The Woodstock was designed in the late 1970s by Maupin, with assistance from Irv Culver, who designed the airfoil for the wing. Culver's airfoil is of 18% thickness at the root, thinning to 13% thickness at the wing tip and incorporates no washout.
The aircraft's design goals were low cost and simplicity of construction. Four design principles were employed: using the least expensive materials, using as little material as possible, keeping the design simple and utilizing as many common parts as possible. The resulting airframe is all-wood, with the major structural parts fabricated from Douglas fir. The tail and wing covering are birch. The wing and tailplane ribs are made in pairs from marine-grade fir plywood using a bandsaw. The wing spar is a hollow box for the first 81NaN1 from the root and then changes to a "C-section" outboard. Top surface spoilers are provided.
The main landing gear is an 110NaN0 go-cart wheel mounted as a fixed monowheel, with a brake fashioned from aluminium sheet and employed as a band brake, actuated by a bicycle brake lever mounted on the control stick.
The Woodstock won first place in the 1984 Sailplane Homebuilders Association design contest.
In 1998 Gary Osoba won the US Region 9 Sports Class contest in his Woodstock.[3] In April 1998, Osoba earned US National and World Records in the Ultralight Category for Straight Distance, Distance to a Goal, and Distance up to Three Turnpoints for a flight of 340 miles in his Woodstock.[4] In August 2000 Osoba set the US National and World Record for the Ultralight Category for speed around a 1000NaN0 triangle of 52.40NaN0 in his Woodstock. Also in August 2000, Osoba flew his Woodstock to a US National and World Record for Out and Return Distance of 162.090NaN0.[5] In July 2008 Osoba flew his Woodstock on a flight of over 7910NaN0 from Zapata, Texas to northeast of Lubbock, Texas, likely the longest distance flight ever achieved in a Woodstock. The flight was not documented to World Record standards but beat the standing Ultralight Free Distance World Record by nearly 1750NaN0.[6] [7]
In May 2002 Matt Michael established 7 Iowa State Records for Distance to a Declared goal for a flight of 233.810NaN0 in his Woodstock. In May 2003 Michael established 10 Iowa State Records for Triangle Distance and Distance up to 3 Turnpoints for a flight of 252.560NaN0 in his Woodstock. In that same flight, he set the Iowa State Altitude and Altitude Gain records at 112000NaN0 and 84000NaN0, respectively.[8] [9]
