Propeller and motor check

Complete the following checks on your propellers and motor. If you answer 'fail' to any of these questions, report the issue to the chief pilot immediately. Take any relevant photos and include notes of the issues that you identify.
Check the lugs on snap-on propellers are not cracked at the base or have not broken off
If you have screw on propellers, check that they are not cross-threaded; and once installed check that they sit firmly proud with the motor
Bend them slightly to see latitudinal cracks
As you fix the propellers to the craft check that the motors are moving freely, do not rock in their housing and are free of damage
Ensure that the correct propeller is placed on the corresponding motor
Make sure that all motors rotate smoothly
Check motors are firmly seated and do not rock in the casing
Feel each of the propellers along the edges and across the blades for chips, nicks, or cracks
