1.1
The outer fuselage side walls are stuck together using outer parts R-01o and R01u for the right side of
the fuselage and R-02o and R02u for the left side of the fuselage. To that end, the glued joint is
pressed together and fixed in place using a strip of adhesive tape. On the opposite side, a little white
glue or balsa cement is pressed into the glued joint. Please do not use low-viscosity superglue.
1.2
Then the inner parts R-03 are stuck on. Please note that this will produce a left part and a right part
and that the outlets for the Bowden cable tube are in different positions.
1.3
The main bulkhead R-04 is glued onto the reinforcement R-05 at right-angles. In the same step, the
magnetic holder comprising of parts R-08 and R-09 is completely stuck together.
1.4
Now, one of the sides of the fuselage is placed flat on the building board and the bulkheads R-04 and
R-05 (facing backwards) and R-06 and R-07 (with magnet holder R-08/R-09) are glued on at right-
angles. The second side of the fuselage is pressed and stuck on directly afterwards. The entire com-
ponent must be left to harden properly.
1.5
The fuselage is ground flat on the lower edge and fixed onto the building board so that it is flat.
1.6
Now, the entire surface of the two layers of the engine bulkhead R-10 are stuck together and this is
glued on right at the front of the fuselage. When pulling the pieces together, make sure that the fuse-
lage is not misshapen and that it is also pressed together evenly.
1.7
Bulkheads R-11, R-12 and R-13, terminal bulkhead R-16 and resting board R-14 are prepared. Drive-
in nut R-15 is glued onto the resting board R-14 with epoxy resin.
1.8
The bulkhead R-13, the terminal bulkhead R-16 and the resting board R-14 are stuck together to form
a single unit. In doing so, make sure that the boreholes that guide the Bowden cable tubes in bulkhead
R-13 are located opposite (!) the exits in the sides of the fuselage at different heights. In addition, the
adhesive flange of the drive-in nuts must be located inside the fuselage.
1.9
The bulkheads are stuck between the sides of the fuselage, starting from R-11. The sides of the fuse-
lage can be pulled together using paper tape. When the bulkhead unit consisting of R-13, R-14/R-15
and R-16 is inserted, the end of the fuselage becomes correctly aligned. Finally, bulkhead R-17 is
glued onto the tailplane bearing. This is where the fin will be constructed in a later step.
1.10 Bowden cable tubes R-18 are stuck in using balsa cement or 5-minute epoxy. Adhesive must be ap-
plied on the inside and outside on each bulkhead and at the exits on the end of the fuselage.
1.11 The panelling for the back of the fuselage R-19 is made of two parts put together in the middle. Before
it can be stuck on, the entire outside must be covered with parcel tape. This prevents it from breaking
later when bending around.
1.12 To get a good adhesive surface for the panelling, the edges on the fuselage are bevelled to approx. 3
mm wide using the knife.
1.13 The panelling is now stuck on in its own step. The centre line is clearly visible by means of the joint
edge. With several adhesive strips, the panelling is pulled over the bulkheads and both edges of the
fuselage. Before it is removed, make sure that the panelling is not twisted, as otherwise there will not
be enough material protruding.
1.14 Next, close the rear fuselage base. Tail skid R-21 is glued onto base plate R-20 at right-angles. The
front edge of the base plate (3 mm), to which the panelling (1.5 mm) connects in the next step, must
be ground down to ensure a clean transition.
1.15 Rear fuselage base R-22 is cut from the balsa wood board in segments and stuck on. It is very impor-
tant that the fibre direction runs across. Otherwise, the fuselage will not be torsionally rigid. The panel-
ling is stuck on up to the bend of the fuselage edge.
1.16 The front fuselage base R-23 is a laser-cut part and is stuck on. Based on the shape, you can check
again that the front part of the fuselage has actually been pulled together evenly.
1.17 The edges of the panelling are ground so that they are flush with the sides of the fuselage, but are not
yet rounded.
1.18 The removable fuselage cover on the upper side of the fuselage consists of base plate R-27, bulk-
heads R-28, two bulkhead covers R-29 and R-30 and the two-part panelling R-31.
1.19 The base plate is placed on a flat surface and the four bulkheads are stuck on at right-angles. In the
same step, the panelling is stuck in the middle, as already done on the sides of the fuselage. Again, to
ensure that the adhesive strip can be removed cleanly, do not use superglue. The 80 mm at the front
run apart from one another starting at the cut and are only brought together when stuck onto the
frame.
1.20 Once again, the panelling is stuck onto the outside using parcel tape to prevent it from breaking. The
cockpit cut-outs are left in – they are only removed after completion.
