Construction plan Snark

Jochen Zimmermann became aware of the Snark model by chance when he saw a remote-controlled replica flying on a slope. He was spontaneously impressed by the unusual shape and so the decision was made to redevelop the model in a slightly larger size and to give it a special extra. The aim of the design was to increase performance through modern profiling and to implant a drive into the model while maintaining the striking appearance. After extensive considerations and preliminary tests, an EDF that folds out to the side has proven to be suitable for everyday use. This turns the glider into a motor glider, the drive of which disappears completely into the hull once the work is done and can fold out again if the thermals subside.

The enclosed construction plan was published in FMT 02+03/2024.

The construction plan print is supplied by the publisher (in contrast to the supplement construction plan) printed on one side and undivided in 1:1 on white paper. The delivery includes the building description.
