I've got one as well and I'm pretty sure that's the reason it's placarded
against ground launch.

I had mine freeze shut also. It was raining lightly before we took off

I then went to over 20K in our wave. I was at altitude for quite a long

and discovered while descending that the spoilers on my Jantar 2A were
completely frozen shut. I tried everything I could to get them open
without
success. In the manual it states that the 2A is not approved for
slipping.
Our runway is 3000ft long at 600ft msl. Fortunately we usually have
quite
a bit of wind here so that helps shorten the landing. I modified my
pattern
and had no problems getting it stopped well before the end of the
pavement
with the wheel brake.

Well done! I've a Jantar 2a and pulling this trick off at Aboyne
would be ... interesting. One time when the separate wheel brake is a
good idea.

If anyone is wondering why the Jantar 2A is not approved for slipping,
what seems to happen is that the elevator looses effectiveness -
presumably because it is blanked by the rudder. You start to feed in
aileron and opposite rudder, then find that you have the stick on the
front or back stop to try to control the attitude. Not something to
discover on the approach:-)
