The Hillson Pennine was a 1930s United Kingdom two-seat cabin monoplane designed by Norman Sykes and built by F Hills & Sons of Trafford Park.
[1] The Pennine was a small high-wing braced monoplane powered by a 36 hp (27 kW) Praga B two-cylinder piston engine,[2] though originally designed for an 80 hp (60 kW) Aspin engine.
[2] The Pennine, designed to be simple, had an unconventional control system with a normal elevator and spoilers on the leading edge of the mainplane, but had a fixed rudder with just a trim tab and no ailerons.
[4] The Penine became airborne during a high-speed taxi test on 4 February 1937, the controls had not been adjusted and it took Sykes half-an-hour of circling to the left to get down safely.
[4] The aircraft was not flown again, the company concentrating on a design for a trainer (the Hillson Helvellyn) and with space a premium for wartime work the Pennine was dismantled.
