ALL MODERN CONVENIENCES: Reminiscent in layout of our own Miles Whitney Straight the American Aeroneer is of full stressed-skin construction and does 147 m.p.h. with a 125 h.p. Menasco C-4 engine. Alternative installations are the Menasco B-4 (95 h.p.), C-4S (150 h.p. at 3,000 ft.) or B-6 (160 h.p. at sea level).
