I am quite new but as is its pretty good. Attached manual. Read Read Read, I went into the tuning and softened the initial stick movements for (S) sport mode so when wanting to smooth out slow travel movements abruptness. Read about Expo: in the tuning.
Using Expo I also increased Roll sensitivity in (V) Video and S modes as I felt too much stick was required to get bring it on. I also took Dead Zone number down 2 digits.
