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.

No sweat from rigging to landing. All controls hook up automatically. We off er to choose one of 4 our standard instrument panels. It is possible to get a self-designed instrument panel as well. Pedals and seat-back are adjustable.
