Excellent ! ... It never hurts to have another quad handy just for parts ... lol ... most people just buy a few extra arms or motors
and stuff, but you'll be ready for just about anything that might go wrong
Start off slowly at first, using "Horizon Mode" (self leveling) and just practice basic maneuvers and puttering around until you're comfortable
with controlling the quad, but do not get too used to the "protection" that mode gives you. As soon as you feel confident in your skill and
ability to fly without losing control you want to switch to "Acro Mode".
THAT's a whole another world because the quad will NOT return to stable flight by it's self ! For example, in horizon mode once you let off the pitch
command input the quad will return to level flight automatically, but in Acro mode it will stay doing whatever you last told it to do until you counteract
that by another pitch command input ... Now you're really flying that quad because it will do anything you tell it to (even really bad stuff like going full
speed into the dirt).
Next you'll want to have a set of goggles (preferably) or at least a screen to see what the quad sees, hence the term FPV (first person view).
After you're comfortable flying LOS (line of sight) in Acro mode, it's time to go into FPV mode (here's where it get really gnarly but really fun).
All of these three stages of learning are an entirely new experience compared to each previous stage.
It's a fun and adrenaline filled experience piloting an FPV racer (especially when zipping through trees) that once you've started you'll be hooked
