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
shaped at the same rate as balsa
.
Cut each piece of webbing from the supplied sheet of 1.5mm x 100mm x 915mm (1/16” x 4” x 36”) as per the
spacing shown below, making sure that all the webbing is perfectly square. Each webbing piece should be
approximately 52mm (2 1/16”) high, for example cut 8 No. webbing pieces 100 x 52mm (4” x 2 1/16”), 2 No.
at 25 x 52mm (1” x 2 1/16”) etc.
The webbing should sit on the front of the spars, do not glue in place now, 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 ¼ 6mm x 6mm x 1220mm (¼” x ¼” x 48”) 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.
