The Sky-Walker is an open microlight aircraft constructed out of pipes and cloth.
This was a real challenge. The ribs of the wings needed to be formed as a spline curve, meaning a constant changing radius. Also the horizontal and vertical stabilizer were made out of bent parts.
The hardest part was the manufacturing of the ribs of the wings. Because of the constant changing radius, a separate program had to be made. Despite the very tight radiuses we were able to deliver the desired parts. Thin walled aluminum was used for keeping the weight low.
Summer 2010 the first test flights were made.
