3.

Sand the stringers even with the formers.

Sand the fronts of the triangle corner stringers

so

they blend to the ply side doublers and the bottom
sheeting support.

4.

One at a time, remove the T-pins in the main

side stringers aft of former F6. Replace them at an
angle from the outside

so

they will not interfere with

the side sheeting.

During this time the

military was evaluating the YT-34 prototypes for use
as a trainer.

SHEET THE FUSELAGE SIDES

1.

Glue two 3/32" x 3" x 48" balsa sheets

together to make a 6" x 48" fuse

side

sheet.

After

the glue is dry, sand the sheets

so

they are flat,

even and smooth.

SHEET

'MAIN

FUSE STRINGER

True one edge of the fuse side

Hold

the side sheet on the right fuse side and mark the
wing saddle and corner stringer on the sheet. Trim
the sheet about 3/16" outside of the lines.

Note:

The side sheet will not reach all the way

back to the end of the fuselage. We will instruct you

to add a piece of leftover 3/32" balsa to the

rear later.

3.

Reposition the side sheet on the fuse. Mark

and trim the front bottom of the side sheet
above the bottom of the balsa front fuse doubler.

4 .

Test fit the side sheet and make any further

adjustments necessary for a good fit.

5.

Apply a bead of medium CA to the

ledge

portion of the side stringer from the

to

former F6. Working quickly, position the side sheet
on the ledge of t

he side stringer and press it into

position where you have applied the glue. After the
CA dries apply thin CA

to the side stringer and side

sheet aft of former F6 from inside the fuse. A long
CA applicator tip, such as the Pacer Z-Ends" with a
Teflon@ tube, helps you apply the CA just where
you need it.

6.

A little section at a time, carefully pry the

fuse side from the fuse side doubler and apply thin
or medium CA between the two. Quickly press
them together.

Do this until the fuse side is

thoroughly glued

to the side doubler.

7. Glue the fuse side

to the side stringers with

thin CA and hold them together until the CA cures.

You can really see how the bottom half of the fuse

will remain straight, true and flat (as flat as your
building board) when you remove it from your
building board!

8.

Return to step 1 and glue another side sheet

to the left fuse side the same way.

9.

Add pieces of leftover 3/32" balsa to extend

the side sheets to the end of the fuselage. See the

photo at step 11.

10.

Remove the T-pins and lift the fuselage from

your building board. Reinforce glue joints you
couldn't reach earlier or those that don't
look strong.
