Gees way over my head. The EASIEST way to do it is use the good old L.A.R. method.(Looks about right)
When ever i see degrees listed for the angle i always start with
Ailerons 3/4inch with 25% expo
Elevator 1 inch with 25% expo
Rudder all i can get with 35% expo
Flaps 1 inch and work my way up from there
Always worked for me. Now if i wanted to get REALLY fussy i do have a Mitutoyo digital protractor 3600pro but never use it.
