Note: Make sure to check the balance of
the propeller after enlarging the hole in the
propeller.
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.
6. Enlarge the holes in the cowl using a 5/64"
(2mm) drill bit. Secure the cowl using four
2mm x 8mm sheet metal screws. Snap the
spinner cone onto the spinner backplate once
the cowl is secure.
Hint: Use thin CA to harden the holes drilled
into the cowl mounting tabs. This will help to
prevent the screws from vibrating loose in flight.
