retracts for details on the correct installation and
plumbing of the retract units. Although a good

To locate the cutout for the retractable nose
gear use the panel lines etched on the fuselage.

Place some removable tape on the fuselage over
the location of the nose gear cutout; this will
protect the paint when cutting. Using the panel
lines as a guide, use a pen to mark the location
of the cutout on the tape. This will make the
lines more visible and the cut easier.

Using a sharp hobby knife, hobby saw or small
rotary cutting tool cut the opening for the
retractable nose wheel. Ensure you cut
completely through the bulkhead as shown in
the image below.
