I was wondering if there as a way to upgrade the Stock FC40 camera yet still use the same FC40 holder?

Basically is there another camera that would fit in the FC40 camera holder?
Thanks!

The stock camera being relatively low is one thing, but the app on iOS is terribly unstable. It constantly crashes and I can't reconnect unless I power everything down. Wouldn't mind but my Phantom doesn't get further than about 25-35 metres and it drops out!
