1Cut each chicken wing at joints to make 3 pieces; discard tip. Cut off excess skin; discard.
2Heat oven to 425º. Melt margarine in rectangular pan, 13x9x2 inches, in oven. Mix flour, salt and pepper in large heavy-duty resealable plastic bag. Add chicken; seal bag tightly. Shake until chicken is completely coated with flour mixture. Place in pan.
3Bake uncovered 20 minutes; turn chicken. Mix barbecue sauce, pepper sauce, Cajun seasoning and cumin in medium bowl. Pour over chicken; toss until evenly coated with sauce. Bake uncovered 10 to 12 minutes longer or until light golden brown on outside and juice is no longer pink when centers of thickest pieces are cut.
