No-cal Model Rubber Powered Airplane

I should also clarify that "No-Cal" is not just a "toy" airplane, but an official class within the Federation Aeronautique Internationale (FAI) with strict regulations. These include weight limits, materials, and competition rules that distinguish it from other categories like "Peanut Scale" or "Limited Pennyplane." 1. No Cal: An abbreviation for Northern California. In the 1970s and 1980s, a group of modelers in the Sacramento and Bay Area developed a very specific free-flight airplane design for flying in gyms. "No Cal" became the name for this competition class and design style. 2. Rubber Powered: These airplanes do not have electric motors or engines. Instead, they use a single strand of rubber (often many strands woven together) twisted tightly, which turns a propeller, providing thrust. 3. Airplane: These are flyable model airplanes, not just display models. #nocal #rubberpoweredairplane #smarthobby
