I dont know if everyone knows this, but if you use a mix, rudder as master and giro as slave, you can keep it in heading hold and as you move the rudder stick it will take the gain setting down to what ever you set your mix at. It will give you a piro rate that you can"t keep up with and as you start to return the rudder stick to center your gain rate returns also. I had to go + % with left stick and - % with right stick. I"am using a super 8 futaba radio I seen a video of a pro that had a piro rate that was super fast and this is the only way that I know that he could do this
