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 movement. Always disconnect the battery from the

aircraft before handling the propeller.

• Follow steps 1 and 2 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 oscillate, 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.

Disassembly

1. Remove the spinner (A) from the spinner backplate (B), using a small

amount of force.

2. Remove the hex nut (C), washer (D) and propeller (E) from the collet (F).

A tool may be required to remove the hex nut.

3. Carefully remove 3 screws (G) and the cowling (H) from the fuselage.
4. Remove the collet from the motor (I).
5. Remove 4 screws (J) from the motor mount (K) and the fuselage.
6. Disconnect the motor connectors from the ESC connectors.
7. Remove 4 screws (L) and 4 washers (M) from the motor mount and motor.

Assembly

Assemble in reverse order.
• Correctly align and connect the motor wire colors with the ESC wires.
• The propeller size numbers (11 x 8) must face out from the motor for correct

propeller operation.

• A tool is required to tighten the hex nut on the collet.
• Ensure the spinner is fully connected to the spinner backplate for safe

operation.

We recommend removal of the propeller before any radio system setup

or transport of your aircraft.
