After enjoying success with his original VW-powered Sonerai, John Monnett decided to develop the Sonerai II, a tandem-seated version. Both pilot and passenger sit under a bubble canopy that is hinged on the right side. The Sonerai II differs mainly by being slightly larger, making use of a somewhat more powerful engine, and by being stressed for aerobatics when flown by the pilot alone. The Sonerai II is now manufactured by Great Plains Aircraft, Inc.
