9. FAQ
How do I replace the propeller blades or propeller adapters if
they are damaged?
1) Prepare two propeller blade screws (M6×22 hex cap),
four propeller adapter screws (M3×11 hex cap), and four
propeller washers.
2) Apply threadlocker to the screw holes on the motor and the
propeller adapter.
3) Assemble the propeller and tighten with two propeller blade
screws (M6×22 hex cap) so that the blades can fold smoothly.
Mount the propeller onto the motor and use four propeller
adapter screws (M3×11 hex cap) to secure the propeller.

Ensure the screw is secured tightly for the threadlocker
to be effective.
Ensure the threadlocker is completely dry and solid before
flight to prevent the propeller from flying off the motor.
Motor Rotor Inertia 302 kg·mm 2
Total Rotor Inertia (Propeller Included) 3408 kg·mm 2
Torque Constant* 0.0790 N·m/A
Line-to-Line Inductance** 41 - 50 μH
Line-to-Line Resistance 60 mΩ

* The Back-Electromotive Force Constant and Torque Constant may vary
when the motor current is strong. The values provided mainly apply to when
the motor current is under 20 A.
** The Line-to-Line Inductance was measured with a current frequency of 1 kHz
in an RLC circuit. It varies periodically as a function of the rotor position.
