OK Mike, no problem with taxi our field is grass, maybe the exponential slowed yours down a little, I do not have it in mine, I know the up aileron is not as effective as the lower one, whenever I use exponential I increase the slows. It was rainy here this morning so I did not get to try it with the throws I decreased again, maybe tomorrow, I have them down to about 1/4" each way and a little apprehensive about having enough for turns but I have rudder coupled in and can always switch in high throw if I need to.
