The F.S. 3 glider designed and built by Ferdinand Schulz was also nicknamed Besenstielkiste and "Besenstiel". Although numerous records were flown with this aircraft, it retained its nickname. In 1922 - like the FS2 in 1921 - it was not approved by the Technical Commission (Teko) in the Rhön competition due to insufficient structural strength.
construction
The braced high-wing aircraft has a two-spar wing with a Joukowski profile modified by Schulz . The tail girder is formed by two spars one above the other. The cell of the FS3 was made exclusively from pine trees and door hinges, the covering consisted of old army duvet covers and the control was carried out via two rudder flaps similar to table tennis bats on the wing ends.
World record
On May 11, 1924, Ferdinand Schulz stayed in the air during the second German coastal flight competition on the Curonian Spit with his "broomstick box" for 8 hours and 42 minutes using the upward wind , setting a world record.
