 5. Position the cowl so it is around 1/16"–1/8"
(1.5mm–3mm) from the spinner backplate. Use
the cardstock to drill four 1/16" (1.5mm) holes
through the cowl into the cowl mounting tabs in
the fuselage.
 4. Slide the cowling onto the fuselage. Install the
propeller adapter onto the Outrunner shaft. You
may need to ream out the hole on your prop hub
to fit the prop adapter shaft at this point. Slide
the propeller onto the prop adapter shaft. The
spinner backplate and spacers may need to be
enlarged as well to fit the prop adapter. Slide
the spinner backplate and any needed spacers
onto the prop adapter shaft. Secure the propeller
using the prop adapter spinner and be sure it is
secure and tight.
