Aw c'mon.... Some people have trouble with manuals. They can be dyslexic, or learn better through observation of demonstration. I'm a technical guy and even I have had some trouble understanding parts DJI's manual. Quite often engineers write the manuals, and they make assumptions about what the user knows. It's what we in the engineering discipline call the "Well, Everyone Knows That" syndrome. Best thing to do is to tell someone who asks, where alternative sources are. I tell ya, I've learned far more about my Mavic, and how to use it best, watching YouTube.I refuse to help someone that won't read the manual
