Preheat oven to 450 degrees. Line a large baking sheet with foil and spray generously with cooking spray.
In a medium sized bowl, whisk together flour, baking powder, salt and pepper. Set aside.
Pat chicken as dry as possible and trim any excess fat, leaving most of the skin in tact. Coat each wing completely with the flour mixture.
Arrange chicken wings on the prepared baking sheet, close together but not touching. Bake for 30-35 minutes, turning wings over after about 15 minutes.
Meanwhile, in a small bowl, whisk together the honey, soy sauce, rice vinegar and sugar until sugar is dissolved; about a minute. Set aside.
Remove the baking sheet from the oven. Move the oven rack to the top position and switch the oven to a high broil. Brush a liberal amount of the glaze over each wing and place under the broiler for about 5-7 minutes (I usually give them two coats). Watch closely as they can burn quickly.
Remove the pan from the oven and brush with one more coat of the honey sauce.
Cool slightly before serving.
