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.

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.
