[1] It employed the same fuselage as the Open Class Cirrus and a similar tail, but had an entirely new wing, high-set and in three segments adding up to a 22 m (72 ft) span.
[1] The Nimbus had a rudder far too small for an aircraft of its size, leading to very unfavourable control characteristics; After the pilot applied full aileron and rudder inputs, the glider continued to fly straight ahead for several seconds before suddenly dropping a wing, requiring full opposite controls to recover.
[1] George Moffat of the USA flew the Nimbus in the 1970 World Gliding Championships at Marfa, Texas.
He had to modify the aircraft's cockpit to fit in, and became the first person to sample its spin characteristics when, in mid-competition, the glider departed from a steep turn into autorotation with asymmetric water ballast.
While considering bailing out, he remembered that the spin of the similar Akaflieg Darmstadt D36 could be tamed by rocking the stick back and forth violently.
