I add Axiom II antennas to my goggles, hand stabilizers to the drone and a protective cap with battery chassis. None of them fit the current cutouts, and you'll have to take a razor blade and trim them to fit you as best as possible. No manufacturer error, since the case fits very tightly on all common items, the goggle fits very tightly, so there are problems when removing or attaching the Google glasses. I only wish it would make a version or make it easier for you to install these popular updates. There is also no space for a charger when you buy the Fly More Combo.
