I'm using JR 9XII on T-rex 450xl. After I set the machanic, I move on to radio setup and was wondering about ccpm epa setup. When I adjust epa on 3 servos for cyclic, do I leave the stick in neutral position while adjust epa on all 3 servos or I have to move the stick to maximum while adjusting?

I also have another question for epa on rudder servo. If I adjus epa rudder servo (both direct connection to receiver and via gyro), I end up having very slow response on rudder servo. If I leave the epa at 100% on both Left and Right, I have much quicker response on rudder servo. I'm using gy240 gyro. What happen here?
