Cyclic sticking when using trimmer

[McGraw]

Recently I've tried using my gunfighter sprung so I don't have to keep messing about with it moving from fixed to rotary.

I've sussed the trimmer except sometimes it just sticks in place and the cyclic won't move forwards despite being trimmed at half way.

Rocking it back and forwards releases it but I get violent movement afterwards obviously.

Why is it sticking in place?

Thanks

Have u set the trim as center trim in the special tab? Than u have to center after every trim release.

if u don’t like it, choose instant trim in the special tab
