Pilots can select the JS3 as a pure sailplane, or have a choice of propulsion
systems:
-The MD-TJ 42 jet sustainer system , or
-The Solo electric sustainer/self-launch system
Optional 15m outboard wingtips transform the JS3 into a fast, agile 15m
glider, the preferred option in the 15m class.
Standard features differentiate the JS3 in its class – designed for pilots with
an appetite for the ultimate performance.
Proven the best in performance, safety, handling and comfort.
UNMATCHED PERFORMANCE
The JS3 sets the bar in the 18m class. It will be a dominating force for many years to come.
In the 15m configuration, the JS3 has proven itself to be equal or better than any competitor.
The 60 kg/m 2 wing loading combined with a high performance fuselage gives the JS3 its high speed dominance.
The high-wing design was perfected for maximum drag reduction and an increase of effective wing area – enhancing slow speed flying and climbing.
