Used bag of rice with a wet cell phone the other days. Back to normal in few hours. Rice was around. Not enough little bags of silica gel.

Try putting it in a sealed jar with dry silica gel (blue).

If there is condensation this should dry it out.

Try taking it home and putting it in the airing cupboard for a few days.

Doesn't always work but worth a try.

I guess it will need a trip to Winter this winter (no joke intended).



Out of curiosity, does anyone know what causes this sticking and has

anyone successfully fixed this problem in the past.



We had the same symptoms in our 57mm Winter mechanical vario, after the

glider had been out of service for maintenance for a month or two. We

ignored it for a while and after 4 or 5 flights the problem went away.

That was a few years ago and the problem has not recurred.



I can only think that there was some condensation in our instrument

during the lay up and that some "internal ventilation" and/or solar

heating on the front panel dried it out again.



So maybe try and fix it by flying it!
