A final view of the PA-39’s recent run-up. The rotor is unpowered in flight - it simply windmills - but a clutch system connected to the engine allows it to be run up to take-off speed while the aircraft is stationary on the ground.

The Pitcairn’s tail surfaces. The outward-canted tip fins utilise the rotor downwash to help counteract the propeller torque.

The PA-39’s rotor head. Steve Pitcairn replaced the original rotor blades, which were destroyed in a landing accident in 1960, with units from a Piasecki HRP-1 helicopter. A set of 6 3/4 in-long extensions were specially manufactured to adapt the new blade-roots to the old hub.
