Ahh grilled hot wings, this I do more than fish...
It's a low and slow deal, sprinkle your rub on one side of the chicken then spray with Pam lightly and repeat on other side , put wings on hot grill , turn from high to low when you put them on , give them a nudge to keep from sticking while on the first side, getting seared from high heat, after a good color develops, flip and turn heat up for a few and lower till you have color again then place wings on upper level and cook for 45 min. To an hour, or to what doneness you want, I also drizzle and brush franks through this process for more grilled in flavor, when done ill leave some plain for the ladies that prefer ranch and then toss the rest in franks hot sauce-strait, add butter if you can't take the heat. This is a long process but you can suck everything right off the bone. : note: I can jam my drum part of the wing through the upper rack to get more done at one time, takes care of 4 people
I'll put up a pic when photobucket starts better
Here we go

The drums stick right in thru the grate
