Isn't interesting that entry level RC Aircraft only have rudder and elevator

Funny that a full sized airplane would react the same way.

In a stall, you pick up the low wing with rudder, not aileron, that only
adds adverse yaw, more drag on the low wing, and fights the rudder.

Using aileron to try to raise a dropping wing in a stall
increases the AOA on that wing and can aggravate the drop, causing a
spin. That's the real reason for using rudder.
The roll couple when we add rudder has a lot to do with
wingtip vortices. The vortex costs some lift as the air flows off the
bottom of the wing and over the tip. Sticking a wing ahead interferes
with that and can improve the lift on that side.
