Welcome at LZ design website!

Our main activity is development, production and installation of our "FES" system to a few different types of sailplanes.

FES is innovative propulsion system with foldable propeller, which is driven with strong but very compact brushless electric motor, located in the nose of sailplane. Motor gets power from powerful Litij-ion battery packs. Lighter sailplanes are able to selflaunch with FES. At heavier sailplanes is used to bring sailplane home as sustainer system.
