/ 43 will be fine.

Default 13.5 no boost set up

Hey guys,
We've started running 13.5 blinky. Any set up suggestions as far as tire compunds, front and center springs, static castor.
Thanks,
E

Hey Eric,

That's the same class we run out here...I ran the same setup as I ran at the IIC and it worked pretty good. I ran magenta all around with the 0 caster blocks up front. On our track it pushed a little bit so I'm fine tuning it a bit still and will be going to softer front springs and 5* blocks. If your track is high bite it should be a decent starting point.

Raced my Ch12 for the first time and loved it. car was great and from my first run to lasr run i had gain 5 laps and droped 1sec over my top 20 avg. Id been in the amain bump spot if my rookie error ( cut the turn to soon bounced off inside rail and slammed into outside boards and strip spur gear)



I need help im getting the car down but i just dont have the motor down the straights. i have a novak ballastic timing maxed and close roll out to everyone else. so looking at motors im bewteen a revtech or a orion vortex prostock 17.5 blinky class

Magenta's huh, I have that bag o'tires that AOD gave me but they're CRC tires and I'll need to re-shim the rear to try'em out. I have 5• block now. I'll change some things up next time I'm out. This past sunday was the first time I've run since the IIC.

In the CRC shock what weight oil/ spring do you use?

30wt and gold spring. You need two shims on each side of the rear axle for 172mm with the CRC rims.

Yes, It does matter. Make sure the steering block can slide on the kingpin. A loose front end is better than a tight one.

Ok but I didn't know that the guy had a double wishbone ft end vs. the standard reactive castor but your saying loose on both is good?

Thanks

Hey i wanna email jason i need some parts to get my car all ready to go what email is the best one to get up with him.

Also iv done alot of reading today about setup to try and improve my car and im looking into switching my center spring from Blue to Gold. I need the car to have more on power steering. The track has 4 180deg turns and i have to wait much later in the turn to get on the throttle then i see others doing and also feel theres away to speed it up in the turns. Would a Blue to Gold spring switch be a good Idea?????

Also i plan on trying mounting the servo Flat as i see almost 90% of the guys run flat. Would the also help me with steering in the turns??

I have the speed in the straights but i just feel i have to slow down more then others to stay in the groove in the turns...


Also I LOVE MY COPPER HEAD
