The Laister LP-15 Nugget is an American single-seat, high-wing glider designed by Jack and Bill Laister for the FAI Standard Class.[1][2]

Design and development

Designed in the 1970s, the Nugget was intended to compete with the new European fiberglass gliders that were beginning to appear, and as such incorporated mixed construction methods. The fuselage is built with a fiberglass cockpit area, with the fuselage aft of the wing trailing edge made from aluminum. The wing is of Chem-weld bonded aluminum construction, the bonding replacing rivets in an attempt to get a surface as smooth and wave-free as fiberglass. The wing employs a Wortmann FX 67 170/150 airfoil and has flaps. The long span flaps serve both as speed-range drag reducing camber changing devices and full deflection high-lift/high-drag landing flaps. The aircraft can carry up to 185 lb (84 kg) of water ballast in a center fuselage tank, located at the center of gravity. The landing gear is a retractible monowheel.[1][2]

Even though several sources report that the LP-15 was type certified, no type certificate was ever filed for it and all aircraft are registered as Experimental-Racing, Experimental-Exhibition or Experimental-Amateur-built. The LP in the designation indicates Laister Products and the model number is the wingspan in metres.[1][2][3][4]

Operational history

As of January 2016 there were still 9 LP-15 Nuggets registered in the USA.[3]
