Smoked Chicken Legs?

[Scotty Dog]

I have four racks of legs in the smoker today.  I pulled the skin off and rubbed them in Jan's Spicy Rub.  I then bagged them and left them in the fridge overnight.  My plan is to smoke them for 3 hours.  I have the 6 rack digital and left the temp setting at 280.  After 1.5 hours the temp is at 195 and the vent is wide open.  Outside temp today is 32.  Should I foil the legs after the smoke and slow cook to keep them from drying out?  Do I need to rotate the racks during the smoke?  Thanks for any advice.

With that amount of meat I would rotate the racks front to back and top to bottom and use the top four slots.
