11 REPLACING PROPELLERS
The X4's propellers are not identical. Each propeller is labelled with an A or B. When installing
replacement propellers, be sure to install as shown below. The X4 will not fly but will flip and
crash if the propellers are not installed correctly.
11.1 Remove Propellers
Hold the propeller, insert the U wrench under
the propeller, pull up and the propeller will
easily come off the motor shaft.
11.2 Install Propellers
Pinch the propeller hub, align the hole to the
motor shaft and press it straight down firmly
but gently.
Warning! Hazardous moving
parts. Keep fingers and other
body parts away
