OK I am learning bit by bit.
I think that I was not being clear I meant mid wing span wise not cord wise
but your clarification is useful to say the least.
So the cord is the line/distance between the leading edge and the trailing
edge so that in this instance the angle of incidence is cord 2.5 deg leading
edge up relative to the datum line which is the left windowsill. The
template is merely a method of measuring this - one could for example attach
a straight edge to Leading edge and Trailing edge and achieve the same
effect.
So the next question is roll trim...I am assuming this is a servo embedded
in the aileron connected to a trim tab in the ? right wing.
Anyone have any advice on this type of servo etc?

Graham thanks - so the idea is more one of the incidence being the same mid-
wing rather than a specific angle?

sorry, I was too brief again, (getting too lazy to type)
The effective angle of attack imho is more dependant on the relationship
between the center of the leading edge radius and the trailing edge than the
bit in between. this can be anything between a flat plate and a thick
ellipse and still have the same angle of attack. Lift is more or less
linearly related to AoA in the cruise. This is when a built in roll will be
most irritating. You will need roll trim, which is useful anyway to account
for assymetrical loading.
