I had that same thought.
When I first started flying the Mini-2, I underestimated how
vastly different "reverse flying" is, in terms of your natural eye-finger coordination. In "reverse flying", your strong natural inclination is to do the wrong thing. I had one crash (non-fatal to the drone), and a bunch of close calls that resulted from this early on.
It does get better. I still have to flip the mental switch when I'm flying in reverse mode, but once I've done that, it works.
I have three suggestions for skill development, all of which I employed for myself to good advantage:
1) Fly a lot. Then fly some more. Then...
2) Buy a Snaptain H823H micro drone to practice. They're cheap, 23 bucks on Amazon the last time I bought one as a gift a few weeks ago. You can practice reverse flying (and sideways flying, and...)
indoors to build both your skill and confidence. The H823H is nearly indestructible and non-destructive. You can bang it into stuff indoors all day long, and you damage neither it nor what you bang it into. Besides, this would give you something to fly until your Mini gets back from the Drone Hospital... ;-)
3) Pilot Institute has a course on basic maneuvers. Take it! They also have a "Deep Dive" course for the Mini-2, which is free, and worth every minute of the time you spend watching it.
Hope this helps!
