Depends on what your end goal is. With the semi symmetrical airfoil you will gain some speed. With the incidence you mention you will still maintain a fair amount of positive stability meaning the airplane will pitch trim at a narrow speed range. If that is what you want then great. If not, set the wing to zero as it will still generate enough lift to support the models weight but be more “ trim constant “ which would get even better with a CG at 30% to 33% and a couple degrees of down thrust.
