As you install W2 take a piece of paper and roll into a tube to carry the servo wires to the centre section, this
is optional, but we Find this makes the installation look tidier. These need to be inserted as work proceeds
as it is impossible to insert after all the ribs are in place. Once the tube is in position wrap it with Sellotape to
seal the edge once in position.
Continue to place the ribs, you may find that the final rib is approximately 3mm (1/8”) short of the end of the
spar, cut the excess spar off later. Ensure that you place the correct rib in the correct position as per the
diagram above. Once dry, place the upper spar into position and glue in place. Glue the ribs in place, check
to make sure that the ribs are all vertical and at 90°. Once dry, glue the webbing in place.
Glue the 6mm x 25mm x 1220mm (¼” x 1” x 48”) leading edge (LE) strip on to the front of the ribs. Pin in
place and allow to dry.
Cut the 1.5mm x 100 x 1220mm (1/16” x 4” x 48”) leading and trailing edge sheet into two pieces each
measuring 1.5mm x 80mm x 1220mm (1/16” x 3 ¼” x 48”) and 1.5mm x 20 x 1220mm (1/16” x 3/4” x 48”)
20mm
Chamfer the LE as shown below before gluing on the 1.5mm x 80mm x 1220mm (1/16” x 3 ¼” x 48”) LE.
The Sheeting on should run from the centre of the main spar to the LE, if it sits 2-3mm back from the LE this
is fine as when you shape the LE it will remove this material anyway. The remaining 1.5mm x 20mm x
1220mm (1/16” x 3/4” x 48”) is used for the Trailing Edge (TE). The LE sheet should be glued to the LE first
checking the sheet bends to the centre of the spar, then when dry place glue on the ribs and spar pull back
into position and allow to dry.
