Preheat oven to 350°. In a bowl or shallow dish, combine the flour, salt and cayenne pepper; add the chicken pieces and turn to coat. Pour 4 tablespoons butter into a 13x9-in. baking pan; place chicken in pan, turning pieces once to coat.
Bake, uncovered, 30 minutes. Combine the brown sugar, honey, lemon juice, soy sauce, curry powder and remaining butter; pour over chicken. Bake until juices run clear, 45 minutes, basting several times with pan drippings.
