Free flight, rubber powered, balsa stick-and-tissue, scale model airplanes: "free flight" means no RC, "rubber powered" means power comes from twisted strands of rubber, "balsa stick-and-tissue" means models are constructed from a frame of balsa wood covered in tissue paper, and "scale" means these ships are miniature replicas of real planes. The premier group for free flight scale is the Flying Aces Club (FAC).
Mechanics of the Leading Edge |
Ever wondered if scientific and engineering principles could help design a stronger leading edge? Look no further for a foray into math, physics, and balsa wood -- with an intriguing outcome. |
Material Properties of Balsa |
Ever wondered what the Young's modulus of balsa is? Your mechanics professor wasn't kidding when he said everything is a spring... |
Retractable Landing Gear RB-1 |
I once made a free flight scale ship with automatic retractable landing gear. The tailskid hooks up to a mechanism that pops the gear up when the plane takes off. The system worked pretty well, and the plane flew, too. Be sure to check out the operating instructions linked in the publication. Alas, the ship was lost on a 6min+ out of sight flight at Durham... |
Laird Solution |
I once decided to try drawing plans "from scratch". I went to the New England Air Museum in CT with a tape measure and a camera, then spent a lot of time at the drawing board. After a bit of time with graph paper, a compass, and a french curve, I had a 3-view. Then I drew the plans with the same implements based on the 3-view. Then, I built the plane from the plans. The resulting ship flew pretty well, but suffered a serious stooge accident (see "Carnage"). |
Scale Spandau Guns |
For my Fokker DVII, I needed scale models of the spandau guns. Here are plans to make your own. They are just right for a 20" span Fokker DVII. |

Lockheed Vega Flight16" wingspan Lockheed Vega in the colors of the ship Amelia Earhart flew solo accross the Atlantic Ocean. Earhart was the first woman and second human (after lindbergh) to accomplish this feat. This flight was at Woodsum Farm in Amesbury. |
