[1] The BiCH-16 was a wooden construction tailless design with a braced skid landing gear and the wings moved by pedals.
[1] It was first flown by R.A. Pischuchev as a glider after launch by cable but it was unstable and re-built a number of times before being abandoned in 1938.
The centre of the structure has a landing-spring ski at the bottom and a small keel at the rear.
To fly, the pilot stood upright on the ski, then strapped down with his hands in the controls.
The wing flapping movements were performed by leg power by crouching and then straightening out.
