I have passed xrays, serpents, tamiyas, and associated cars. The driver and how the car is setup, makes a world of difference.

Amen. The other day I was able to run low 12 second laps with mine and I handed the control over to our local ace and he set fast lap with it! It's all about setup and running a good smooth line and hitting your marks.

Well. I would love to copy a good setup.
My car kept rolling over???

Are you guys running the stock shocks and springs?
What about shock oil?

Thanks,

I have my setup posted on page 37 of this thread. I can re-post if necessary.

I believe you asked us this exact same question a month ago too.

I tried copying your setup but the image is kinda blurry

Also, I fail to see how a floating servo mount is better?

I drilled another hole on the inboard servo mount so now my servo has 3 screws holding it and its not going anywhere.

Is is to prevent servo flex?

How much tire sauce do you put on? If you are rolling over, try putting none in the front, and only on the back wheels. An understeering car is better than an upside down car.

The floating servo allows your car to fully flex, without any distortion (if you intend to setup your car to flex). This is because there is only a single hard-point from your chassis to the servo, as opposed to two hardpoints. By drilling a 3rd hole, you have made another hardpoint, which will stiffen your car and make it less responsive to suspension changes that involve flex.

Some cars are tuned to be stiff as a board, and have your suspension and tires solely responsible for traction. Others are tuned with the above, plus chassis flex to add a third variable. If you want to tune your car without chassis flex, then drilling a 3rd hole to stiffen your servo won't hurt it, and a floating servo mount will be of zero use to you.

Thanks for the lengthy answer but are you saying that I can tune this car to be stiff? That would be with an aluminum chassis right?
I guess its worth trying the floating servo mount then because I am keeping the upgrades at a bare minimum.
The upper bulkhead cover is a part I might get in aluminum cause my ball links are starting to strip out.
I noticed that RCMart has #SAK-U114/PK/V2 but it does not come with the needed spacer with the 2 pins. Where do you get those?
Since I bought Kamloopers XI, I already have:
-Alu BLKHDS
-ALU steering linkage

Would it be too much trouble to repost your setup with better resolution? I tried downloading it again and it's still very blurry

I have to say though, even with my setup issues, I am having so much fun racing this car!!! Much more fun than racing 1/8 nitro!!!!!!!!!!!!!!!!

This chassis (Xi) was made for flex. A stiffer chassis option from Sakura would be the Zero.

I'll get around to re-posting this week.

From your setup sheet, I can barely read 3 racing for your springs.
Are you referring to these ones:

The #7 isn't actually in the set. I got the #7's with the 3racing Tamiya mini aluminum shocks.

There is many alternatives to this set, but this is what I use. Another similar alternative would be Tamiya yellow in the front and Tamiya red in the back.

I use the same setup for 17.5 stock and 21.5 VTA.

The only major difference other than tires (32 sweep WCICS spec tire vs HPI vta tread D compound) is the amount of SXT on the front tires. Full for low grip carpet, none for high grip carpet. Half or quarter for anything in between.

I also run a 2 degree RR block in VTA, as the HPI rear tires are so fat and wide. 3 degree RR block in the TC stock for more stability.

People who have driven my car say that it is smooth and very predictable. Looks like I'm going to have some downtime at the office. Let me see if I can repost a more visible photo.
