This is not a game, it's a sim meant to train you to fly FPV quadcopters. If you aren't interested in flying real life quadcopters and you don't have an actual transmitter to play it with then IMO don't even bother. I recommend the Radiomaster TX16S, great transmitter for the price and it works perfectly in this and every other sim I've tried it with:
I dont know, ive never flown a drone before but I picked it up in about an hour, only thing that really gave me trouble was the rolling. can you program real drones to not roll past a certain point? because thats what usually causes my crashes, flipping sideways 20 times from just a little touch
