I recently noticed while flying my Mavic Mini that its front right arm vibrates loudly while descending. Especially when I start to descend, the arm visibly vibrates and makes a low-pitched sound as opposed to the normal high-pitched buzzing. Is this an issue?
I checked the screws holding the props on - they're tight enough, and the props are only slightly chipped (much of the silver stripes on the end is still there), and that goes for all of the props, not just this one.
Could someone tell me what's going on / how to fix this? I'm concerned the drone will fall out of the sky if something breaks loose.
