You will find AH is not "RR" like AW had. It will be very hard on the learning curve, even if you've flown other games before. I came in from WB and other flight sims and AH was no cake walk.
I suggest reading the help forums, trying the offline before online (your trail doesn't kick in til you go online for the first time, it'll save you 2 weeks free), and go to the TA (Training Arena) for help with the basics.
But, no matter what else you do, above ALL ELSE, go into "Flight Options" and UNCHECK "stall limiter" -- too many people leave this on and have to go through the entire learning process again later as they turn it off.
