1. FUSELAGE

C
The fuselage is reinforced the same as on the
full-size with internal wire bracing.
No turnbuckles are needed.
Install the wires as shown in the drawings and
photos.
Important: to prevent distortion of the fuselage
do not over tighten the wires!
A slight tension is sufficient, the fuselage is not
a guitar... After a few attempts you will find
the right tension. Slightly loose wires have no
negative effect on the strength of the fuselage.

1) Fix one end of the wire as shown in drawing A
and photo B.
Don’t forget to insert a second ferrule to fix the
other end.
Note: aluminum ferrules are supplied in the kit,
as opposed to the steel ferrules on the prototype
shown in the photos.
2) To achieve the correct tension, make a 90°
bend in the other end of the wire, a millimeter or
two short of the distance between the lugs. See
drawing A and photo D.
3) Insert the wire completely and fully bend the
ends to 180°. Check that the tension is not exces-
sive. You can bend the stainless steel wire many
times without compromising its integrity, in any
case, there is ample wire supplied.
4) Attach wire completely as in the drawing C.
More than one wire can be attached to a corner,
see photo E.
NOTE:
Although the full-size Fokker had transversal
wires at each station of the fuselage, this is not
necessary in the model, as only the two transver-
sal wires behind the pilot seat are needed for
strength.

WING DRAWING
BUILDING BOARD 200 x 50 cm approx.
8 MM POPLAR PLYWOOD RIB SUPPORT
1) Place the wing drawing on a flat building board of approx. 200 x 50 cm.
2) Protect the drawing with a transparent sheet.
3) Nail the rib support on the drawing to build the wing jig as shown in drawing A
and B.
4) Protect each rib support with sellotape.
5) Fix the flexible plywood wing tip jig on the rib supports, use some self-tapping
screws.
6) Protect the border of the wing tip jig with sellotape.
7) Build the wing tips by laminating 6 cedar strips as shown in photo C.

INNER STEEL FITTING ON SPAR ROOT
WITH LUG FOR INTERNAL BRACING WIRE
OUTER STEEL FITTING ON SPAR ROOT
8) Mount the steel fittings on both sides of the spars (photo E) and remove the
wood following the shape of the fittings as in the drawing D.
9) Drill a 2.5 mm hole on the spar as in the drawing D.
10) Mount the wire attachments as in the drawings F and G.
11) Place a lime wood strip on each rib support and glue the trailing edge as shown
in the drawing H. On the first two ribs use a 2 mm ceiba plywood sheet (photo I)

Note: chamfer the ends of each strip to an angle of 10° approx. with sandpaper.

13) Position and glue the rear spar as shown in the photo J.
WARNING: Ensure that both fork ends are perfectly aligned at 1.5
mm distance from the root rib. Use a 8 mm diameter rod to align
as shown in the drawing K.
14) Glue in place the birch plywood root rib as shown in the photo
L and place the front spar against the rib without gluing it.
15) Mount the two compression members as shown in photo M.
