hello again, I tried my new NGX 600/700 and I don't know why the trim is kinda buggy or it's the way it should work. I thought I have a problem with my yoke since trimming up don't always work, trimming down dose work ?? so is it me or there is something going on ? Thanks.Evan Banalian.

Check to make sure that your joystick is calibrated. The aircraft will not allow you to trim in the opposite direction to elevator input. This is a feature.
