4. With the pop-up tail boom assembled. Test fit the tail to the main fuselage assembly.
Locate the provided 1/8” aluminum rivet body and temporarily install through fuselage
and pivot as illustrated below. Note any significant friction that may interfere with the tail
smoothly rotating to near vertical within the fuselage and eliminate by evenly removing
thickness from the pivot and tail boom. Continue test and fit method until the tail rotates
with minimal friction when installed to the fuselage assembly. Caution: we do not want
the fit to be loose. Rotation should be free with no tendency to bind or grab yet not at the
expense of allowing side-side play in the pop-up tail boom assembly.
5. Final installation of your properly fit pop-up tail involves installing the 1/8” aluminum rivet
through the fuselage sides capturing the pop-up tail block and securing the rivet so that it
will not slip out in use. With the rivet head flush against the Left side of the fuselage use
your sanding block to reduce the Right side rivet overhang to 1/64” - 1/32” of overhang
beyond the ply fuselage side. Support the rivet head against your work table then from
the Right side place a #0 Phillips head screw driver centered within the rivet body.
Lightly tap the screw driver to flair the rivet body so that it will not slide back out of the
assembly. Note: being too aggressive with the flair will result in binding use the minimum
amount of force necessary to flair the rivet body. Finally apply a tiny drop of thin CA glue
at the to the surface where the outside edge of the rivet body and ply fuselage sides
meet.
