What max rudder throws are folks using for F3A? I'm just setting up my new plane, and to me it seems there would be some point at which more throw isn't doing you any good, just adding drag and creating weird coupling. 45' seems like a reasonable place to start, but is it a case of severely diminishing returns after say 30' or is it important up to 60'? Has anyone done any testing on this?

The underlying reason for the question is two fold. One, physically, I have just over 30 degrees throw as it sits, but can easily add more to the fin TE or rudder LE to get more throw. Second, I want to set the linkage for max resolution so I'd like to set the trade-off between resolution and leverage properly. Wasting resolution/leverage achieving throw that I don't need doesn't make sense.

Any advice on effective max throws welcome!
