 4. Position the horizontal fuselage on the main
fuselage, again making sure that they line up
at the front. Use a square at multiple points on
the fuselage from nose to tail to guarantee the
horizontal fuselage is square to the main fuselage.
Check square from both the top and bottom side
of the fuselage. Allow the CA to fully cure before
proceeding.
 5. Position the left upper diagonal brace as shown.
Use the alignment point in the photo to properly
position the brace. The brace will just cover the
holes when aligned properly. Also make sure it
is aligned at the front of the fuselage. The angle
of the brace will be 45° to the fuselage sides
and will be equal distance on both the horizontal
and vertical fuselage. Use foam-safe CA to glue
the diagonal brace to the main and horizontal
fuselage. Do not apply CA to the rear section of
the diagonal brace, similar to that of the horizontal
fuselage.
You can temporarily use the foam firewall to
locate and mark the angle of the diagonal
brace at the front of the fuselage.
Make sure to use a square on the bottom side of
the horizontal fuselage when gluing the diagonal
brace to the vertical and horizontal fuselage.
Make sure that while you are gluing the
diagonal brace to the fuselage you do not put
a lot of pressure on the assembly. You could
create a warp in the fuselage assembly.
 6. Use foam-safe CA to glue the left lower diagonal
brace as shown.
