In North America the Cuby II was sold for US$15,662.76, complete with propeller, 50 hp (37 kW) Rotax 503 powerplant, paint and fabric in 1988.

I'm pleased to mention that the delightfully balanced rudder was smooth and linear in response—the best I've felt in an ultralight or homebuilt.
Touch and goes in the Cuby were so much fun that several abbreviated pattern circuits ensued, with a half dozen landings accomplished in ten minutes.
