Re: Tire Question
 

What tire sauce are you running? I've found Trinity Zip Grip to be "maximum bite" on just about any and every pan car tire compound. Just make sure you DO NOT GET the "Zip Grip Free" version.

That and while pink rears worked in David's case, I would say he's the exception, not the rule (sorry, David). However, White Rears will add rear bite every time I've tried them.

Don't groove the rear tires - it will reduce rear bite by effectively creating multiple sidewalls in the tire that will each flex it's own way.

You may also want to look at what body you're running. If you can run a GTP body, that would make an unbelievable difference right off the bat.

For tires, I still say to stay away from Jaco. TRC's are consistent, well trued, and availibe to order at a lot of places. Many people in here have also had good luck with the BSR tires from www.rc4less.com .

We don't have to agree. Mark is far more expierenced racer than I. I did bang my head aginst the wall all last summer with green tires. Went to pink and Walla! Fastest single lap time of the day with an L3 in the stock TC class. I have never tried white, but pink is softer so should grip better. Try em both :)

GTP body makes a HUGE improvment. Go for all the wing you can get legally. My problem was "hooking" or spinning out entering corners. Nothing I could do would bring me the rear traction I needed. I use paragon, but that does not mean its the best. One time in the main, the race director said "GO" and I floored it, spun out and took out anther guy's wheel. Felt like crap for doing that.

Once you are hooked up, you will be able to whoop those TCs.

Good find. Thank you. I don't have any experience with those bodies, but it looks like it should have pretty good down force.

take care

Tire David vs Mark
 

Hi there,

Beware of drag wit too soft tires.

I drive a Corally c10X and tried several tires.
example Corally silverstar is the softes but the grip is less as Corally green.

And the silverstar diameter is going back every run with 2-3mm so your rollout calculating is gone.

So try to run with tires that do give you good grip do not shrink?, but do not hold you back becouse they give to much grip.

Everything should be in balance.

Yeah, we had that "drag problem" with corally's goldstar tires. They didn't wear ugly-fast like the silverstars, but they had some strange effects. When treated with a fair amount off traction compound, they would develop a lot of drag. So much even that when you would enter a corner, your car would slow down dramatically. Really odd! On the other hand, the tires from TRC, Jaco and BSR seem to be firmer than corally's tyres, even with the same color rating, so that wont happen with those tyres.
If you still need more rear traction, try corally green on the rear, you'll be surprised!
Also, don't look at the tires alone: make sure rear ride height is 1mm lower than front and the T-bar is parallel with the main chassis, make the diff as smooth as possible, even let it slip a little bit.
Further, you could make the rear off the car softer; softer springs and lighter oil, no third screw in the T-bar etc.
If all of that doesn't help, have a look at the front end of the car. try heavier springs, increase caster and camber, set some little toe-out, and last but absolutely not least, install harder front tyres. It's always the combination of the tyres that makes for the car's handling!

Corally’s color scale is nowhere near the U.S. one. I had the goldstar rears that came in my C10x when I had that car and they could not have been even 50% as firm as the softest tires sold here in the U.S. (yellow). I put them on the car once in practice and believe me, wow did they slow it down.

However, the difference between Green, White, Pink, etc. on the non-Corally tire scale in rolling resistance, while theoretically existing, is not noticeable on the track so using whatever hooks up best is the way to go.

Now, if you could hook up a car on all purples, you might gain some top-end speed…

FWIW, White is generally around Shore "A" 25-26, Green 27-28, and Pink 29-30 across all brands. What the companies themselves call the shore rating is another thing but I can pick up a White from TRC, Jaco, or BSR and idenitify it as such on feel alone. Same for a Green and Pink.

Yokomo's ZE-RHB should work well for you also.

Was your C10/x equiped with Goldstar tires, Mark?
It normally comes with the cheaper silverstar tires.

Corally's color tires are very usefull, even though they're very soft.
Hey, it's what all the fast guys around here use! Keep in mind though that the climate around here's a lot different from california! We're always low on traction here, since all rubber on the track washes away with the rain. Temperatures here are a lot lower here too!

They had a goldstar sticker stuck to the rim so I would assume that's what they were. I actually got it pretty hooked up on Pink/Pink after a while but still could not overcome the weight issue for stock.

The biggest help will be to run them. You'll find they are simple to maintain and to run (although you will want to slow down your steering - turn down the exponential on your controller). The biggest thing about maintaining them is to keep them in tweak. If they go out (due to a crash, etc.) they're easy to put back in, but very noticeable if they're out. . .

As you can see - you can get a LOT of questions answered on this forum. If you need advice, ask and it shall be answered.

No matter the track, start with Greens all 'round (or maybe pinks in the front) and Zip Grip for sauce (or perhaps Paragon if you can't find Zip). Make sure you're running a GTP style body - Dahms is good, Hotbodies Toyota is good, etc. A GTP style body is attractive and creates the downforce that makes these cars go around corners like a slot-car!!!

But - if you run the cars, people are going to comment on them and that will get them to run with you! Be as friendly as Thirdplace and MarkA and you'll get people to drive with you. Those two pretty much BUILT Pro10 in Southern California - pretty much by just being open and friendly.

You don't need the best speed controller, batteries or motors. MarkA consistently beats everyone running "good" cells, slow steering servo and "okay" stock motors. Thirdplace had always worked to get the top-notch motors and batteries, worked hard to lighten his car to the bare minimum, etc. It gave him an advantage over guys like me (that and he was just a better driver, except when I was "ON". . .rare. . .) but MarkA's driving ability overcame all of those advantages. Smooth driving overcomes batteries and motors. . .:cry: :D

Since you mentioned tweaking. Whats the best method for tweaking all RC cars in general, knowing when to tweak them and how often to.

Hey guys I just got an email from Garry Owen at AE and he says that they have not made a decision on whether or not they will sponsor my event. Any statements I have made to the effect that they have are not true and should be disregarded

As for helping to bring back the 1/10 scale pancar class the companies can help by reintroducing them as a easy ready to run kit. This will attract more customers and when they see how fast they are they will want to race them and the tracks will notice the increase in people wanting to race pan cars and bring back the 1/10 scale pan car class. This is easier said than done and could take 1 to 6 years to work depending on how popular they are.

Shouldn't be that hard to get people interested, look at how popular NASCAR is. If they made a RTR oval and slapped Dale Jr's number on it, people would line up to race with it. Same goes with any driver. What needs to be done is to break the barrier between NASCAR and RC racing that prevents dedicated fans from making scale replicas of their favorite driver's car. All that licenseing crap needs to stop, and the whole thing about "no alcohol" sposored decals, they see it on TV everyday, who cares. If companies like Team Associated, Custom Works, Trinity and the like expanded the RTR market to include NASCAR themed RTR's, your racer turnout would double, easy. (Are the big boys listening?)

Oval? Turn left? Nascar? We're talking Group C and GTP roadcourse here buddy!:D :D :D :D

Just think about how those open cockpit ferari's would look, or that beatifull bentley!
