You need to revisit your setup. The V2 is a lot different than the v1.2. I use the 3gx and it is flawless as long as you have centered your head and links and no trims. FBL does not like trim and thinks it is a control input. Some sub trims on the 3gx at set up is ok because you are setting up the head with it in mind.

When starting your set up set your pitch curve to 0-25-50-75-100 and your swash mix to achieve the pitch in collective say 11-12 degrees for a .50 size and 8degrees in cyclic.
