In my opinion, flaps (and ailerons) are sort of unnecesary or even counter-productive in Carrier.
Currently, winning models go into a prop-hanging "hover" mode of "flight" were full scale aerodynamics become irrevelent.
Real airplane fly slow filight at about 22-to-25 degrees AOA and flaps help. But modern prop-hanging Carrier planes fly at 60 degrees, so airfoils, flaps, etc, don't mean much.
