I'm glad other people noticed the OP's complaint about an "$1800 hole". I've seen refurbished Air 3 Fly more kits for $1000-$1200.
that made me pretty suspicious, but I'm cynical
it's pretty easy to see which battery is which. I think the Mini 4 Pro combo sends 3 standard batteries. The Plus batteries have to be ordered separately, IIRC
honestly, I don't see what the big deal is about registering with the FAA. It's easy...
OK...it was a misunderstanding on my part...now I do understand...you do not want to debate the policy, which could help you understand it....you just want to complain about it and have them make an exception just for you...right?
