The correct answer is the Platt-LePage’s XR-1 . Platt and LePage designed the XR-1 with a fuselage containing a two-place, tandem cockpit covered with sliding canopies. The pilot flew from the front seat and the observer sat behind him. The empennage consisted of a “T” stabilizer arrangement similar to the one utilized on the Fw 61. A Pratt & Whitney R-985-23 radial engine producing 440 horsepower was mounted behind the cockpit in the center of the fuselage. The rotors were mounted at the end of wing-like pylons that extended laterally and with some dihedral from the center of the fuselage. The cantilever wing pylons were designed to develop some lift in forward flight and reduce the disk loading (aircraft flying weight) bearing on the rotors. Landing gear consisted of two fixed main wheels on oleo struts extending from the rotor pylons and one tail wheel. All wheels could castor freely to ease ground handling. One problem addressed early in the design was downward visibility during vertical landings. The solution adopted then and still used today was to cover the lower nose section in Plexiglas.
