Disassembly

1. Remove the screw (A) and spinner (B) from the collet (C).

2. Remove the spinner nut (D), propeller (E), spinner backplate (F), backplate

(G) and collet from the motor shaft (H). You will need a tool to turn the spin-

ner nut.

3. Remove the 3 screws (I) from the cowling (J). Carefully remove the cowling

from the fuselage. Paint may keep the cowling attached to the fuselage.

4. Remove the 4 screws (K) from the motor mount (L) and the fuselage.

5. Disconnect the motor wires from the ESC wires.

6. Remove the 4 screws (M) and motor (N) from the motor mount.

Assembly

Assemble in reverse order.

• Correctly align and connect the motor wire colors with the ESC wires.

• The propeller size numbers (12 x 4) 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.

Not all wiring shown.
