Yeah..my intructor use to slap my hand when I put it on the left stick.
One stick at a time.lol
It was to earliy at that stage for me to make it look scale during banking.

The only time I use the rudder in the earily stages was only when the model was on the ground.

And when I was first allow to use the rudder....it wasn't during banking.
It was slight input to correct my flight path when pratice making a stright path over the runway 2-3 mistakes high.

The wake up the left thumb or left stick usage... I simply practice doing a stall truns, practice letting off
the throttle once I get to top of a loop, or do snap rolls 2-3 mistakes high. None these manuver
require precision input of the rudder..but to simply get me using the left stick agian.
