Let me first state that I have NOT read the recipe for the flautas, so I don't know how they are handled.
Flour tortillas, yes, are pliable out of the bag, but, are even more pliable if they are toasted/heated in a hot dry skillet for a few seconds before working with it. If the fluatoas need to be rolled or shaped in any way, this will be easier if the tortilla is hot.
