I agree, we are working on a solution to this. More on that really soon
Creating a preset is as easy as moving around and clicking the + button. Unsure how easier it could be... Also, you can import Presets from other aircraft in a few clicks. Where's the problem?
Ok, how can we fix that? In the Camera > Controls section you have sliders and text fields. Simply flip the X number to a positive/negative and you have a perfectly mirrored camera.
Not so.. you can set all your presets in the 800 and select the 800 from all the other variants using the dropdown at the top of the Presets list.
Seems to me like you simply don't know how to search for solutions to the issues you were facing.
Search YouTube for some tutorials... you'll be happier in the end.
