Andre there is really just one hobby shop in the KC area besides the Hobby Town type trinket stores. It's called Hobby Haven. It's not really in KC but a Kansas-side southern burb called Overland Park. ( where my hideout is). They have a website you can google. They don't really have much for CL but they are a Sig dealer and keep small amounts of wood, dope, hardware etc. They DO carry the Byrons fuel I burn in all formulas in gallons. Also have APC and a few other props, glue, wheels,etc.
Unfortunately about all the other shops faded into history. As a kid here I remember nearly a dozen full line hobby shops around the metro. Hobby Haven is actually one of the originals in the area and Bryan the owner is either second or third generation owner of HH. Real nice folks.
