K21 trim tightening?

[[email protected]]

The trim in our club's K21 is no longer effective and I suspect it is probably a simple matter to tighten up a nut somewhere below the front seat so there is more friction on the trim lever.

If anyone had a moment to confirm my suspicion and had any pointers, that would be appreciated.

The bolt on which the trim lever pivots is fitted with a knurled nut for
exactly the purpose you require!

Thanks! Is it accessible through the stick boot or does the seat pan have to come out?

It should be accessible without removing the seat. If you have the
original Schleicher cushion the boot is part of the cushion. It is held
by pop fasteners at the front edge.

There's also some usefull information in the flight manual on trim
adjustment. Is worth replacing the springs as well under the rear floor
pan. They tend to loose their pull after so many years of use. Very little
cost.
