I bought and installed a Fix 2, one with doublewide tape. After a shop visit, I had the chance to add the next generation design that screws on with three tiny screws. It seems so easy to bounce the gimbal, tear the flat cable or misalign the horizon...that this $20 Fix2 bracket seems like a no brainer. ($20 to save $700).
Other advice I gained from watching many hours of video...fly low in an open field doing simple skill sets. Fly and Fly some more. Don't do anything beyond "driver training" until you have 10 flights under your belt. Take off slowly, loiter, fly in squares, land, repeat.
Put prop guards on your bird...a clumsy landing can cost you a set of props. It would be easy to bump into a tree and break props. It would be easy to bump into a dog/bird/person and do a nasty weed whack. You would be liable for such injury. Put on prop guards.
I installed a set that screw on. Made it clumsy to keep my bird in its box, so then bought a set of quick-removing prop guards. I now have a spare set of guards.
