Aircraft drag coefficient and aerodynamic drag?


i'm desinging small aircraft (model) , i'm working on aerodyanmic drag. have deep camber, high lift, low speed airfoil. there formula use calculate drag on particular airfoil? know there standard drag coefficient formula being:

drag coefficient= 2fd on pv2a

fd= drag force
p= mass density
v= speed
a= referance area

referance area being planform because aircraft, , straight wing, there formula?

thanks.
