The Explorer PG-1 Aqua Glider is an American single seat, biplane glider that was designed by Bill Skiliar in 1959 and made available as plans for amateur construction. The prototype was built with help from a troop of Air Explorer Scouts that same year.〔Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 40. Soaring Society of America November 1983. USPS 499-920〕〔EAA AirVenture Museum, 2011, ''Skiliar Aqua Glider “Explorer” – N6498D'' ==Design and development== Skiliar was a Colonel in the USAF and an aeronautical engineer and test pilot. He designed the Aqua Glider to be towed behind a boat, taking off from the water, releasing the tow rope and then gliding to a landing on the water.〔〔〔 The Aqua Glider is made from wood and covered with doped aircraft fabric. The landing gear is fixed and consists of a pair of water skis. The aircraft uses spoilers instead of ailerons for roll control and features an all-flying tail and a trim system. The biplane wing employs a NACA 4412 airfoil.〔〔〔 The aircraft is towed behind a ski tow boat, lifting off at and climbing to about , depending on the length of the tow rope used. The aircraft does not stall, but enters a nose-high mushing condition with a slow rate of descent.〔〔 Plans were sold for US$25 by Corben Development Corporation of Venice, Florida and completed aircraft cost about US$800 in materials in 1983.〔 Skiliar made several modifications to the design, experimenting with landing gear for land use made from automobile leaf springs. He also created a powered version with two McCulloch MC-70 go-cart engines mounted in the aft fuselage behind the wing spar, with the propeller above the engines on a streamlined pylon that housed the drive chains. The powered version was not successful and was returned to glider configuration.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Explorer PG-1 Aqua Glider」の詳細全文を読む スポンサード リンク
