Building the model
Stage 1, the basic wing structure, parts 1.1 - 1.13
Part No. Description Material Dimensions in mm No. off Notes
1.1 Bottom sheeting Balsa 1.5 2
1.2 Bottom spar Spruce 3 x 7 x 850 2
1.3 Root rib Plywood 3 die-cut parts 2
1.4-1.9 Wingrib Balsa 2, die-cut 2 each
1.10 Tip rib Plywood 3, die-cut 2
1.11 Trailing edge Balsa 6:4.5 x 8.5 x 820 2 each Asymm. taper
1.12 Bottom T.E. sheeting Balsa 1.5 x 15 x 820 2
1.13 Top mainspar Spruce 3 x 7 x 850 2
Note: it is not absolutely essential to glue the ribs to the bottom
sheeting over the plan (building board), provided that you mark
the rib positions accurately on the sheeting beforehand.
The instructions describe the construction of one wing panel.
The second panel is built in exactly the same sequence, but as
a mirror-image of the first.
- Mark the position of the ribs on the bottom sheeting 1.1 as
shown on the plan.
- Glue the bottom mainspar 1.2 to the bottom sheeting 1.1 flush
with the rear edge.
- Glue the root rib 1.3 and ribs 1.4 - 1.10 to the bottom
mainspar; check that they are exactly at right-angles when
viewed from the front.
- Ensure that the ribs make good contact with the bottom
sheeting. If necessary pin the ribs down to the sheeting until
the glue has set hard.
- Glue the trailing edge 1.11 to the trailing edge sheeting 1.12.
Check that the trailing edge strip is the right way up, as it is
not symmetrical, as shown in the detail drawing "Z".
- The following steps must be carried out directly on the
building board (plan).
- Pin down the assembled trailing edge 1.11, 1.12 over the
plan, leaving an equal overhang at right and left.
- Place the wing framework against it and glue the ribs in place.
- Pin down the bottom mainspar on the building board and glue
the top mainspar 1.13 in place. Check that the root rib 1.3 is
at right-angles to the bottom mainspar 1.2 - detail drawing
"Y".
- Remove the wing framework and sand the projecting parts
back flush with the outside shape of the ribs 1.3 and 1.10.
Stage 2, the basic wing structure, parts 2.1 - 2.8, HL
Part No. Description Material Dimensions in mm No. off Notes
„HL“ Jig strip Balsa 3 x 3 x 850 2
2.1 Outside doubler Plywood 3, die-cut 2
2.2 Centre doubler Plywood 3, die-cut 2
2.3 Top T.E. sheeting Balsa 1.5 x 15 x 820 2
2.4 Battery former Plywood 3, die-cut 2
2.5 Half-rib Plywood 3, die-cut 2
2.6 Spar webbing Balsa 1.5, overlength 24
2.7 Top sheeting Balsa 1.5 x 59 x 800 2
2.8 Leading edge Balsa 9 x 14 x 890 2
- Pin down the jig strip „HL“ over the plan, flush with the line of
the trailing edge strip.
- Place the wing structure over the plan and pin it to the building
board and the jig strip „HL“.
- Glue the doublers 2.1 and 2.2 to the ribs 1.3 and 1.10.
- Glue the top trailing edge sheeting 2.3 in place and cut off the
excess length.
- Glue together the battery former 2.4 and the half-rib 2.5 at
right-angles. Check that the half-rib 2.5 follows the wing
section correctly.
- Glue this assembly in place flush with the front edge of the
bottom sheeting. Use the extended lines on the plan as a
guide.
- Each of the spar webs 2.6 consists of two parts with the wood
grain vertical. Trim them to fit between the ribs 1.4 - 1.10 and
glue them in place. Do not fit webbing in the bay between ribs
1.3 and 1.4.
- Check carefully that the wing is resting squarely on the
building board. Glue the top sheeting 2.7 to the structure and
pin it in place.
- Allow the glue to set hard, then remove the wing from the
board. Sand back the ribs and the excess sheeting material
at the front face of the wing until you achieve a completely flat
surface for the leading edge.
- Glue the leading edge 2.8 to the wing.
- Sand the leading edge flush with the root and tip ribs and sand
to the proper section as shown on the plan.
