when i use the rudder the plane/helicopter returns to the start of the turn

Then it follows that using the rudder while in normal, coordinated, unaccelerated flight causes the conditions so described.

 

They are still worth watching for the neophytes just joining us that don't really know a whole lot about "why" when it comes to the dynamics of flight. People do post-graduate work on the intricacies of the things discussed here. Look up Reynolds Numbers. Blow your mind, man.

 

 

Right. I'm thinking it has to do with vertical stability of the airplane. Either way, thanks for the vids.

When you push rudder, you induce beta - ie. Yaw AoA (as opposed to Alpha: Pitch AoA). This also causes one wing to fly slower, and the other faster, so one wing has more lift than the other and so you induce roll.

 

Let go of the rudder and, as you said, the plane 'weathervanes' back into as close to 0 beta as it can get.
