2. Three-surface aircraft - Wikipedia

   en.wikipedia.org/wiki/Three-surface_aircraft

   The central wing surface always provides lift and is usually the largest, while the functions of the fore and aft planes may vary between types and may include lift, control and/or stability. In civil aircraft the three surface configuration may be used to give safe stalling characteristics and short takeoff and landing (STOL) performance. It ...

3. Fore-and-aft rig - Wikipedia

   en.wikipedia.org/wiki/Fore-and-aft_rig

   Fore-and-aft rigs include: Rigs with one mast: the proa, the catboat, the sloop, the cutter; Rigs with two masts: the ketch, the yawl; Rigs with two or more masts: the schooner; Barques and barquentines are partially square rigged and partially fore-and-aft rigged. A rig which combines both on a foremast is known as a hermaphroditic rig.

4. Marske Pioneer - Wikipedia

   en.wikipedia.org/wiki/Marske_Pioneer

   Starting in 1972 the Pioneer II was made available as plans or as a kit. The kit included a pre-made fiberglass fuselage shell. Reported building times range from 600 to 2000 hours. At least one Pioneer II was modified with a 45.93 ft (14.0 m) wingspan. [2] [3] Marske has built a prototype Pioneer III, an all-composite variant of the basic design.

5. Rigging - Wikipedia

   en.wikipedia.org/wiki/Rigging

   Most fore-and-aft rigged vessels have the following types of standing rigging: a forestay, a backstay, and upper and lower shrouds (side stays). Less common rigging configurations are diamond stays and jumpers. Both of these are used to keep a thin mast in column especially under the load of a large down wind sail or in strong wind.

6. Greenwood Witch - Wikipedia

   en.wikipedia.org/wiki/Greenwood_Witch

   Its 30 ft (9.1 m) span wing is supported by a single lift strut per side, with jury struts, and incorporates a unique folding mechanism. The wing folds by first hinging the outer panels onto the inner panels and then the whole wing pivots on a central steel post to allow positioning fore-and-aft for towing on its landing gear or for storage.

7. Canard (aeronautics) - Wikipedia

   en.wikipedia.org/wiki/Canard_(aeronautics)

   Some, including the Wrights, experimented with both fore and aft planes on the same aircraft, now known as the three surface configuration. After 1911, few canard types would be produced for many decades. In 1914 W.E. Evans commented that "the Canard type model has practically received its death-blow so far as scientific models are concerned." [12]
