Foreword, notes on the building instructions
Many thanks for your decision to purchase this robbe product.
These models are only suitable for modellers with a certain level of expe-
rience and skill, and for this reason the building instructions have delibe-
rately been kept concise.
Some procedures are only sketched-in, and should be considered sim-
ply as guidelines and sources of inspiration.
The construction of the four models is identical. We have taken the
"Dillusion" as our example in the illustrations, but the procedures also
apply to the other models.
The model should be assembled as shown in the stage photos, which
also reflect the correct sequence of assembly. The text instructions only
point out areas where particular care has to be taken.
You will find safety notes in the appendix to the instructions; please
observe them at all times.
The radio control system
To fly the model you will need a radio control system with at least four
channels, three small servos and a BEC electronic speed controller.
Notes on using EPP
EPP is a virtually indestructible plastic material which can be cut using a
sharp modelling knife.
All joints involving EPP should be made using robbe Speed-Extra (cyano-
acrylate, "cyano") and activator spray.
The servos are held in place with a little epoxy so that you can remove
them at any time if they require maintenance or repair.
We recommend that you trial-fit the components and carry out any trim-
ming required before reaching for the glue. Only glue the joint when you
are confident that the parts fit snugly.
Notes on the power system and battery
Prepare the motor unit and speed controller ready for installation by fit-
ting the appropriate connectors to them. Read the instructions supplied
with the speed controller before fitting the battery connectors; take care
to avoid reversed polarity.
Assembling the model
Preparation, Fig. 1
- It is important to determine the position of the servos and receiver at
this stage in order to avoid unnecessary extension leads.
- Connect the servos and controller to the receiver and lay them on the
fuselage as shown.
- The distance between the output arms of the rudder and elevator ser-
vos and the tail end of the fuselage (pushrod length) should be no more
than 190 mm. Position the aileron servo in the rear area of the wing
saddle as shown.
- Mark the position of the components on the fuselage. Extend the servo
leads if necessary.
Pushrod assignment, Fig. 3
- a: Wire elevator joiner
- b: Aileron pushrods
- c: Rudder and elevator pushrods
- d: Wire control surface horns
The aileron servo, Figs. 4 - 6
- Set the servo to neutral and fix it in the fuselage using a little epoxy.
The wing, Figs. 7 - 17
- Cut a clearance opening for the aileron servo according to its position
in the fuselage.
- Offer up the wing panels to each other, but do not glue them together.
- The next step is to mark the position of the wire braces: lay the braces
on the wing at the thickest point of the airfoil, top and bottom. Cut
channels 3 - 4 mm deep in the foam, press the braces in one wing
panel and glue them in place.
- Fit the prepared wing panel in the fuselage opening (half fuselage thik-
kness).
- Offer up the second wing panel and align it carefully.
- Glue the wire braces in the second wing panel.
- The wings can now be glued to the fuselage. Take care to keep the
parts central and at right-angles to the fuselage.

The tailplane, Figs. 18 - 21
- Cut the slot for the wire joiner "a" in the underside of the elevators: it
should be 4 mm deep and positioned 5 mm from the hinge line. Press
the joiner into the recess and fix it with cyano.
Installing the tail panels, Figs. 22 - 25
- Slide the tailplane into its slot, align it parallel to the wing, and glue it
in place. Glue the fin to the fuselage at right-angles to the tailplane.
Installing and connecting the rudder and elevator servos, Figs. 26 - 31
- Cut recesses for the servos in the previously marked positions.
- Glue the wire control surface horns "d" in the rudder and elevator. Glue
the prepared servos to the fuselage using a little epoxy. Connect the
pushrods "c" to the servos.
- Set the servos to neutral, and tape the control surfaces at centre. Cut
the pushrods to length and connect them to the horns using pieces of
heat-shrink sleeve. Carefully shrink the sleeves onto the wire using the
tip of a small soldering iron. Apply a drop of cyano for extra security.
Connecting the ailerons, Figs. 32 - 34
- Connect the ailerons to the aileron servo as described for the rudder
and elevator. You will need to bend the wire pushrods "b" to the shape
shown.
Undercarriage, Figs. 35 - 40
- The wheels are retained with small pieces of heat-shrink sleeve on
both sides.
Electric motor, Figs. 41 - 46
- The correct sidethrust is obtained automatically when the doubler strip
is glued to the base plate.
- Check that the shaft spins freely when the motor is installed.
Receiver and speed controller, Fig. 47
- Cut recesses in the fuselage for the speed controller and receiver, and
press them into place. Cut narrow channels in the fuselage and press
the leads and the receiver aerial into them as shown.
Undercarriage fairings, Figs. 48 - 50
- Fit the wheel spats and align them carefully; make sure there is suffi-
cient ground clearance. Cut slots in the leg fairings, trim the ends as
required and glue the parts in place.
Engine side cheeks, Figs. 51 - 52
- Cut air ducts on the inside of the cowl cheeks, hold them against the
fuselage, and check that the motor is free to rotate. Glue the fairings
to the fuselage, deploying the motor wires in one air duct.
Battery position, balancing, Figs. 53, 55
- The Centre of Gravity (C.G.) for each model is stated in the side eleva-
tions on page 12.
- Temporarily fix the battery in place with rubber bands or adhesive tape.
Mark the correct CG position and support the model at the marked
points. Adjust the position of the battery until the fuselage remains
level when balanced in this way.
- Cut a recess in the fuselage to suit your battery; it should be a rea-
sonably tight push-fit, so that it cannot fall out accidentally. Do not
connect it at this stage.
Setting the control surface travels, Fig. 54
The basic control surface settings are the same for all four models.
After the initial test-flight you may wish to make minor adjustments to
suit your flying style.
- Switch the transmitter on, then connect the battery.
- Set the control surface travels as stated in the diagram.
- Check that the motor spins in the correct direction when you open the
throttle.
The first flight
Before test-flying the model be sure to read the sections in the Safety
Notes entitled "Routine pre-flight checks" and "Operating the model".
For the first flight wait for a day with flat calm conditions. The flying site
should be a large, flat, unobstructed field. The model can be hand-laun-
ched or taken off from the ground.
Keep well clear of the area around the propeller when carrying out any
work on the power system - injury hazard.
We reserve the right to alter technical specifications.
