The L-164 was developed from the Bushcaddy L-162 as a true four-seat aircraft. Unlike the L-160's designation, which indicates that the design engine for that model was originally a Lycoming O-320 of 160 hp (119 kW), the L-164 designation is just a numerical sequence and does not indicate horsepower.[1][2][6]
The aircraft fuselage is made with a frame of welded 6061-T6 aluminum square tubing, covered in 6061-T6 sheet. Its 36 ft (11.0 m) span wing employs V-struts with jury struts. The wing has an area of 189 sq ft (17.6 m2) and flaps. It can accept four-stroke powerplants from 180 to 250 hp (134 to 186 kW), with the Lycoming O-360 of 180 hp (134 kW) and a Franklin Engine Company powerplant of 220 hp (164 kW) commonly used. Cabin access is via two fold-up doors.[1][2][3][4][5]
Construction time for the factory kit is estimated at 1200 hours or 300 hours from the quick-build kit. Four examples had been completed and flown by December 2011.[1][3][4]
