I load my sns with super hot coals, vents wide open and roast indirect at 425-450F.
For chicken quarters here is my flip schedule
20 mins skin up (crisp up the skin really good)
Flip
10 mins skin down (cooks the underside well)
Flip
10 mins skin up again (reprise the skin to finish)
I do a simple rub down with a light coat of mustard and nice even coating of your favorite seasoning, it comes out almost with a naked fried texture. Family favorite for sure.
I don't see why you wouldn't be able to use a vortex. For wings I do 40 mins total, rotating the lid without lifting a quarter every 10 mins and they come out perfect every time without flipping at all.
Included a pic of my 26" loaded with quarters with this same meathod.
