right wing keeps dipping down

Yes, you do need to maintain trim during flight as flight conditions change if you want your aircraft 'hands free' (i.e. so that you don't have to apply constant input pressures).

Trim wheels are much better than button clicks for fine trimming. I use a G940 and in the axes tab of the controls config was able to assign three trim wheels from the main stick to the three trim axes. Unless there is a specific issue with CH support, I would assume the method is the same and just double click the trim you want to assign on the right and then move the corresponding trim wheel on the stick. I did have to recalibrate the wheels first.

Likewise, out of the box, I had weird pedal assignment and just had to ensure that each control axes was assigned correctly in the same way. Somehow I had a throttle wheel assigned to rudder.
