Well, now you know that its possible to spin it without the kit: my club
has never had a tail-weight kit and doesn't now despite owning two
ASK-21s.
We still have our Puchacz and for spin training or a spin refresher. That
is what I'd expect to do annual spin checks in. I'm looking forward to
doing just that as soon as we can fly again.
I didn't say spinning an ASK-21 without weights is easy, just that it can
be done if both pilots are medium to light weight.
I had a trial flight at Blue Ridge Soaring (16 Oct 1999). The CFIG was
large, I'm not. Anyhow, he attempted to demonstrate a spin in their
ASK-21, the first glass glider I'd even seen, and could not get it to
spin, *but* (1) he was heavy and (2) he tried to provoke a spin while
flying quite a bit faster than stall speed. All his attempts seemed to
start to spin, but became the beginning of a spiral dive after around
half a turn and were promptly rolled level and recovered.
But read the Edwards report to get a professional opinion about it. Their
view is that an ASK-21 will spin (upright AND inverted) and stall but
that the POH was inadequate and incorrect. Presumably the POH has been
amended for the ASK-21B.

Wrong. I said its nicer to fly solo than an ASK-21, not that it is
forgiving. You certainly won't find me flying one slowly below 1000 ft.
Please don't misquote me again.

I don't know whether the 10% figure is right, but I am well aware that
quite a lot of them have been crashed.
