One small suggestion, which works great for me.
I assigned the "Fire D" button (blue light thumb button) on the throttle side, to "Fire All" this allows better control of the joy stick side when aiming, as you do not get unwanted movement when pulling the trigger.
Try it, and you will notice how the trigger pull sometimes affects your aim.
With the fire button removed to the other handle, there is no chance to come off target by an erratic trigger pull.
