Technical and artistic genius Leonardo da Vinci experimented with models powered by tensioned elastic materials in the 17th century. Rubber bands have been used by model flying enthusiasts for many years, probably the simplest and most natural power-source to keep flying models in the air for a long time. As long as a strand of rubber is put under tension by turning the propeller, and when the latter is let go, the stored-up power is released slowly and steadily. By using simple, effective rubber-powered motors in flying models, Gunther became the pioneer of a new era of flying toys over 50 years ago. As a result of the excellent aerodynamic flight properties of Gunther models, the power of the twisted rubber band can be used to the full. The flying-models take-off with a flourish, disconnect the free-weeling propeller when the bands has unwound and land elegantly like a glider on the ground. They only need to be "recharged" by hand to take on more power for yet more elegant flights.

For over 50 years Gunther have been developing and producing flying models. To play with these models means to be in contact with nature, to experience the power of wind.
