Archie and all, I'll weigh in. It sounds to me that the guys are wondering about roll rate.
True, for slow rolls, ie- 1 roll takes about 2 1/2-3 seconds, or longer if you extend it, rudder use is required. But for a single roll in Sportsman schedule, 1 roll consumes about 1 second give or take which is a medium-fast speed. What veterans call "normal" speed.
For this roll, rudder isn't really necessary and may actually drive you nuts trying to figure out where you are in the roll and what you're inputing on the tx. As Archie sez, if you find yourself in the latter situation, it will be counterproductive in the short term.
