That first flight is always a trip, the whole thing feels like sci-fi filmed on a worn out tape deck. Been at this for about five years now and I still get a kick out of it, but there are some things I'd tell my past self before burning through a pile of motors and props.
Start on a tiny whoop, not a 5 inch freestyle rig. The little ducted ones are forgiving, cheap to crash, and you can fly them in a hallway without putting an eye out. Learn on angle mode before you touch acro. It feels dorky at first but it builds the muscle memory faster than you'd think, and when you do flip to acro your thumbs already know where things are. Also, get two batteries minimum and let them cool between packs. I used to chain flights back to back and cooked a couple of packs that way before someone clued me in. On the analog side, don't chase the cleanest possable signal right away. A bit of static and breakup is part of the charm, honestly. Spend your money on a decent antenna for the goggles before anything else, it makes a bigger difference than most of the gear people obsess over. And set your failsafe before your first real flight, not after your drone lands on a roof three blocks away. Ask me how I know.
The out of body feeling never really goes away either. Six hundred flights in and my brain still does a little double take when the picture lifts off the ground.
