Removal: When the blade is damaged or needs to be
replaced, hold the propeller with a hand or the
provided auxiliary wrench, and remove by turning it in
the indicated "unlock" direction.
Make sure that the propellers are installed
•
in the correct positions, otherwise the
aircraft will not be able to fly normally.
Since the propeller blades are thin and
•
somewhat sharp, it is recommended that
users wear gloves during installation to
prevent accidental scratches.
