DJI refunded my money from the Mavik order in less than 24 hours that's why I didn't have any problems with ordering the P4P from them. But now I'm done with the whole drone thing I think they got to many carts before the horses going on.
Yes ... it's a bit like Ford with all those cars and trucks or Honda with outboards, motorbikes and industrial engines etc, etc.
but as they make the best available and no other manufacturer can come close it doesn't matter.
Not at all like Ford or other car companies when they release a product it's available when it's released sure there might be a recall here or there but the product is usable unlike the P4P and the go app in this case it here is your product but you can't use it because the app isn't ironed out yet. So at this point I have lost all confidence in DJI
RHP, you have to start of first with actually flying your P3P and show us some videos of your perfectly leveled horizon lol , apps and other things can be ironed out through firmware upgrades, however a faulty or failing mechanism can not.
I am telling you, if you do a cold IMU calibration, followed then by a gimbal calibration, your horizon should be straight. This has helped many here correct that glitch. Try it and let us know? ;-)
