Your copter includes normal propellers (unmarked or marked "SF") and pusher propellers
(marked "SFP" or "P"). The direction of each motor is shown below: add pusher propellers

Remove plastic rings from propeller package, select the one with the larger internal
diameter, and insert it into the back of the
propeller hub.
Add propeller to motor collet with writing
facing up in relation to the sky. Add metal
spacer and prop nut; tightly fasten prop
nut to threaded collet.
We recommend inserting a hex wrench
(2 mm) into the hole in the side of the
prop nut to get better leverage when
tightening prop nuts.

Making sure your copter's wiring is neatly secured is an important safety step.

Before flying, use zip ties to secure ESCs to the frame. Ensure that all wires are
secured so that they cannot become entangled in spinning propellers but are
not too tight around corners (no hard 90-180 degree bends) and do not pull on
the APM or other components. Always complete the pre-flight checklist before
takeoff (copter.ardupilot.com/wiki/checklist).
