Yeap don't worry about the rudder for now.

You're suppose to use the rudder to yaw, which will help you align better but as a newbie it'll complicate everything for ya.
Becuase you'll over think, over correct or move the rudder too much.
Which will actually make your model roll. Then you'll try to corect it with the rudder..only and it won't roll back fast enough
....becuase you're loosing speed...Speed is your Freind (wind blowing over your control surface)

Wings with higher diahidral will do that..Just read up on flight theroy a little bit and you'll comprehend .

As you practice making a striaght path over the runway more. 25"-50" off of the deck. You can practice making those little
input or corrections.

My instructor...would not allow me to land until I've had master my striaght flight over the runway and master my proceedure
truns from all directions at a slower speed.
Bascailly he was teaching me how to land 50' feet off of the deck. So i don't trip if i get in trouble...I add power to abort bad
approches instead of yanking on the elevator.


As you did with the airlerons.
The samething in a torque roll or hover...when the model's bottom is facing you....trun the rudder stick in the direction
the wing is dipping to level the model.

Practice doing a slow roll or a 4 piont roll with your trainer. To keep the model on a level flight path..you must apply rudder and elevator also
