The 1-7, which first flew in 1937, was the first Schweizer design of which more than one ship was produced making it their first production model.
Design of the 1-7 is based upon the old reliable 1-3 nicknamed the "brick", and brought up to date with metal fuselage and metal wings. This aircraft also set the future of Schweizer Aircraft by providing an archetype to design of the 1-19 and 2-22 and others.
Among the many distinctions of the 1-7 are that it is the smallest and lightest of all of the sailplanes by Schweizer. Increase in weight from a light to heavy pilot would increase the wing loading from three to four pounds per square foot. The 1-7 is also noteworthy for having the first high aspect ratio wings and having the been the first more than one of kind model.
The original 1-7 constructed for the Hudson Valley Soaring Club was requisitioned by the Air Force and subsequently destroyed on the ground by rough weather. The second was sold into private hands. At this time, the country was still in the throws of a depression and no further orders were received, but the second aircraft has now been completely restored to flying condition and has been flown at Elmyra at Vintage Sailplane Association annul gathering and is now at the National Soaring Museum.
