Did my normal flattening and straightening and set up for a new chassis. Ran like a t**d. Took it all apart and spent close to an hour to get the pans flat and straight again. -- it's very bendy.. Runs way better, but haven't really thrashed with it yet to see if it holds or bends/warps. It also takes serious grinding on the too-small oilite holes.

The Oillite holes are undersized by design to provide a pilot to align the axle accurately in the chassis. It takes more time to load the reamer into the Dremel than to size and align the holes. Likely you didn’t read the chassis instruction sheet located on the website. hmm, Blue & Orange says it all. https://kcracing.net...ing - Rev A.pdf

I" have a couple of these and after straightening they handled great!! BUT---the material is NOT as strong as the JK chassis---easily bendy--so I've gone to using the center section only and the JK Aolis chassis side pans fit fine. It really helps because the KC material is just too soft and bendy.

don't think you can hardened 304 by heat treating, but peening may work

Are these sold through a distributor and tracks, or are they online only?
The Voltan is not listed on the ERI or Eagle websites.
The KCRacing website has a link for track owners to click on. If you click on the link it says:
"If you are a stocking track owner we have a competitive program for you to offer KC Racing products. Please complete the form on this page and we will get in touch with you."

304 grade Stainless can not be hardened by heat treating. It can be cryogenetically hardened in nitrogen gas, but that is an expensive process, not something for slot car chassis. The higher number of 300 class stainless, such as 310 to 312, is naturally hard enough for a flexi chassis and still be flexible. For heat treatment, you need to go into the 400 class stainless, which is used for knife blades and such.
I have a question. Why do the bushing holes have to be align reamed?

I bought my chassis directly from the KC website. Simply ordered motors, ESC's and motor adapters for older flexi chassis as well as the KC brushless chassis. Their very easy to deal with -- good service and response to any questions.

I've had mine for a while and feel it handles really well, on par with any JK or Mossetti chassis I run. The material is too soft, similar to the newer Mid-America chassis, bends too easily.

Reamed the holes
Uprights aren't vertical
As you can see by the axle misalignment, the uprights are leaning outwards
The motor mount is not vertical either
On https://kcracing.net/About-us/ it says, in part:
"We are committed to designing and manufacturing slot car chassis and accessories that exceed the expectations of our customers..."
I personally feel that causing their customers to have to finish the chassis forming process is falling short of "exceed the expectations".
I would even prefer paying a few dollars more for the chassis if the forming was complete.

sorry, but all flexi chassis have to be flatten & tweaked to some degree.

True. There is always some spring-back in the forming process. But the tool can be designed to correct this. It is not easy to bend the uprights to perfect 90o by hand. If you have to open the bushing holes, might as well punch them a little oversize to begin with.
The motor bracket is even tougher yet. You need a tiny machinists square to check it. Like the ones from SPI. The smallest one is 1 inch long along the longest leg, just right for checking the bracket.

I got a small machinist square somewhere for less than $10. Perhaps not the diemaker's accuracy of the SPIs, but it has worked well when I ran a flexi from '96-2010. It probably came from Micromark or Campbell Tools when they were in KY.
I intend to live forever! So far, so good.
