Now glue the second fuselage side frame to the formers T04, T05 and T06, and to the central fuselage plate T09.

•

Place weights on the side frame to press the parts together. When the glue has set hard, the result will be a rigid

centre section which acts as the basis for the remainder of the fuselage construction.

Tip: if you sand over the joints carefully while the glue is still damp, the sanding dust combines with the adhesive to form

very strong fillets.

Draw a centreline on the building board: this acts as reference point for all the formers.

•

Hold the fuselage upright, place it on the centreline and weight it down carefully; check that it lies absolutely flat.

•

Glue the formers T03, T02 and T01 in place, followed by the formers T07 and T08.

•

Assemble the top fuselage sheeting from parts T15 and T16. Allow the joint to set hard, then glue this part to the

•

fuselage.

Glue short pieces of 3 x 3 mm balsa strip in the corner joints between the firewall T01, the fuselage sides and the top

•

sheeting. For the moment, glue the bottom strip to the former only; it will reinforce the bottom joint at a later stage.

Invert the fuselage and fix it to the building board again using pins and /

•

or weights.

Assemble the bottom fuselage sheeting from parts T17 and T18, allow

•

the glue to set hard, then glue it to the structure.

Carefully sand all four faces of the fuselage until they are completely

•

flat, then round off the corners of the fuselage slightly. Caution: the

fuselage sides project at the top in the area of the tailplane mount;

these projecting parts must not be sanded off, as they later form the

support for the tailplane.

The tailplane mount consists of a balsa in-fill piece, which can be cut

•

from a piece of scrap material from the machine-cut sheets, and the

plywood part No. 27. The rear edge of the plate should end flush with

the rear edge of the projecting fuselage sides.

The tailskid is a sandwich consisting of a central plywood core (S16),

•

with balsa parts (S17, S18, S19 and S20) glued on both sides.

Assemble the tailskid as shown in the drawing, and glue the joints.

•

The skid should be sanded to final profile before it is glued to the underside of the fuselage. Take care to install it

•

exactly at right-angles to the fuselage centreline.

The detachable hatch on the underside of the fuselage consists of the hatch cover T22, the front tongue (parts T23

•

and T24) and the latch retainer No. 24 (machined GRP part).

Assemble the hatch cover as shown in the drawing: the front edge of

•

the doubler T23 should end flush with the front edge of the hatch cover.

You will find a slot in the fuselage former T04 to accept the tongue T24.

The hatch cover is held in place by a spring-loaded metal latch. Drill a 5

•

mm Ø hole for the latch and glue it in place by applying 5-minute epoxy

on the inside of the fuselage.

Drill a 3 mm Ø hole in the GRP part to accept the latch pin. Take your

•

time over measuring the dimensions for this stage, to ensure that the

parts fit accurately.

The hatch covers on the top of the fuselage are assembled as shown in

•

the drawing. Each one features a locating tongue at one end and a

retaining screw at the other.

The final stage on the fuselage itself is the installation of the white snake outer sleeves for the rudder and elevator

•

linkages: cut small slots in the fuselage just forward of the rudder and elevator. Fit the snake outers, and glue them

in place at both ends and at two or three points between the extremes.
