Would recommend mixing the batter with ICE cold water or even shaved ice for extra crispy finish. This is essentially a tempura batter that you are planning. Drumsticks tempura! The batter may well burn in the airfryer even on lowish heat, as the drumsticks will take MUCH longer to cook than the batter. Would recommend par-cooking the chooklegs in the microwave in moist heat, then battering them for the airfryer.
