Adjust to suit before gluing in the skid with epoxy.
Do not
glue the Fin in at this stage. Ensure that the Tail
Plane can fit into the Fuselage slot and the Fin slot without fouling.
Wing and Aileron
We recommend building the entire wing with Aliphatic Wood Glue. It is generally fast setting and can be
sanded at the same rate as balsa
.
Cut each piece of webbing from the supplied sheet of 1.5mm x 75mm x 457mm (1/16” x 4” x 18”) as per the
spacing shown below, making sure that all the webbing is perfectly square. Each webbing piece should be
approximately 40mm high, for example cut 8 No. webbing pieces 75 x 40mm (3” x 1 9/16”), 2 No. at 45 x
40mm (1 3/4” x 1 9/16”) etc.
The webbing should sit on the front of the spars, do not glue in place at this time, just use as a guide for rib
spacing. Carefully cut the ribs from the Depron sheet.
Dimensions shown in mm
Pin the main and trailing edge spars 4.5mm x 4.5mm x 915mm (3/16” x 3/16” x 36”) to the surface. Use a
straight edge to ensure that it is completely straight and both parts are parallel. Mark the centre of the spar
and the centre of the centre webbing; pin the centre webbing to the spar and place each rib in turn working
equally on both sides, separating each rib with a webbing piece previously cut to size as directed in the
drawing above. Push the rib down onto the spar so that the rib is flush with the board. N.B. It is important
that the bottom of the rib sits flush with the spar. (Please note the internal light look different to those
photographed)
