(I know I know try the darn game but hopefully someone is bored like me that can answer the questions).
Stalls: On takeoff if you pull back too hard "will" you stall and crash.
Yes, you will stall if airspeed is too low.
Takeoff: do you have to use your flaps and the "runway" like in IL2 you could cross the grass bumping around until your in the air when vulchers were around? (i didn't like that)
You can bump around on the grass, but unlike Il2, there are hangers and things that will get in your way before you really get the chance to get in the air. Staying on the runway is recommended.
View: while in combat are you only able to use cockpit view or can you pass the cockpit view and have makeshift crosshairs for an easier shot? (I didn't like that either)
You are always in cockpit in a fighter. Only bombers have an external view. You do have a zoom function that can get you a clearer sight picture, but its an on/off thing unlike Il2 where you can control the amount of zoom.
There are the [ and ] keys which physically move your head position, but are not the same as the zoom.
