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 4.5mm x 18mm x 915mm (3/16” x 3/4” x 36”) leading edge (LE) strip on to the front of the ribs. Pin
in place and allow to dry.
Cut the 1.5mm x 75 x 915mm (1/16” x 3” x 36”) leading and trailing edge sheet into two pieces each
measuring 1.5mm x 60mm x 915mm (1/16” x 2 5/16” x 36”) and 1.5mm x 15 x 915mm (1/16” x 9/16 x 36”)
Chamfer the LE as shown below before gluing on the 1.5mm x 60mm x 915mm (1/16” x 2 7/16 x 36”) LE
sheet and 1.5mm x 15mm x 915mm (1/16” x 9/16” x 36”) Trailing Edge (TE). The LE sheet should be glued
to the centre of the spar first, then when dry place glue on the ribs and LE and pin into position.
Un-pin from the board and repeat the sheeting process to the underside of the wing. Once completed cut off
any excess spar, leading, trailing edge and sheeting, leave flush with the end ribs.
Take the 1.5mm x 75mm x 457mm (1/16” x 3” x 18”) sheeting supplied and sheet across the 4 centre ribs to
both top and bottom of the wing, glue to the ribs. Cut a hole in the underside of the sheeting between the
two centre ribs to allow the servo leads to exit.
