The LAK-17C Fes
Simple and safe. Does not matter where you fly, the new LAK-17C FES will get you airborne or get you home.
Designed for the new FAI 15 m and 18 m classes.
Safety
50 years of sailplane design experience. Modern composite materials, tested manufacturing techniques and, just in case,
an option for an engine. The FES propulsion system has no known reports of in-flight failures,
allowing you to stay confident in areas of no-lift. And yes, it is still a glider.
Comfort
No sweat from rigging to landing. All controls hook up automatically. We offer to choose one of 4 of our
standard instrument panels. It is possible to get a self-designed instrument panel as well. Pedals and seat-back are
adjustable.
Performance
This highly-maneuverable glider fits 160 liters of ballast in the wings and 8 liters of ballast in the tail. The FES engine and batteries
are easy to remove in case a pilot wants to fly pure glider in competition. In this case possible to have extra ballast the fuselage. With the propeller removed, a clean and sleek nose cone is mounted on the front.
