2: Un-plug the connector to the motor
arm you wish to change.
3: Using your Phillips screwdriver loosen,
but do not remove, the screw located on
the top of the control board. You only need
to turn it out about three turns or so to free
up the arm.
4: Grasp the arm and pull it from the main
chassis.
Install the new arm and re-tighten the
screw. DO NOT OVER TIGHTEN. Plug in the
power wire to the motor and replace the
body.
Happy flying from the Heli-Max™ team!
