When I ordered my Mavic Air, I spent the time waiting for it to be delivered downloading the manual, reading it cover to cover, reading forums like this one and the DJI forums, watching YouTube video tutorials and "how I lost my drone" videos and downloading the apps to my mobile devices. When it came in, I updated all the firmware and read the manual going through all the apps.
THEN, I took it to the park and flew it very carefully until I was familiar with how it behaves. After 20+ flights now, I have no problem taking it to 400ft AGL and a couple thousand feet away. I have never had it so far I can't see it, nor have I lost connection and had it RTH automatically. I have manually run RTH to see what it would do so I could understand it's behavior.
Now, I have had a toy drone for months with zero stabilization systems that I learned to fly well before getting the DJI. I understand how to control the DJI in ATTI mode because of this prior experience. Haven't had the GPS drop out yet but I did fly it indoors once in ATTI using the downward sensor to maintain position.
I think WAY too many people get a drone, skip the manual and just do the Quick-Start. They ignore all common sense instructions and quickly lose control and sometimes lose the drone, or destroy it. Then, they appear on boards and Amazon's rating system and claim the product is flawed. Manufacturers today have a really tough time. In addition to the actual bugs, assembly flaws and other legitimate issues, they have to deal with a public that blames everything on someone else and never takes responsibility for their own mistakes. While I have seen many legitimate complaints online, I think the vast majority are user errors where the user is trying to avoid responsibility and trashing a product they didn't bother to do their due diligence with prior to use. Don't be those people. Drones are complex devices, subject to wind, temperature and other external forces. While DJI has tried to make it as easy as possible to fly, doing so without a good understanding, and at least reading the manual, will likely lead to disaster. Take your time and go slow and you will not suffer the fate of many an irresponsible drone newbie.
