Warning about using photo bags. Lenses and SLR bodies are usually very sturdy; in case of a fall, all they need for protection is some soft padding like those soft dividers. In case of Mavic, if the bag falls and the inertia concentrates on gimbal dome, it can be pushed in/disloged and can damage the gimbal (speaking from experience; Mavic was in its Fly More bag; fell a mere 1ft; the dome was pushed in from the front almost 1cm; pure luck that it didn't smash the gimbal). Precise-cut foam can better diffuse the inertial forces than those dividers.
Just a hypothesis based on one data point and some thinking. YMMV
