I like it but if I cannot see the I-pad in the daylight it is not worth much to me. My Phantom 1 with FPV is fine and it is like an antique to the P3P. My TBS Pro is great to fly but it has different if not more issues the the DJI product line. I understand it's not perfect but If I cannot see the app I need to find a way to fix that or it is no use to me.
Would it be reasonable to try using whatever device that you CAN see with on the P# rather than your Ipad.
If you can use fpv on the p1 just install the p3 app on the I-device or android that is daylight visible with p1. I don't have a p3 so I don't know if that will work but .....
