ANDY DAVIS


The prototype 18 metre JS1 Revelation is a fabulous looking sailplane, beautifully finished, with impressive build quality and I was lucky to have the opportunity to fly it during a recent visit to the Potchefstroom factory. The cockpit is comfortable, well laid out and I felt immediately at home as I settled into it.

Flying fully ballasted and close to 600 kg AUW, I was impressed by the harmonisation of the controls, easy handling and docile low speed behaviour.

The stall was gentle with a slight and easily controllable wing drop, recovering immediately on release of control stick back-pressure.

After an hour of local flying exercises, I was joined by Uys Jonker flying an 18 metre Ventus 2CT , also heavily ballasted, and this gave me a chance to assess the relative performance of the JS1 during our subsequent 500 km cross country together.

 

The JS1 soon showed its impressive potential, consistently pulling away from the Ventus as we carried out long glides throughout the speed range in good soaring conditions.

Landing was straightforward with a low approach speed, the triple paddle airbrakes providing easy approach control and no noticeable tendency to drop a wing on the landing roll.

There is still some detail design work and aerodynamic fettling to attend to, but basically the design team have got all the essentials right at the first attempt. That their first ever prototype should fly and perform so well is a stunning achievement. Uys and Attie should be very pleased with themselves.
