Thes tabs move opposite the movement of the control surface and lighten the pilots workload considerably. Most pilots will tell you that you use right rudder on take off to counter engine torque which is not quite true. The forces acting on the aircraft during the TO run are P-factor, Gyroscopic precession, and assymetrical thrust during the climbout. This is what you are countering with the rudder. These forces are especially pronounced on tailwheel aircraft. As far as the aircraft trying to roll because of engine torque you do not feel this thru the stick. Rudder in a turn is used to counter adverse yaw which is the high wing creating more drag than the low wing and trying to yaw the aircraft away from the turn. The high wing is developing more lift because of the down aileron hence more drag and that is what yaws the aircraft away from the direction of bank. Basically the rudder streamlines your turn.
Stick forces were terrible.Many pilots died from not being able to pull out of dives.One of the main complaints of BF109 pilots was that cockpits were so cramped that they couldnt use leverage to muscle the plane around and thats part of why it was a notorious handle at speed.
