The Sonerai II, first designed by John Monnet in 1973, is considered one of the most versatile, two-place tandem homebuilt aircraft ever conceived, available as a mid-wing taildragger, a low-wing taildragger, and a low-wing tri-gear.

Fred Keip, builder and owner of the Sonerai II that is parked inside the Affordable Flying Center, completed his plane in 1986 for about $8,500, which he says prorates to about $15,000 today. "I’ve been flying my Sonerai II for 22 years now," Keip said. "The plane has light-sport aircraft characteristics, which is perfect for VFR recreational flying."

Fred’s plans-built Sonerai II is powered by a 2180 CC VW engine and cruises at 135-140 mph while sipping a moderate 4.5 gallons of fuel per hour. "Great Planes Aircraft Supply is a great resource for anyone looking to purchase parts to build their own Sonerai II," Keip said. "Buying each aircraft component separate can save builders a considerable amount of money."
