Bristol M1C build

Hi all.I,m new to rc this past year,have a sig LT 40 that I built ,then modified,clipped wings ,less dihedral,now a beginner sport plane.I,ve decided to try my hand at scratch building and have started on a BristolM1C.Drawing my plans from windsock datafile 3 views scaled up to 1/6 scale.RCV 60 SP for power.Everything was going fine till I read about wash out.The wing has a flat bottom profile,kind of a thin clark y.What I need to know is,do I need to add wash out to this shape of wing? If so ,how much? all so, On the full size plane the wing was set at 0 deg incidence.I understand that clark y starts to lift at - 1.5 deg,will 0 deg be realistic to use on my plane? Thanks Guy.

Tom,thanks for the answer.Any other tips you can give me? Do you use aileron differential ? Do you use flying wires to keep the thin wing where it,s supposed to be ? Any info you can pass along is greatly appreciated .Your plane is very sharp! Guy.

Tom,Thanks for the info. Photo is great.You have a lot of detail in your plane that I had not noticed in your other photos.Any suggestions on what to use to make a sturdy and safe spinner? Guy.

Spinner is fabricated from a recessed light fixture's reflector......special starter is self explanatory

Hmmm,Maybe I can find a small light fixture to use,my plane is a bit smaller than yours.The starter cone is great! Thanks for the help and shareing your ideas.Guy.
