"We became more than just a little excited when we discovered we had complete sets of the original
pen- and-ink drawings of the very first, fixed-gear Model 17 (Staggerwing) Beechcraft from the
master, William Wylam. These are superb collector’s items!"
"The Model 17's unusual wing
configuration—the upper wing inversely staggered behind the lower—and unique shape resulted in
a design that maximized the pilot's visibility while minimizing the aircraft's tendency to stall.
The fabric-covered fuselage was faired (joined so that the external surfaces blended smoothly)
with wood formers (a frame attached to the truss of the fuselage in order to provide the required
aerodynamic shape) and stringers (longitudinal members of the frame of the fuselage, usually continuous
across a number of bulkheads or other points of support; also known as “longerons”). The Staggerwing's
use of retractable landing gear, uncommon at that time, combined with streamlining and reducing
the weight of the materials, produced an aircraft that could achieve a top speed of 201 miles
per hour (323 kilometers per hour) (but with a landing speed of a stall-proof 45 miles per hour
[72 kilometers per hour]), and able to climb at 1,600 feet per minute (488 meters per minute)
to a maximum altitude of 21,500 feet (6,553 meters). " -
