Power Component Service
CAUTION: Always disconnect the fl ight battery before performing
motor service.
CAUTION: DO NOT handle the propeller, motor or ESC while the fl ight
battery is connected to the ESC. Personal injury could result.
Disassembly
1. Disconnect the fl ight battery before performing motor service.
2. Remove the screw (A) and spinner (B) from the collet (G).
3. Remove the spinner nut (C), propeller (D), spinner backplate (E),
backplate (F) and collet from the motor shaft. You will need a tool to turn
the spinner nut.
4. Remove the 4 screws (H) from the X-mount (I) and the fuselage.
5. Disconnect the motor wires from the ESC wires.
6. Remove the 4 screws (J) and motor (K) from the X-mount.
Assembly
Assemble in reverse order.
• Correctly align and connect the motor wire colors with the ESC wires.
• The propeller size numbers (12 X 5.25 V2) must face out from the motor for
correct propeller operation.
• A tool is required to tighten the spinner nut on the collet.
• Ensure the spinner is fully connected to the spinner backplate for safe
operation.
Propeller Maintenance
CAUTION: Always keep hands away from the propeller when a battery
is connected to the aircraft. When armed, the motor will turn the propeller
in response to any throttle stick movement. Always disconnect the battery from
the aircraft before handling the propeller.
• Follow steps 2 and 3 above to remove the propeller.
• Reassemble in reverse order.
• Ensure the propeller size numbers face toward the front of the aircraft.
Ensure the nut holds the propeller tightly without damaging the propeller.
NOTICE: If the propeller is not balanced, the aircraft may vibrate, causing the
stabilization system to not operate correctly and/or decrease the life of the
servos.
Horizon Hobby does not warrant replacement if the servos are used under
extreme vibration or the stabilization system is used with an unbalanced
propeller.
For more information, view John Redman’s propeller balancing video at
www.horizonhobby.com.
Tip: We recommend removal of the propeller before any radio system
setup or transport of your aircraft.
Tip: When replacing servos, we recommend tying a string to the
servo wire before removing the servo. This string allows you to easily
reinstall the servo and wire.
