Tested yesterday with Advanced Flight model and it's so cool. I liked very much... but i think it should be a little more difficult to fly the heli with Cargo...
Usability - It will give an awesome new experience to the game if we will be able to cargo boxes of ammo and other stuff...
Difficulty - It's easy, maybe i'm used to the difficult of DCS flight models...
Multiplayer - Didn't try
Maybe with AFM finished will be more difficult, as it has to be... We will see... At the moment, keep working guys, your job it's awesome :).
