6. Test fi t the fi n and stab into the fuselage.

7. View the model from behind to see if the stab is parallel
with the wing. If it is not, sand the
bottom
of the stab saddle
on the high side of the stab and the
top
of the saddle on
the low side until the stab aligns with the wing – it shouldn’t
take much sanding and proceed in small increments. Once
the saddle is adjusted all that should be required is a small
amount of weight to hold down the high side.

8. Make certain the trailing edge of the vertical stabilizer
aligns with the aft end of the fuselage. Otherwise the leading
edge of the rudder will not contact both parts, causing a
hinge gap.

9. The stab is pretty much locked-in and self-aligned
with the fuselage, but there is a little free-play. If striving for
perfection, you could rotationally align the stab as follows:
A. Tie a loop around one end of an approximately 48”
[1200mm] non-elastic line. Fold a piece of masking tape
over the other end of the line. Mark a line on the tape.
B. Insert a pin into middle of the lip in the front of the fuselage
for the battery/fuel tank hatch. Loop the line over the pin.
