I found the plane extremely easy to fly, for me I would brake then turn then as I am turning would start to accelerate - found that turned really quickly for me.
Managed to land the plane on the 2nd attempt - first go I smashed into a fireball on the floor.
All the time I didn't know I could drop bombs and several times must have touched a button that showed the overhead bomb view - didn't have a clue what was happening - but yeah plane was brilliant in the demo.
I also thought the draw distance was good and you get misty clouds in areas blocking your vision, can't wait to play the full game and hoping there are multiple planes to fly.
No, I am talking about the rudder on the tail of the plane, most games dont allow control of that. In a real plane its what you control with your feet.
On GTAV you use the r1-l1 to use it. It allows for cross wind adjustments, and makes for better adjustments when landing, especially if there are crosswinds.
