Pitcairn XO-61

Pitcairn XO-61
Role Autogyro
National origin United States
Manufacturer Pitcairn Aircraft Inc
Primary user United States Army Air Force

The Pitcairn XO-61 was an American autogyro designed by Pitcairn Aircraft. One of the last autogyros produced, in competition with the Kellett YO-60 and the Sikorsky R-4, it fell victim to cooling problems with its rear-mounted engine[1], and the coming of the helicopter with its ability to hover.[2]

Also known by the company model number PA-44 and the contract designation MX-157[3], the contract for the XO-61 was taken over by G&A Aircraft upon G&A's acquisition of Pitcairn Aircraft.[4]
