AH2 tries very hard to be as realistic as is possible while stil lbeing fun -- and that can mean major differences from flying "games." Remember that in real planes, lift -- the ability to fly -- comes from forward speed, air moving across teh wing.
Anything you do to change that flow from smooth, even currents can mess up your lift. If you try banking, or if you give the plane rudder, or nose up to climb - yuo better have extra speed on board to amke up for the lift lost.
Short answer -- be fast and you'll get away with more. If you're stalling and spinning every time, you're probably pulling up much too early, before the plaen ahs enough speed to do what you want.
Stall recovery is good practice, becasue once you'r efighting you WILL get into situations where you're on the very edge of losing flight control. Nose down, put stick in the center AND LEAVE IT THERE, Release rudder and wait for speed to build up enough that you're flying again.
With spin -- one wing has stalled befoer teh other one. Throttle down, neutral stick, opposite rudder (IE if your plane nose is spinning to r, give full L rudder), and elevator down (push stick forward). Continue these four until the plane recovers/
