Operating instructions - SKY EAGLE RTF FTR 2.4 GHz No. NE2009FTR
FUTABA Transmitter Ready, abbreviated to FTR, applies to selected models from the Nine Eagles range. These
models' transmitter and receiver work with the FUTABA S-FHSS code, and can also be operated with FUTABA
transmitters which can be operated in S-FHSS mode.
At present these are the following transmitters:
Skysport T4YF 2,4 GHz FHSS M2 1-F4074
Skysport T4YF 2,4 GHz FHSS M1 1-F4074M1
T6J-R2006GS 2.4 GHz FHSS, No. F4100
T-8J - R2008SB 2.4 GHz FHSS/S-FHSS, No. F4108
T18MZ - R7008SB 2.4 GHz FASSTest M2, No. F8073
T18MZ - R7008SB 2.4 GHz FASSTest M1, No. F8073M1
Binding the model to a FUTABA transmitter
This works in the same manner as described for the transmitter supplied in the set; see page 16. Please also read

Explanation of specialist terms:
Motor speed ("Throttle"): This controls the rotati-
onal speed of the motor. Stick forward = maximum
speed; stick back = motor off.
Rudder: This controls the model's attitude around
the vertical (yaw) axis, causing the aeroplane to fly
to the right or left.
Up-elevator / down-elevator: This controls the
model's flight attitude around the lateral (pitch)
axis. Stick forward = the model descends; stick
back = the model climbs.
Ailerons: This controls the model's flight attitude
around the longitudinal (roll) axis. Stick right = right
wing down; stick left = left wing down.
Mode 1: Function assignment of the control move-
ments relative to the stick movements.
In this case throttle and ailerons are controlled by
the right-hand transmitter stick, elevator and rudder
by the left-hand stick.
Mode 2: Function assignment of the control move-
ments relative to the stick movements.
In this case throttle and rudder are controlled by
the left-hand transmitter stick, elevator and ailerons
by the right-hand stick.
Dual-Rates:
Switchable travel reduction for control movements.

Be sure to read these Safety Notes before you assemble your mo-
del. Always keep to the procedures and settings recommended in
the instructions.
If you are operating a radio-controlled model aircraft, helicopter, car
or boat for the first time, we recommend that you enlist an expe-
rienced modeller to help you.
Safety Notes
Radio-controlled models are not toys in the usual sense of the term.
Young persons under fourteen years should only be allowed to operate
them under the supervision of an adult.
Building and operating these models requires technical expertise, manu-
al skills, a careful attitude and safety-conscious behaviour.
Errors, negligence and omissions in building or flying these models can
result in serious personal injury and damage to property.
Since the manufacturer and vendor are not in a position to check that
your models are built and operated correctly, all we can do is bring these
hazards expressly to your attention. We deny all further liability.
Aircraft propellers, and all moving parts generally, consti-
tute a constant injury hazard.
It is essential to avoid touching such parts.
Please bear in mind that motors and speed controllers may
become hot when operating.
It is essential to avoid touching such parts.
Do not stand close to the hazard area around rotating parts when
an electric motor is connected to the flight battery.
You must also take care to keep all other objects away from mo-
ving or rotating parts.
Observe the instructions provided by the battery manufacturer.
Overcharged or incorrectly charged batteries may explode. Take
care to maintain correct polarity.
Notes on the use of dry cells:
Do not attempt to recharge dry cells, do not open them, and do
not incinerate them. Remove exhausted dry cells from the trans-
mitter after use. Escaped electrolyte may ruin the transmitter.
Ensure the equipment is protected from dust, dirt and moisture contamination.
Do not subject the system to excessive heat, cold or vibration.
Use the recommended charger only, and charge the batteries only for the
prescribed period.
Check your equipment for damage at regular intervals, and replace defective
components with genuine spare parts.
Do not re-use any devices which have been damaged in a crash or by water,
even when they have dried out again.
Either send the equipment to the robbe Service Department for checking, or
replace the parts in question.
Crash or water damage can result in concealed defects which may lead to
failure in subsequent use.

propriate slot in the underside of
the fuselage, forward of the battery
compartment (Fig. 4).
Fig. 4
Push the main undercarriage into
the appropriate slot in the under-
side of the fuselage, aft of the bat-
tery compartment (Fig. 5).
Fig. 5
Place the wing in the fuselage, and set it at right-angles to the
fuselage centreline. This is accomplished by sliding the wing
leading edge into the locating recess, and securing the wing
at the trailing edge with the retaining screw (Figs. 1 + 2).
Fig. 1 Fig. 2
Engage the propeller in the
driver disc on the motor shaft
(Fig.3).

