I do but its just normal flying around lol nothing fancy.
Plus my lil cousin brother was learning how to fly so was teaching him while it was being recorded.
I have had the app crash on me many many times on my note 4 and I can assure you I have never lost control of my P3.
With my ipad
mini 2 I have never had the app crash.
Also since you do not have a cell version ipad mini you wont be able to set a new home point if you were to move with your controller from the take off point as non cell versions have no gps.
Also RTH function works a charm and has so far never let me down, just make sure you set a reasonable height for if it were to be ever used or get automatically activated.
I have had situations were I'm a kilometer out and have had the app crash, all I did was press and hold the RTH button and it has always come back.
But if its LOS flying then you will have control wether you have FPV or not.
You will enjoy your P3 just make sure you fly safe and do all the relevent checks before take off.
