Watch all the you tube vids on the M2 you can. (This does include reading the manual a couple of times.) Don't expect to remeber it all, just be exposed to it, and if it does come up with an issue, you will more than likely know where to look for the answer. Failing that, you come here.....
Now, as to the comment "Is it fast?", well, kinda, fast enough. Remember, it is a camera ship, not an FPV racer. If you treat it like a camera ship, you will have many hours of enjoyment, and nice vids/images. If you treat it like an FPV racer, you'll be back here alot.....
Enjoy, welcome, and take your time......
