Hi Rider,

Making a turn in an aircraft is actually more complicated than it looks.

You have to roll towards the desired turn direction (using the ailerons) then 'climb' into the turn, using the elevator, so that height is maintained.

Just the initial roll isn't going to change your direction (it will just roll and stay on the same path!) it's only when you give up elevator that you make the turn.

The rudder can be used to make a better, or more 'coordinated' turn. By that I mean just using aileron and elevator tends to make the plane yaw away from the turn (that is the top wing 'holds back' making the plane yaw out of the turn) and giving a small amount of rudder in the same direction as the turn helps to make it smoother by getting rid of this yaw.

Hope that helped!!

Good luck!
