The JS4 Rengeti. 15/18m Standard Class Sailplane
Piston Glider Jonker Sailplanes
Description
The JS4 Rengeti , the most modern standard class glider, available from 2025.
Pilots can select the JS4 as a pure glider, or have a choice of propulsion systems :
-The MD-TJ 42 jet sustainer system , or
-The Solo electric sustainer/self-launch system
Standard options on the JS4 have been carefully selected, making the JS4 the best value-for-money new glider on the market – designed for all pilots… making world champions…
Optional 18m outboard wingtips transform the JS4 into a real performer, adding that extra bit performance to compete in other classes.
UNMATCHED
PERFORMANCE
The JS4 Rengeti is designed to set the new performance standard with an
optimised low drag fuselage, a high wing configuration for improved climb
performance, and new wing airfoils with a 5th generation winglet design.
The JS4 has a fuselage similar to the JS3 with extremely low drag properties over a
large range of velocities and angles-of-attack. It’s a small fuselage designed with
high-tech software to provide comfort even to our well-built customers
