When I put my nexus 10 on my inspire controller and add the sun hood the whole setup shakes around a lot...
I have tried tighting everything up but still seems loose. I have checked other sites and they replace the plastic bracket
with a metal one, but the inspire all ready has a metal bracket.

The only way top do it is to tighten the bracket.  There might be some other 3rd party holders online you can check

Chris, would you mind commenting on your experience with the Nexus 10?  I'm getting a Phantom 3 Standard and have no idea how well the Nexus 10 might work with it.  As you know, it does not have a cellular network connection. Thanks for any information.
