Warning:
When FES is installed on an 18m class sailplane like Ventus 2cxa
or Discus 2c, it functions as a sustainer system only. Taking off using the
FES is prohibited unless explicitly stated in the flight manual.
On lighter UL sailplanes like Silent 2 Electro or MiniLAK FES, the system
functions as a self-launch system.
