Something wrong with your current Phantom 3 kit setup, or a crash perhaps?
Why do you want to switch out your factory installed unit?

3 party cameras are not suppose to be working on phantom 3... Also I believe that Go Pro camera with it's fish eye is not better then the flat lens of  P3

Looks like it might be a good gimbal.
If it comes even close to the performance we're used to from the Zenmuse at a considerably lower I might afford one for my P2.
Somehow I think the Zenmuse is still king of the hill though.
Need to get airbourne again before I loose whats left of my sanity
