Put dumper's setup on my gen-xl and since dropping it down on the track I have not changed a thing has been hooked since day 1. Thanks for posting your setup sheet.
Have noticed a couple of things and was wondering what the best way of tuning them out of the car would be. Run on CRC carpet but the track is bumpy.
1) At the end of the main straight there is a high speed sweeper. The inside right wheel likes to leave the track. (visibly from the drivers stand). Checked the front end and nothing is visibly broken when playing with it. Put a softer center spring in the car and added additional pre-load to the side springs without effect. Any other ideas?
2) I have noticed the front tires like to cone. I have gone up from -.25deg camber to -.50deg and it has gone away slightly but the car has become more edgy. Is this just a case of visiting the tire truer more often to get that same good feeling.

2) Add more camber, if the tires aren't wearing flat, you haven't optimised the front-end geometry, and you're really only using the part of the tire that you're wearing away.
Based on the fact that you feel the car is edgy with your current set-up, I'd start by increasing the tube lube viscosity, and also increasing front-camber, the tube lube should settle the car down to compensate for your increase in camber. If after making these changes it's still lifting, try a stiffer front spring.

Gas god.
Would there be an experienced racer at you're local track that could help you build the car? I hate to see people thrashing the Co. only to find out that they were wrong. ie servo not being centered...ie not having servo mounted correctly to fit speedo...
If you spent an eighth of the amount of time practicing that you spend complaining and calling out CRC you would be much better off.

Who's makin a fuss-- I asked a simple question-- A
I never said I didn't like the car
Thanks Dumper and Crashby for the civil advice.

I got to run mine last wknd and. Boy, its been at least 8 years since I last ran rc and I must confess that with these new chassis, batteries and electronics the game has changed. You are no longer chassing power, there is soo much torque with these new BL motors. All I need to do is concentrate on chassis setup. What a beautiful thing!
I built mine box stock except for shimming the Futaba 9650 fwd by 2mm to accomodate a center mount KO VFS-1 v1.5 speedy. Everything is centered pretty nice and tight.
The car components were all tweak free, straight out of the box. High quality plastic moldings, beaitfull CNC aluminum, and precise cut CF parts.
The new shocks are sick! No fuss easy to build and super smooth. Marvelous little gems. The diffs, man oh man, glass smooth.
Glad I am back to racing 1/12 with a CRC design. I debated over getting a AE T-bar car, since I figure I been so long that trailing arms would be hard, but no regrets now.

thanks for the advise! The car did not lift after changing up from 5k to 10k in the tubes.
Rotated the fronts as the LF was coning badly. After the change the LF is no longer loading as hard and is coning about at the same rate as the right.
Will toss the tires through the truer tonight to reset them. I will take 1/4 to 1/2 turn of preload out of the rear springs and go up from -.50deg to -1deg to remove the coning.

Need some suggestions for a car stand for my Gen-XL and my Gen-X10. I remember Trinity used to make a 1/12th scale hard foam car stand years ago. I have a Much More aluminum stand that had foam strips on top that are not grippy at all. I also have a Duratrax spinning car stand. I do not like either of them size or grip-wise for the 1/12th scale. Any suggestions guys?

On the weekend i placed 2nd at the Australian Nationals with the new car. It was very good, and considering i didnt even test it before the event it was very easy to set up. The car also works very well on asphalt. I think this car carries more corner speed than the old car. In case anyone was wondering i was using a 5000 40c intellect lipo with a 4.0 motor and booster. Made runtime pretty well. Only time i dumped was when the weather was at 42-46c(Air temp) Batteries were puffing up 
The car who came 1st was using Nimh.
All in all this car is very good and I look forward to running with it more.

I added coments to the areas I run different from you in 17.5. My car turns very well and is consistant the whole run.
If you need corner speed and drive very aggressively try this setup. I may go from full to 3/4 throttle and that's it. This setup will be used at the Holloween Classic this weekend.

What does lubing the king pins do for the handling of the car?
I'm very new to RC racing and this seems to be a trick I haven't heard of yet?
Any help would be appreciated..

Heavy lube on the front kingpins acts like dampening on your front suspension. Helps smooth out the car in the corners. Kinda messy tho, and you have to keep re-doing it every so often.
