Introduction, notes on the building instructions
Many thanks and congratulations on your choice of a model aircraft
from the robbe Modellsport range. This is an ARF (Almost Ready to
Fly) model, i.e. it is supplied painted and largely factory-assembled.
This model is only suitable for modellers with a certain level of expe-
rience and skill, and for this reason the building instructions have deli-
berately been kept short.
Some procedures are only sketched-in, and should be considered
simply as guidelines and sources of inspiration.
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.
The radio control system
For this model you will require a radio control system with at least
three channels, together with two servos and an electronic speed
controller with BEC function.
Always set the throttle stick to the "motor stopped" end-point before
you switch on the transmitter; do not connect the flight battery until
you have done this.
When switching off, always disconnect the battery from the speed
controller first, and only then switch off the transmitter.
Assembling the model
Use epoxy or robbe Foam Speed (foam cyano) for all joints.
Installing the control surface horns
- Glue the reinforcing strip centrally to the underside of the elevator.
Drill a 2 mm Ø hole through it, and fit the M2 screw, plastic sprea-
der plates and nut. Screw the horn lug on the screw - Figs. 1 - 5.
- Install the aileron horns using the same procedure. Set the horn
lugs to the same height on both ailerons - Figs. 6 - 8.
Installing the aileron servos
- Trial-fit the aileron servo in the wing from the underside; trim the
servo opening if required. Glue the plywood strips in place as
shown. Cut away the top surface of the wing as required, then
install the servo - Figs. 9 - 11.
- Screw a clevis on each of the aileron pushrods, and form a Z-bend
in the other end.
- Connect the pushrods to the servo, and route them through the
slots in the wing fairing - Figs. 12 - 14.
- Place the wing and the wing fairing on the fuselage, and set it cen-
tral when viewed from above. Glue the fairing to the wing only.
Connect the aileron clevises - Figs. 15 and 16.
Tail panels
- Open the tailplane slots at the rear. Align the tailplane with the wing
when viewed from above and the front; glue it in place - Figs. 15,
17 and 18.
- Glue the tailskid in place. Open the fin slot to the rear. Glue the fin
in place at right-angles to the tailplane - Figs. 15, 19 - 21.
Elevator servo
- Install the elevator servo.
- Set the servo to neutral, and install the pushrod sleeve in the fuse-
lage. Screw the clevis on the pushrod, and fit the pushrod in the

fuselage from the tail end. Connect the clevis to the elevator - Figs.
23 - 27. Form the Z-bend at the front end of the pushrod and con-
nect it to the servo.
- Fit short pieces of heat-shrink sleeving on the motor cables atta-
ched to the speed controller, and solder a BEC plug lead to the
wires. Solder a matching socket to the battery cables attached to
the speed controller - take care to maintain correct polarity when
connecting the cables; read the controller instructions.
- Connect the speed controller and the elevator servo to the recei-
ver, then fix the receiver to the fuselage side using double-sided
foam tape - Fig. 28.
- Tension the receiver aerial to the fin.
Undercarriage and cowl, final work
- Fit the wheels and check that they rotate freely. Cut a slot in the
underside of the fuselage for the undercarriage. Check that the
undercarriage fits snugly between the two formers in the fuselage.
- Glue the undercarriage in place - Figs. 29 - 31.
- Fit the wing dowels and glue them in place.
- Fit the cowl on the model, position it carefully and attach it using
self-tapping screws on both sides - Fig. 32.
- Complete the pilot figure and dummy machine gun and glue them
to the fuselage as shown - Figs. 33 and 34.
- Fit the propeller and propeller driver on the electric motor; ensure
that they are firmly secured - Fig. 35.
- Fix the wing to the fuselage using four rubber bands - Fig. 36.
- Place the flight battery in the fuselage to check the model's balan-
ce; don't connect it at this stage - Fig. 37. Screw the hatch turn-
buckle in place - Fig. 38.
Balancing, Fig. 39
The Centre of Gravity of our Fokker is approximately 45 mm aft of the
root leading edge. Mark the CG position and support the model at
that point.
The model is balanced correctly when it hangs approximately level.
Adjust the position of the battery until the aeroplane balances as des-
cribed, then pack foam rubber round the pack to prevent it shifting.
Mark the position of the battery in the fuselage, so that you can easi-
ly replace it in the same position after removing it.
Checking the control systems, Fig. 40
- Set the transmitter sticks and trims to centre.
- The control surfaces should now be at neutral (centre); if not, adjust
the clevises to correct.
- Check the direction of movement (the "sense") of the control sur-
faces, and use your transmitter's servo reverse facilities if they are
not correct.
- Set the control surface travels as stated in Fig. 40.
- Check the direction of rotation of the motor shaft, then fit the pro-
peller.
Caution: during all these stages, i.e. when assembling, maintaining
and adjusting the model, keep well clear of the rotational plane of
the propeller - injury hazard.
First flights
Before attempting the first flight please read the sections in the
Safety Notes entitled "Routine pre-flight checks" and "Flying the
model".
Seek out a large, flat, open field for your flying site, and wait for a day
with little or no wind. The model can be hand-launched or taken off
from the ground.
The model must be launched directly into wind.
