Design and development

The Grasshopper is intended to be a simple single surface glider with easy handling and modest performance for flight training and school use. It employs a very large wing area, low aspect ratio and low weight to make it easy for students to take-off and land. Unlike many hang glider models, the Grasshopper is available in just one size.[1][2]

The aircraft is made from aluminum tubing, with the wing covered in Dacron sailcloth. Its 10.2 m (33.5 ft) span wing is cable braced from a single kingpost. The nose angle is 120°, wing area is 21 m2 (230 sq ft) and the aspect ratio is 4.95:1. The take-off weight range is 68 to 110 kg (150 to 243 lb) and pilot hook-in weight range is 45 to 85 kg (99 to 187 lb). It is certified as DHV Class 1.[1][2]
