for your plane to stay afloat the rudder will always need to be pointing toward the top of the plane. I first learned rudder from pushing toward the back of the plane if i could see the canopy or toward the front of the plane if i could see the bottom of the plane. Now a days my fingers do their onw thing. I think its like pushing under the low wing to level a plane coming towards you. After a while it just happens and you don't even think about it. But i always come up with a way to push toward something in my efffort to learn something. i push toward the low wing in the T-roll (with rudder) when a plane has it back side to me, as this is were most struggle in learning to T-roll. ........
