Sad to have to report that noted slot car personality Jim Hahn of Oklahoma passed away this morning, according to a post made by his daughter less than a hour ago on his Facebook page.
I know a lot of the wing cars guys used Jim's excellent balancing, gear, and other slot car services.
No cause of death was given.
Here's the only decent picture of Jim I could locate quickly, shown with our mutual friend Bernie Schatz on the right.
