The Long Henderson Longster HL-1 is an American aircraft that was designed by Leslie Long and Ivan Diggs for homebuilt construction.

The Henderson Longster is a conventional landing gear equipped, wire braced parasol wing aircraft. Aeronautical designer Ivan Diggs designed a new 30 ft wing for the Longster.^[1] The wire bracing is supported by a central cabane post located over a 1 U.S. gallon (3.8 L; 0.83 imp gal) above-wing fuel tank. The fuselage is steel tubing. The design also features pinned and brazed gusset joints as opposed to conventionally welded joint clusters.^[2]
