Now with the AS33, the trend towards higher wing loading continues.

If you have 18m and open class in one competition (which is often the case), tow planes should be capable of towing 60kg/m² gliders at a safe speed with decent climb rates. They should also allow for 850kg MTOW on the rope for the Nimbus 4T waiting in the grid. There are not so many tugs available with this combination.

What would you consider to be a safe aerotow speed with a 21m-JS1c when fully ballasted?

Fully ballasted 70 knots minimum at all times (especially low down) what the manual specified. NB I interpreted that as being on the glider ASI as some tug types ASIs over-read significantly in the air. Pawnees seem to over-read by 5-7 knots probably due to not having accurate static pressure inputs so I asked for 75 knots with them. I always kept radio contact with the tug pilot.

My own club only had a 100 hp Eurofox so I never aerotowed the 21m there at more than 550kg and it wafted along happily at 65 knots.

For race, you would want exatcly "low energy glider", competitions are not flown at vne & FL180. I wouldn't call V3 that, but if it will come out as good climbing glider it is a winner. Historically, almost all really succesful gliders are best climbers in it's class ( Discus, V2, LS8 etc.) Haven't had chance to compare my ASG29 to V3 yet but i do think that JS3's are not better (with 15m tips). With 18m wings it might be different story.

You are wrong concerning the 28 : it never made results in the standard class. It never broke the LS8 and discus2A domination. A good glider but not a beater.
The 30 was a failure in competition : too heavy, exceeding weight limit. Definitely not Ã* beater.
The 31 is a good cross country glider but not a beater in competition.
The ASG29 was and still is a beater in competition !

Schleicher and Schempp have a long history of making great gliders. Jonkers has started that tradition too, however they have only produced a handful of gliders compared to the other two listed.


The Jonkers started out with the aim of building a world class 18m ship.
In the upcoming world championships 17 out of 46 in the 18m class are
Jonkers so I guess they have achieved that.

I would have thought that competing with a 21m glider against 28m
gliders would be like taking a knife to gun fight. But 17 out of 32
entries in open class are JS1c's. That's over 50% of the entries! They
have changed the nature of open class.

Then there are 5 out of 37 JS3's in the just started 15m championship.
They were placed 1st, 4th, 5th, 6th and 12th yesterday.

Of course there are no Jonkers gliders in the club class! Most of the
club class fleet were built when the Jonker brothers were still at school.

What is surprising about their achievement, is not that they have
designed and built world competitive gliders, not that they are
competitive in 3 different classes. But the speed with which they have
managed to progress from drawing board (computer) to prototype to
production and certification.
I bought my JS1C with 18 and 21m spans. I've owned an ASW27B, ASG29, and this JS. The JS is the best fit and finish- hands down. 7 hours on the engine and all for fun! I've flown it 200 hours now and wings are beautiful. Both my 27 and 29 developed spar bumps. One glitch on delivery and that was the FLARM was set up for Europe. Won't go into the issues that I had with the 29, but they weren't bad enough that they swore me off AS. I just ordered an ASG32Mi as a second ship, but if JS had a two-place 20m, well, the decision might have been tougher!
