Spinks Akromaster

"Pappy" Spinks provided the funding and name to Charlie Hillard for the creation of the Akromaster.^[2]

The Akromaster is a single-seat, low-wing, monoplane with conventional landing gear and a symmetrical airfoil. It features inverted fuel and oil systems and an air show smoke system.^[3][4]

During certification testing of the cabin version of the Akromaster, aerobatic pilot Harold Krier was unable to recover from a flat spin and died due to a parachute malfunction.^[2]

Charlie Hillard flew the Akromaster prior to forming the Red Devils aerobatic team. Hillard placed third in the 1970 world aerobatic championships with the aircraft.^[5]
