E-flite Cessna 150 Aerobat 250 ARF Assembly Manual
Always balance your propeller. An unbalanced
propeller can cause vibrations to be transmitted
into the airframe, which could damage the
airframe or other components as well as
produce unwanted flight characteristics.
We recommend using the optional spinner
to enhance the looks of your model.
6. Slide the propeller on the adapter shaft of the
spinner. Place the washer on, then the nut. Do not
tighten the nut at this time.
7. Slide the assembly on the motor shaft. Position the
assembly so there is a small 5/64-inch (2mm) gap
between the backplate and cowling.
8. Use a 6mm open-end wrench to tighten the nut,
securing the assembly to the motor shaft. Check that
the backplate does not rub against the cowl. If it does,
loosen the nut, move the assembly forward, then
re-tighten the nut.
9. Place the spinner cone on the propeller. Use the
screw included with the spinner assembly and a #1
Phillips screwdriver to secure the cone in position.
Make sure the propeller is centered in the openings
so the spinner does not rub against the prop blades,
which could potentially cause them to fail.
10. Replace the battery hatch cover back on
the fuselage.
