Grilled wings are phenomenal. I've tinkered around with different methods on my OTG and found the way I like them best are heavily rubbed, keep the two pieces together for easy flipping, setup grill for indirect grilling at 375, do a slight sear first, indirect grill, and finish with a reverse sear. I like mine cooked more with a good char. I then cut them in separate pieces when I take them off, leave some with just rub and sauce the rest.
