Hi,
At the moment I am studying the possibility of doing an early British jet (Gloster E-28). I notice that the plane had a positive stab incidence of 1.75 degrees. The plane seems to have a long tail moment which might have necessitated a lifting tail. Wing incidence was 1 degree positive. Would it be beneficial to emulate the real thing or should I stick to 0-0 tail incidence?
Moreover, why would it be beneficial for the real plane to have a positive stab incidence but not for the model?

Would appreciate your input as this has always been a burning issue at the back of my mind.

With thanks.

Reuben