Flight preparation
Open the transmitter battery compartment and insert the
four AA cells* (check for correct polarity).
Switch the transmitter on (Fig. 1). The battery status is
shown on the left of the screen. Move the throttle stick and
trim to the bottom position (towards you). Open the batte-
ry compartment in the fuselage, connect the fully charged
flight battery, and close the battery compartment again
(Figs. 2 - 4).
The transmitter and receiver are now ready for use. Re-
peat this procedure every time you wish to fly the model.
Note: the 2.4 GHz transmitter and receiver are supplied
already bound at the factory. It will only be necessary to
bind the system again after a repair, or if you replace a
component.
The correct pre-flight procedure.
Fig. 1 Fig. 2 Fig. 3
Fig. 4
Checking the working systems
Before the first flight it is important to set all the trims - ex-
cept for the throttle trim - to centre. The throttle stick must
be in the "fully back" position (towards you). If the propeller
turns, adjust the throttle trim until it comes to a halt.
The correct post-flight procedure.
Open the canopy and remove the flight battery. Close the
battery compartment again, and switch the transmitter off.
*Notes on the use of dry cells:
Do not attempt to recharge dry cells, do not open
them, and do not incinerate them. Remove exhau-
sted dry cells from the transmitter after use. Escaped
electrolyte may ruin the transmitter.
Preparations for the first flight:
Wait for a day with absolute flat calm
conditions.
Charge the flight battery before fly-
ing.

Once the model is properly trimmed, you can practise the
art of flying, and carry out manoeuvres such as circles,
squares, rectangles and figures-of-eight.
To avoid giving incorrect control commands, always stand
behind and to one side of the model.
You can fly a square pattern by alternating the direction
of flight: away from the pilot, to the pilot's right, and then
towards the pilot again.
Tip: when the model is flying with the nose pointing
towards you, the controls are reversed (apart from ele-
vator and throttle control).
Important Notes
Launching:
Hold the aeroplane in your hand, set the motor to full power, and
push the model forward smartly, directly into any wind. It is es-
sential to adjust the trims so that the aeroplane flies in a sta-
ble attitude, climbing smoothly. Use the controls gently at first to
learn how the model responds to flight commands.
Landing:
Slowly and steadily reduce the throttle setting until the model
descends and touches down. Never reduce the throttle setting
abruptly. After the landing disconnect the flight battery from the
receiver, and only then switch the transmitter off.
Caution:
Stopping (obstructing) the motor when it is turning can cause
serious damage to the mechanical system, and may even result
in a fire. If the propeller is forcibly stopped, immediately move the
throttle stick back to Idle!
Note re. the flight battery:
As soon as you notice a reduction in motor power, land immedi-
ately and disconnect the battery. Never continue flying until the
battery is flat, as this causes a deep-discharge condition which
results in permanent damage. Allow the battery to cool down be-
fore recharging it.
Replacing the propeller:
A damaged propeller must be replaced immediately.

Re-binding the transmitter
This procedure is only necessary if you replace individual components, or if you wish to bind a FUTABA transmitter (please
also read the point "Binding the receiver" in the operating instructions supplied with your FUTABA transmitter).
1. Switch the transmitter on (Fig. 1) and connect the flight battery (Fig. 2). Ensure that the distance between the transmitter
and the model is not greater than 25 cm.
2. The green monitor LED on the receiver circuit board glows constantly. Locate the Bind button on the receiver (Fig. 3) and
hold it pressed in for about three seconds, then release the Bind button. The model is now bound. This procedure may
take several seconds. Do not move the model or the transmitter sticks during the binding process.
3. The green monitor LED continues to glow during the binding process. When the procedure is complete, the red monitor
LED on the receiver glows constantly. The model can now be operated.
