Boy when you jump in, you go all in don't ya? The
M2P is certainly no beginner drone. I am not saying with due diligence and time you can't learn on it and with that kind of overhead, the sky is your limit on learning. But I really think at this point in the game you learn flight characteristics and develop a skill set with a much cheaper drone that will give you a basic, then intermediate to advanced skill of flying and filming with such a rig.
As far as where to go to learn, you would do that on your own, possibly locally at a flying club, like the rest of us did (Hopefully) with tips and tricks and this place is fine for that...and YouTube is your friend. If I had to make a call I would say get you a good clean used MP1 fly it for a year, save the thousand. Come back out next year when the
Mavic 3 has matured and jump on that wagon for a few years. All IMHO
