You keep talking about the P3 camera, but I'm using a GP hero4 black, so we both agree there is possible comparison, right?
Range wise, I'm not talking out-of-the-box. I'm talking with an Itelite antenna on the Tx, and I get better range than the P3 with it (twice as what I really need.. so no problem 4 me there).
Better gimbal control on the P3? this is news to me, please elaborate. I never had a gimbal problem with my P2V+ and I keep reading about level problems on P3 gimbal.
cost/repair is important to me, and I guess to us all, because we know somthing is always gonna happen sometime.
But the biggest problem on the P3 for me is it still at the testing stage, and all early buyers are the testers. That is why so many problems are appearing with it.
The other big advantage on my rig is, I can upgrade the camera! I dont have to buy a new bird when the camera gets obsolete.
Bu t these are my reasons, I totally understand if you have different reasons and different opinions.
