RC light-wind glider (PoD)

Flying from upwind to upwind without propulsion and fighting for every metre of height – that is the fascination of pure gliding. If you want to enjoy this without the electric drive that is so common today, you should pay attention to a few things when building your models. The author, Dr. Heinrich Eder, is a specialist in the aerodynamic peculiarities of light-wind gliders, and in this book, he makes his research results and experience available to everyone.

Where do you place the turbulator, how do you calculate the setting angle difference, how do you optimally design winglets or find the best wing geometry? This technical book answers such questions and imparts the knowledge needed to design and optimise one's own constructions, with many photos, diagrams, and drawings. In addition, there is tried and tested advice for stable lightweight construction and successful flight, as well as many examples of proven light-wind gliders.
