Garug, thank you for responding. We are using a BirdyCam 2 gimbal with a Hitec Minima 6E receiver controlled by a Hitec Flash 7 transmitter.
Our left stick is controlling pitch and roll and the stick goes back to center once you let it go. I can roll the camera left and right without it going back to level, but if I pitch it down or up, it goes back to level. The right stick is controlling yaw by moving left and right, and it will also go back to level.
I do have "Follow" disabled in the SimpleBgc settings.
