if you go to servo travel on the tx, you can adjust the percent of throw. interestingly, on eflite umx planes, they say not to exceed 99%, or you can damage the linear servos.
you can watch josh explain it in his basic aura set up video. you should not adjust throws on the fly with aura, you should land and adjust them at the board.
i'm no expert, just following the instructions, and it worked well on my duster.
