Condor, if you roll out a notch of flaps, then another, until you have full flaps out, it significantly increases lif and decreases the wing dip. US planes are the easiest to land without a wingtip.
Now, a Ki84, or a Fw190... THOSE are harder! The flaps don't come out until you're almost stalled. Takes a bit of finessing, controlled stalling at nose high angles, etc.
