Please allow me to step in.
Learn to fly? I'm sorry but what are you talking about? That would not be a legitimate efford put into control a real helicopter aircraft, it would be a needless struggle to regain control of air space in our beloved game/simulator.
There are two approaches to simulating flight in computer games. One is to simulate the machine itself. In those you yourself are put in front of the more or less accurately simulated cockpit of the aircraft, and let the truth be said: if you actually get to the virtual sky and do something - other than crashing - it's because it was not well simulated, or you're a real pilot - and even so there is the posibility of crashing because of lack of feedback from the machine.
The other way is to simulate what a real pilot would feel under flying conditions. The aircraft you have to control is overly simplified to compensate your lack of real training - which take years and millions of dolars invested in you by the military. This way what you are simulating is the experience of an experienced pilot, you are very aware that flying real aircrafts must be very much difficult, but once you're on the batlefield - or over it - you'll get very realistic feelings. In other words, by eliminating the very thing that differenciates you from a trained pilot, you can have a pleasant and rewarding experience.
OFP was so great at it, that took me away of Longbow and Enemy Engage and allowed me and many others the possibility of coming close to what real pilots feel under combat situations.
So to sum it up, you are not learning to fly by any means, you are only learning to know what to expect from your input controls in this new - and wrong - twist of ArmA. Right now Arma is not doing anything right, not the first approach, not the second. It is not simulating the real responses from the real helicopter aircrafts, but it is not allowing you to take to the skys as experienced pilots of real life would do it either.
Just my two cents, about the most dissapointing part of ArmA, in my opinion.
Cheers.
