wing. If it is not, the following Expert Tip can be used to
slightly twist the fuselage.
Straightening a twisted fiberglass fuselage
Use a heat gun to heat the fuselage between the stab
and wing. Try to heat the fuselage evenly. Do not hold the
heat gun in one place. It does not require a lot of heat; the
fuse needs to be warm. Hold the fuselage in front of the
wing and in front of the stab and gently twist. Hold the
fuselage in this position until it has cooled. You may need
to twist it a few times before you get it in the correct
position.
10. Use a 1/8" drill bit to drill two rudder cable exit holes
at the front of the indentations, at the aft end of the fuselage.
11. Cut two 1-1/2" [38mm] long cable guide tubes from
the 6-1/2" [165mm] white plastic tube. Glue the cable guide
tubes in the holes drilled in the previous step. Allow the
tubes to extend out of the holes approximately 1/8" [3mm].
12. Fit the fin into the stab. From the aft end of the plane,
sight down the fin, checking that it is aligned with the
centerline of the fuselage. Mark the outline of the fin on the
stab. Then use the soldering iron technique to remove the
covering on the stab. Glue the fin into position using 30-minute
epoxy. Use a builder's square to make sure the fin is
perpendicular to the stab. Masking tape can be used to hold
the fin in position until the epoxy cures.
Install Servo & Battery Tray
1. Install the rudder and elevator servos in the servo tray
using the hardware that is included with the servos. You may
need to trim the servo mounting holes to accommodate the
brand of micro servos you are using. Note that the servo tray
has a wide side and a narrow side and which direction the
servos face compared to the sides.
2. Position the servo tray in front of the wing nut plate so
that the narrow end is towards the aft end of the plane. Make
sure that you can get to the servo mounting screws. If there
is space between the rudder and elevator servos and the
bottom of the fuselage, we recommend that you use a
sanding bar to sand a bevel on the sides of the servo tray to
allow the tray to set lower. This will leave more room
between the elevator and rudder servos and the aileron
