Ok im trying to correct a small pull to the canopy on knife edge, and using the rud to ele function on the 12FG, my questions is how do I get it to come in with say a very small amount of stick movement 4 points slow rolls etc. The manual tells you how to set it up but not to adjust to the stick movement, just say see back of the manual for curve setting.

You set up the mix curve as "Point". Then you can put in the percentage of mix by setting in the rate at the desired point. You have 17 points you can use.
