I put a GOPro on my FC40 for the first time today. It really changed the center of gravity. When taking off, it leans forward badly. Once it got airborne, it seemed to be okay. Do I need to adjust to the settings in Assistant to allow for the extra weight of the GoPro? I have a naked case ordered for my camera to lighten the load. I am also making links for the mount to move the camera back to the center of the base. Hopefully, the wider/taller landing gear I have ordered will allow use back there without the landing gear appearing in the frame. I made a wedge and used Velcro to install my stock camera on the battery door.
