Not sure what Wags was meaning with View.lua because there are individual files per AC and there was nothing at the line he pointed out.
If you want better control of speeds look into the .\DCS World\Config\Input\CameraObject\keyboard\default.lua. Here there are additional camera controls which will not show up in the keyboard mapping screen. You can change the speed of movement (page up, page down) and the rotation speeds of the camera (comma and period).
