Test to make sure the Engine is pushed forward enough to give

clearance for the Spinner, by placing the backplate of the Spinner

against the Engine Thrust Washer. Insert a scrap of ply (the same

thickness as F1A) between the Backplate and F1B. If there is not

enough room, you will have to sand the Backplate (if it’s plastic)

or the face of F1A and F1D after the Cowl construction is

complete. A palm sander or similar tool would achieve this in a

balanced fashion. With the Engine in the right position on the

Mount, mark and drill holes for your Mounting Bolts. Install your

Fuel Tubing before you bolt/screw in the Engine.

Sheeting the Upper Cowl

First remove the Engine. Glue on the Upper Cowl sheeting and

sand the edges as was done with the Lower Cowl sheeting.

Like before, layer the corners of the Upper Cowl with

⁄16" sheeting.

Then trim to allow F1A to fit inside. Clamp and glue it in.

It may be necessary to add a thin strip of balsa around F1A in

order to fill the edge gap.

Sand the corner sheeting to match the round Fuselage profile -

done with the Hatch bolted in place. Sand the entire Fuselage,

Hatch, and Cowl after the

⁄16" sheeting is installed for the Cooling

Vent. If you are skilled with a palm sander, this process can be

done quickly and easily. A palm sander, however, should only be

used to sand the corner sheeting level with the flat sheeting. The

actual rounding process should be done by hand. It would be

good insurance to epoxy the inside of the Cowl before sanding.

Vent Sheeting

Failure to sand the

Fuselage to a round

profile (not 45˚ corners)

will result in added nose

ballast and a heavier plane.
