Operating instructions - SKY SURFER RTF FTR 2.4 GHz No. NE2000FTR
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, which means that they can also be control-
led using 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
the point "Binding the receiver" in the operating instructions supplied with your FUTABA transmitter.

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

Operating instructions - SKY SURFER RTF FTR 2.4 GHz No. NE2000FTR

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 manufac-
turer.
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 conta-
mination. 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 de-
fective 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 stand with the long side of the aerial angled towards the model.
Insurance
Ground-based models are usually covered by standard personal third-
party insurance policies. In order to fly model aircraft you will need to
extend the cover of your existing policy, or take out specific insurance.
Check your insurance policy and take out new cover where neces-
sary.
Liability Exclusion
robbe Modellsport is unable to ensure that you observe the assembly and
operating instructions, or the conditions and methods used for installing,
operating and maintaining the model components.

The correct pre-flight procedure.
Preparations for the first flight:
Check that the Centre of Gravity is correct before flying the
model: it should be 25 ±2 mm aft of the wing root leading
edge (see diagram).
Wait for a day with absolute flat calm conditions.
Charge the flight battery before flying.
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. Replace
the canopy on the model, then switch the transmitter off.
Operating instructions - SKY SURFER RTF FTR 2.4 GHz No. NE2000FTR
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 right of the screen. Move the throttle stick
and trim to the bottom position (towards you). Open the
canopy, and connect the fully charged LiPo flight battery.
Ensure that the leads are firmly secured in the fuselage
(Figs. 2 - 3).
Replace the canopy on the model.
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.

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 essenti-
al to adjust the trims so that the aeroplane flies in a stable 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 de-
scends and touches down. Never reduce the throttle setting abrupt-
ly. 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 se-
rious 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 immediately
and disconnect the battery. Never continue flying until the battery is
flat, as this causes a deep-discharge condition which results in per-
manent damage. Allow the battery to cool down before 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 LED on the receiver circuit board will glow constantly. Locate the Bind button on the receiver (Fig. 3) and hold
it pressed in for about three seconds. Release the Bind button again: the model is now bound to the transmitter. This
process may take several seconds. Do not move the model or the transmitter sticks during the binding procedure.
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.
