Hello I need some advice, I upgrade from phamtom V.1.1.1 where I was using a tarot gimbal now with my new phantom vision 2, I'm looking for using a gimbal but I got some questions 1. Can I use a dji phantom vision plus camera on a vision 2 2. What other gimbals can I get but still use the tilt control thru the iOS app. 3. If I use a cheap gimbal thru channel 7 do I'm going to still see the video thru the app?
