□
12. Install F-5A. Use some 1/4” triangle stock behind F5-A for added strength.
□
14. Laminate GMA and GMB, once again using the pins for alignment. Drill and install the blind nuts for the
landing gear and then install into the fuselage using Epoxy, add 3/8” triangle stock on all four sides of the
GM assembly.
□
24. Use a sheet of 3/32” balsa to sheet the aft bottom section from the landing gear to the tail post. Run this
material cross grain.
□
13. Add the 3/8” triangle stock to the top from F5-A to F8.
□
15. Install 3/8” triangle stock along the fuselage bottom from F4 to F8.
□
17. Install the five 1⁄4” square stringers, top and bottom between the firewall and F3.
□
16. Install the 3/16” stabilizer saddle doublers (SD).
□
19. Install the wing saddle doubler (WSD). Note that WSD is has two sections to it; there is a second layer to
it at the aft end. Plain this second layer of WSD to taper flush with FO-5 to flush feather at FO-4A.
□
18. Install the outer formers, FO-3, FO-4, FO-4A, FO-5A, FO-5B, FO-6, FO-7 and FO-8.
□
22. It’s a good idea to sand the out sides of the fuselage skins before installing. It’s a lot easier to do this while
they can be laid flat on the bench.
□
21. Before adding the fuselage skins, check your fuselage assembly. You may want to sand or plain the
edges of the assembly to provide more glue land for the skins at the edges. A couple passes with 120 grit
sandpaper should do the job.
□
20. Assemble the outer fuselage skins. Once again there is a left and a right. The outer fuselage skins are
assembled from three pieces.
□
25. Use a sheet of 1⁄4” x 4” balsa to sheet the top fuselage section from F5-A to the stabilizer saddle.
□
23. When installing the fuselage skins it is helpful to have a piece of 5/16” square stock to insert into the
pushrod exit to help keep things aligned at the aft end. There is a notch at the front that will engage a tab
on the firewall assembly to align the front. Apply a liberal bead of aliphatic resin glue to all FO formers
except the top portion of FO-3 from the wing saddle to the top. This section will be glued in a later step.
Apply a liberal bead of thick CA to the firewall and along the wing saddle. Apply a second application to
the firewall to make sure there is plenty of adhesive. Place the fuselage skin into position using the tab at
the front and the push rod exit slot at the aft end. Align the wing saddle and press into contact until the
thick CA cures. Do the same with the firewall area. Now using finger pressure, move along the top of the
fuselage and apply thin CA to the remaining fuselage skin. Move to the bottom of the fuselage skin and
repeat this process along the bottom. When completed, trim away the section of FO-8 that crosses the push
rod exit slot.
□
26. The hatch is constructed on the fuselage with the wing in position. Bolt the wing on and then place a piece
of waxed paper at F-3 and F5-A to prevent adhesive from making the hatch permanent. Install two 1/8”
dowels into FH-1. Round the ends so they will easily enter the holes in F-3. You will need to remove some
material from the bottom of FH-1 to get a good fit.
□
27. Pin FH-5 in position over F5-A with the waxed paper in between them, install
□
28. Measure back from F3, 3-1/2” and 9-1/4” and place a mark on top of the wing at these locations. FH-2 and
FH-3 will go at these locations.
□
29. Test fit HA-1 on both sides of the fuselage. You may need to trim or sand a slight angle at the bottom to
accommodate the wing dihedral. When satisfied with the fit, glue HA-1 to FH-1 and FH-5.
□
30. Install FH-2 and FH-3 at the locations marked earlier.
