Wilbur Staib (1914-1993) was a self-taught aircraft designer from Diamond, Missouri.
Staib served as a flight instructor during the Second World War at Chanute, Kansas flying PT-14's.
Staib designed and built five different "LB" (Little Bastard) aircraft and a helicopter, of which several had the title "world's smallest" at their time of construction.
Staib flew his aircraft in airshows with the title "The Diamond Wizard".
The gearbox is sourced from a Ford Model A, the clutch from a Studebaker, the rotors cut down from a Brantly B-2 and cooling system from a Chevrolet Corvair.
