Welcome. Many are going to tell you it's a steep learning curve, but it's cliche, and that doesn't really tell you anything. A good suggestion made to me was to get to know every fighter and then you can formulate how to counter them. You can do a lot to help yourself, and shorten the curve by meeting up with a trainer. If you put a post on the Help/Training page re: what you want help with and when you are available, they will help you get a good head start. I too came from a background of MSCF(s) and found there to be many differences, it may surprise you, it did me.
If you see me on and would like some help with initial type stuff, like setting up your cockpit views, etc. I'll try to help where I'm able. Basic fighter maneuvers % combat maneuvers are best left to learn from the expert trainers...
As mentioned the trainers page is a great place to visit and also in the beginning I found the Musketeers website (Aces High related info) to be very helpful.
Good luck.
