Thanks for your advice. From previous designs I did have elevons on the main and a flying canard in the front. Without realizing the dynamics of canard aircraft I found the varying incidence of the flying canard caused the bad stalling tendencies.
So I will use about 30% of the area of the canard as the elevator and about 1/2 span of the main wing section as the aileron. I guess control throws and expos will be up to experimentation.
