Update:
After messing with the Mavic, he heard something fall out. He later found that it was a screw. IMG_0819 — Postimage.org
Things like this is the reason why I'm always a bit hesitant to "jump-the-gun" and pre-order. Crossing my fingers, hoping my Mavic arrives and performs without a hitch.
Looks like I'll be double checking screw tightness. Probably a good idea after several flights anyway. I'm used to it with my helis as I've had a mishap or two from loose screws.
