The idea of landing a full-scale aircraft is to stall it
at a height of a some inches. The standard approach is
done with a speed of 30% above the stall speed. The aircraft
will sit on the runway with nose slightly up.

If you fly the aircraft into ground, it will bounce, and
the bounces will get progressively worse, unless somerhing
is done and quickly. The rule of my aerobatic instructor was:
'The propeller will get hurt on the third bounce'.
