Motor and propeller
Motor
Press the propeller into place on the back. Hold the back of
the motor to prevent the base from loosening. The propeller
does not need to be pushed in too hard, but should be
slightly stuck.
Propeller
Insert a rubber ring around the motor.
Press the motor into place and lay up the cable as shown
in the picture. The motor should be a good distance in so
as not to get in the way of the arm later.
