Is there a way to adjust the top speed of the Phantom 3 down? Could be useful in making aerial videos where you don't have to go real fast. Trying to do shots where you move forward and up at the same time towards a subject while tilting the camera down so the subject stays stationary in the frame. I know how to adjust the gimball speed which is useful, but kind of hard to maintain a slow constant speed forward and up at the same time while tilting the camera down. Ideas?
