This is one of the easiest to fly competition grade gliders I have ever flown. Even full of water at maximum allowable weight of 600 kg total weight she is easy controlled. Very pleasant to fly, comfortable and efficient in thermalling, easy to center. And she shines at high speeds!
Max Glide Ratio (L/D) of 53 gives you a lot of options when choosing your flight strategy.

Tuned for competitions
Wings repainted and optimized at Jonker factory in November 2013 (due to typical printout of spars after one year after manufacturing it is beneficial to check and correct wings surfaces exactly to the original wing profile; the difference is subtle, but in order to optimize the glider performance it is advisable to do that if the glider fly in competitions; once corrected the problem do not reoccurs).
Glider has never crashed, never needed repair beyond normal usage and maintenance. Full maintenance history available at service center.

The glider was flying in Europe from the beginning. First in the Netherlands, then in Poland. Jonker has agreed with the South African Aviation Authorities to extend the airworthiness certificate in Europe at selected maintenance centers. There are few of them in Europe. I am not sure how it is organized in other parts of the World. It was first maintained in the Netherlands, and since I am its owner, in Poland. I've never had a problem with prolonging CoA for the next year. The same with the insurance.
The glider is in Międzybrodzie Żywieckie near near Żar Mountain and Bielsko Biała in South Poland.
My dear friend, Sebastian Kawa, with whom we were e.g. flying together in Himalayas, was using my gliders from time to time (e.g. Previdza 2016, and many individual explorations). Here is one of his winter flights:
