The 2026 Heartland Model Car Nationals will be the 34th show put on by the KC Slammers Model Car Club based in Kansas City, KS. Our 2025 show had 40 display tables of models with over 70 entrants and 87 vendor tables with tons of model car kits, aftermarket parts, tools, etc. for sale. We have 28 separate classes and 15 Master Awards, including the Heartland Champion award. The Overland Park Convention Center, Overland Park, KS is a great venue with plenty of parking, nearby restaurants and lodging. We create a PowerPoint-based awards show with photos of the Class winning and Master Award winning models along with the entrant's name and class sponsor. It is simply a great show put on by fellow car modelers and we even have a class called "Military (automotive related)…any non-track, automotive-style vehicle used by any military force from any nation." for our fellow military modelers. Our 2026 theme is "TRUCKS" Here’s the scoop on this theme. All kinds of trucks from mini-pickups to Dump Trucks, Monster Trucks, Semis, all kinds of Pickups, Kustom Trucks, Show Trucks and  YOU NAME IT! If it’s a truck, build it and bring it to our 34th Heartland Show and bring it to the BEST Model Car Show in the Midwest, almost dead center in the middle of the U.S. If you haven’t been to a Heartland Model Car Nationals you just haven’t been to the best model car show in the U.S. We work very hard to put this show on and it’s an “all-hands-on-deck” operation. We hope you’ll join us. YOU DON’T WANT TO MISS THIS ONE!
