So Circus Hobbies became Horizon Hobby. I didn't know that. Thanks for the "news". Now as to the worst kit......I seem to have built something from almost all the manufactures already listed. Tidewater Hobbies, Top Flight, Great Planes, Berkely, and some from others not yet listed, Cleveland Models, Comet, Carl Goldberg, and Harold Debolt. You know what, they all flew, and I learned something with each build. It was those early 50's print board kits that Trained me to be able to assemble and redesign today's modern ARF's so that they also all fly (and usually stay in one piece, at least while still in the air). So my worst kit ever wasn't a kit but an ARF, several ARFs in fact. CMP 60 size Spitfire (main gear retracts were located aft of the C/G on a taildragger), H-9 giant PT-19 (wing didn't fit in the saddle area), and then there were two different World Models Cubs that had serious wing root issues. Fixed them all and made them fly thanks to those 50's print board kits, because if you can build and fly one of those, you can fix and fly anything!
