Dear Customer,
Congratulations on your choice of a factory-assembled model air-
craft from the robbe Modellsport range. Many thanks for placing
your trust in us.
Sequence of assembly
Please study the illustrations and the brief instructions to obtain a
clear understanding of the individual stages of construction.
The model can very quickly be completed, ready to fly. Please read
right through these instructions, the separate information sheets and
the Safety Notes before attempting to assemble and fly the model,
as this will make it much easier to complete the tasks required.
We constantly strive to update our products to reflect the latest
developments. You can find details of technical improvements,
updates and revised documentation on the Internet by calling
up the appropriate product description at our website: www.
robbe.com.
All directions, such as "right-hand", are as seen from the tail of
the model, looking forward.
Notes regarding the radio control system
For this model you require a computer radio control system with
at least six channels. This will enable you to adjust control surface
travels, servo neutrals, servo direction and Expo at the transmitter.
We particularly recommend 2.4 GHz systems.
Separate servos are employed to actuate the two ailerons.
The receiving system is powered by the speed controller's integral
BEC system.
Before you start construction, ensure that your receiving system
components will fit in the model where shown.
If you intend to install system components other than those we
recommend, you can still follow the same basic arrangement. You
may need to make minor adjustments to compensate for differences
in component sizes.

Assembly and operating instructions
Fokker DR 1 ARF
Set the servos to neutral from the transmitter (transmitter sticks and
trims central) before installing them.
Remove any output discs or levers from the servos.
Before flying the model always move the throttle stick to the "motor
stopped" position before switching the transmitter on. Only then
connect the flight battery.
To switch off, first disconnect the flight pack from the speed control-
ler, and only then switch the transmitter off.
When installing or setting up the receiving system componen-
ts, including the speed controller and motor, be sure to read
and observe the instructions supplied with them.
You should also read right through the instructions and safety
information supplied with the battery pack and charger before
using these items for the first time.
Glued joints
All parts must be trial-fitted "dry" (without glue) before you reach for
the adhesive.
Use abrasive paper to roughen all joint surfaces before applying
glue.
The text states which adhesive - epoxy, white glue, cyano - is
required for particular joints.
Notes on covering
Temperature fluctuations in transit may result in partial loss of ten-
sion in the covering film.
The film will become taut again if you play warm air from a heat-gun
over the slack area, and rub the film down smooth.
Servo wells, attachment points, hinge slots and holes are concealed
by the covering film. You can locate them by feel with your finger-
tips, and remove the covering film over them.
At a few areas the film covering has to be removed at joint areas;
take care not to score the underlying wood when you do this. We
recommend that you use a small soldering iron, and melt away the
film with the hot tip.
Painting the model, applying the decals
The model is supplied with the decals already applied. No painting
is required.
Take care that the decals do not come into contact with adhesive
(cyano), as this may damage the surface.
If you are aiming at a more realistic finish, a „weathering set" is
available which enables you to age the surfaces artificially.

Tail set
Note: the control surfaces are actuated by means of braided wire
pull-cables; the elevators are actuated by four pull-cables. Assign
the cables to the individual linkages, and cut them overlength.
Figs. 1 and 2
- Thread the two short pull-cables „SR" (rudder) through the two
slots in the tail end of the fuselage. Four slots are also present for
the four longer pull-cables „HR" (elevator).
- Group the braided wires together with tape and secure them
temporarily.
- Place the tailplane on the fuselage, centre it accurately, and fix it
temporarily.
Fig. 3
- Attach the elevators to the tailplane by gluing the hinges in the
slots. You can either use cyano-acrylate („cyano") or white glue
for this.
Fig. 4
- Glue the tailplane to the fuselage using white glue (PVA). Check by
eye that the tailplane is exactly horizontal and accurately centred.
- Install the rudder by gluing the hinges in the slots. Check that it is
exactly at right-angles to the tailplane.
Figs. 5 and 6
- Remove the covering film over the horn slots. Glue the horns in
the elevators and rudder using cyano or white glue.
Figs. 7 and 8
- The hatches on the underside of the fuselage are held in place by
locating tongues at the front and magnets at the rear. Raise the
rear of the hatches and lift them off.
