This is one of the coolest app I've used. It may be limited to a number of people as it uses a controller to control the drone but it is one of the more flexible way to do cinematics. I've test it for an hour and there isn't any hiccups.
The upsides is that, you have a large amount of adjustability like the speed of the camera movement, deadzone (which are very useful for me since my stick doesn't go back to centre after releasing it), and even how smooth you want the camera to tilt or move around. There is a "Follow Car" function, it's make easier to concentrate on how your shots look than focusing on chasing cars down is a good thing. Another is that the ability to capture shots at any angle. Using Camtool 2 for a good amount and switching to this, it just makes certain things much easier without having that heading glitch where it does a weird 360.
The downside is that the "Follow Car" function makes the camera fairly difficult to move into how you want it to look, but I may change that statement as I've only used for a fair while. Another downside is that you are only able to move in a certain area like in a square box but it is suppose to be the improvement on Box Cam.
Some suggestions on changes or additions to improve this mod is to be able to switch between cars on the fly, but I've never made a mod and it may be impossible. Another is the button logo of the "Drone Camera" and the "DOF Mode" should have both Xbox 360 and Xbox One Controller logos since as a new user, I gotten somewhat puzzled how to activate the drone as none of the buttons were on my controller (Using Xbox 360 controller btw).
To summarise, this is an amazing mod that will help more players to create more interesting content for the future.
