I have to ask since reading all of the issues kind of freaks me out. When I first take my Mavic out and take off if I let go of the stick during a climb there is a moment where the drone acts like it dropping and then recovering. Is this a normal behavior? It only seems to do this in the beginning while it's still cold. Once it warms up it seems much more like I'd expect it. I just want to make sure I didn't get a copter that is going to drop from the sky some day soon.
