check with robert at KO, but I believe that he said that 2s was fine for ko rx and servos

Better make it CRC.....you can't find the HB shocks:cry:

I presume you are asking about rear tires. Use shims on the axle to set the rear track width. I use both CRC and Jaco tires. More shims are needed for Jaco rears than the CRC because the wheel offset for each is different.

The maximum rear width specified by ROAR is 172 mm. Use the centering hole on the rear pod to make sure each side is equal. A setup board works great for setting the width.

steering
 

My car "stops" in the corners as if it understeers or the overall grip is too high. I have tried everything but maybe is thinking that the steering travel is too much.

I use the Hudy pan car setup system and I have 25% steering travel meassured with this system - can any of you let me know how much the top drivers have?

The cars stops so much as it looks like the speedo uses motor break, but I use 12.5mm rotor and the speedo is set without motor break but a lot of roll.

I have also tried to gear up the motor.

Not enough information here--- what tires? What car? What springs? What caster? What surface are you running on?
Sounds like your bite is WAY TOO HIGH!!!
Don't think your steering is the problem.
FYI
T

Tires are Jaco Pink in the rear and dbl pink front (front side with glue). Car is Xray Link with pretty much standard setup. Carpet flat surface, with medium/high grip. Caster is close to highest.

I need to find approx 0.2 sec compared to the fast guys (lap times are low 10 sec/high 9 sec).

I use CS High grip additive.

what does this mean. ar the king pins leaned all the way back or are the standing straight up?

what to choose?
 

here is a question i would like your opinion too. i'm thinking of trying something different for a chassis. i have ran associated for years and have had great success with them, however i want to try something different.

i am currently torn between the copper12 and the crc, what are some opinions out there, now before you answer please take in mind i dont want to get into the whole this is better (ford vs. gmc) debate. i would like a more detailed answer if you have time please.

to give you some back ground, we run on crc carpet which is laid down indoors over some bumpy asphalt. the surface is not glass smooth. it has some character:lol: but lots of grip!!!!!

please let me know your thoughts in relation to the question and why you think x would be better

thanks again

The new front end on the CH12 is better for bumps, it has the most travel of any pan car as far as I know. The double wishbone design is simply more adjustable and more adaptable. I have not owned a CRC but I do have the CH12 and I can tell you it will take a beating. I have not raced for over 20 years, I just picked up a CH12 this fall and dropped a 13.5 in. Believe me, this thing has been taking a severe beating and doesn't mind one bit.

When I put my ch12 out for the first time it was really hard to drive, You say it is taking a severe beating have you tried the spacers on the front end that jason had made up. He done some testing and figured out a way to settle the car down alot and he ended up with his best lap times when he done so. I would look into that if i was you so you dont have to continue testing the durability lol. My son and I ended up going back to the gen xl before jason came up with a way to settle the car down. out of the box the crc is alot easier to drive and the ch12 is very aggressive and edgy. It is a really nice car and great build.

With our new front end there is alot of adjustment that you have to tune to different traction conditions. As with any 1/12th car, if the setup isnt right, it will be very edgy and hard to drive. I have helped guys tune there CRC, SpeedMerchant,AE,and X Ray 1/12th cars that were having nothing but hard times. What i always find is the setup is off or something is drastically wrong. All of the cars including ours handle exceptionally well when set up right. Flip side is they can be an absolute handfull if they are wrong.

Our double wishbone suspension is different than what you see available on other cars. It has alot more adjustment and can be fine tuned as you can adjust rollcenter, camber gain, static caster, static camber,droop,track width,and also adjust ride height without shimming the arms. Tire wear is much better also as the tires do not scrub like they do on a strut front end. All of the parts are machined with exception to the upper arm and steering blocks which are injection molded. There is no filing or reaming needed. It goes together just right.

As far as handling goes, Our car works extremely well as does the CRC car. The choice of car isnt going to make you win or lose as they are all high end race cars. It will come down to which one you like better to be honest. Some people like that the CRC car is more common at there local track so they go with that one. Some people like the quality, adjustability, and durability of our car so they go with ours. Its all personal preference. One way or another, if you get any of the cars set up correctly, you will be happy with anything out there. They are all great cars.:cool:

Got a question about RX packs in our cars. With these packs we normally have to run with the on/off switch of the esc in the OFF position. No one really explained to me....THE WHY. What happens if the esc is turned on? My last race day (Wednesday), I ran my car like this in the last Qual & Main. Believe me, it wasn't done on purpose. Could this be the reason why my car felt like a turd speedwise?

Can't say if it made you slow, but I can promise you your built in BEC in the speed control is toast. Whether there was collateral damage to the rest of the ESC, I can't say. Sorry.

i think the answer depends on which ESC. (and i know with tekin RS software, v198 or before?)

with the current tekin software, you can turn on the speedo or not, there should be no performance impact. however if you turn on the speedo then the volage cuttoff will be operable. (not a high priority for me, so i never bother turning on the speedo switch) either way, it is hard to see how switch's on vs off position would impact runtime performance

Are you sure about that? Talking to a Tekin rep, he says it doesn't do any damage to the esc....just bogs it down for some reason:weird::confused:
