Just got the Phantom3 Profeesional.
While unpacking I noticed the usual... gimbal clamp was off. I see this was due to the foam block preventing it from entering the little guide in the gimbal.
After removing the foam, it fits fine.
The camera though is hanging straight down and seems there is no resistance in the pivot.
( It moves freely) Is it normal to hang down with the gimbal clamp off?
Hey thanks for the help. I'm newbie and being cautious.

It hangs loosely until you power it up and it snaps into place.

Awesome, thanks for the quick response.
