There is always a demand for build videos of our scratch builds and the editing crew just finished the latest build on the J-20. A little lengthy but well worth it, it shows tricks and steps on how to construct the MFJ-20 build done by Colby and Mr. Marshall.
Sir George Cayley, often called the Father of Aeronautics, designed a helicopter powered by a bow-string mechanism with feather blades (similar to the reproduction shown here). Later, he experimented by flying a model with multiple adjustable surfaces, allowing him to understand how every change affected the model’s flight. This model is a ½ scale replica of his original 1804 model. Cayley used the data from these experiments to publish his On Aerial Navigation in 1809.
