A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes.
A monoplane has inherently the highest efficiency and lowest drag of any wing confi ...

Design and development
The HP-13 (''HP'' stands for ''high performance'') was a developmental milestone aircraft between the
HP-11 and the later
HP-14
The HP-14 is a Richard Schreder-designed all-metal glider aircraft that was offered as a kit for homebuilding during the 1960s and 1970s. It was originally developed by retrofitting improved wings to the fuselage and tail of the HP-13, and f ...
. The HP-13 was designed by taking the

The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft t ...

An airfoil (American English) or aerofoil (British English) is the cross-sectional shape of an object whose motion through a gas is capable of generating significant lift, such as a wing, a sail, or the blades of propeller, rotor, or turbine.

but extended from the HP-12's
FAI Standard Class span to for the open class. Eight HP-13s were completed.
The HP-13 was later developed into the HP-14 by designing a new fuselage for the wings. The HP-14 was later
type certified in the
United Kingdom, while the HP-13s were all
amateur-built.
Operational history
In April 2011 there were still five HP-13s registered with the
Federal Aviation Administration, all in the ''Experimental - Amateur-built'' category.
