I am not satisfied with the Joystick missions as these rely on continuous Excellent Quality connections between the transmitter and drone for smooth footage.
I have a P3 S with a broken gimbal which I tried unsuccessfully to fix with non-DJI Chinese parts from Ebay.
Just for fun, but I think is getting more serious, I set up a P3 Standard to carry a Mini and I am very happy with the results. The setup is about 1320 grams which is not a problem, I flew over 1000 km with a dual battery heavily modified P3 Standard which was about 1350 grams and there were no problems at all caused by the extra weight.
My first tests are very promising. There are no vibration-induced movements in the video and the “rig” flies well. There definitely is reduced aerodynamicity but I have flown it as hard as I could it in ATTI mode, full-throttle spins, up and down and so on, and it just goes nicely and reaches over 50 km/h. Mission mode is no problem as well, Including when there is no signal from the remote, I just turned it off and the mission continued as expected.
Here are some videos for those who are interested:
