Safety notes

General

These safety instructions are intended not only to protect

the product, but also for your own and other people’s safe-

ty. Therefore please read this section very carefully before

using the product!

Do not leave the packaging material lying around, this could

be a dangerous toy for children.

Persons, including children, with reduced physical,

sensory or mental capabilities, or lack of experience or

knowledge, or not capable to use safely the receiver,

must not use it without supervision or instruction by a

responsible person.

The operation of radio controlled models must be

learned! If you have never driven such a model, then

start extra carefully and make sure to be familiar with the

reactions of the model to the remote control commands.

Proceed responsibly.

The insurance is mandatory for all kinds of model oper-

ation. If you already have one check out whether the

operation of the model is covered.

Always fly with a safe distance away from people and objects,

never fly low over people or directly towards them!

Never fly the model near power lines, industrial sites, resi-

dential areas, public roads, school yards or playgrounds

etc..

All model flyers must behave in such a way that public safety,

especially other people and property, as well as orderly flying

operations is not jeopardized or disrupted.

Inform passers-by and spectators before the start of the

dangers posed by your model and exhort them to keep a

safe distance.

Also observe the accompanying warnings of battery.

9944.RTF_jh_V1 7- 16

Controls before the start

Before each use, check proper function. For this purpose

switch on the transmitter and the receiving system. Check

that all controls are in neutral position, function properly and

turn down the correct side.

When flying a model aircraft for the first time, it is advanta-

geous if an experienced helper stands aside in the review

and the first flights.

Propellers powered by a motor represent a constant risk of

injury. Do not touch them with any part of the body! A rapidly

spinning propeller can e.g. cut a finger!

Keep well out of the rotational plane of the propeller! A part

of it or the entire propeller could broke and fly off at high

speed, hitting you or third parties. This can cause serious

injury. Make sure that no object gets in touch with a revolv-

ing propeller!

The blockage of the propeller, for any object must be

excluded.

Check each time before the model itself and everything

attached to it (e.g. propeller, tailplane etc.) is in good condi-

tion and undamaged. The model may be taken in operation

only after removal of all defects.

Radio interference caused by unknown sources can occur

without warning! The model is then uncontrollable and com-

pletely unpredictable! Do not leave the radio control system

unattended, to prevent operation by third parties.

Electric motor should be activated only if there is nothing in

the rotational plane of the propeller. Do not attempt to stop

the spinning propeller. Power the electric motors only with

the propeller installed.

The attitude of the model must always be clearly visible

throughout the flight, to ensure always a safely use and avoid

problems. Familiarize yourself during the flight, if any mal-

function / interference becomes noticeable, the landing must

be initiated immediately for safety reasons. You always give

way to other aircraft. Start and landing strips should be kept

free of people and other obstacles.

The model assembly

The model is ready to fly after a few adhesive or assembly steps,

the following instructions should be observed carefully so that

safe operation is ensured.

Fixing the rudder (2) to the fuselage (1)

For this purpose on both sides thin the enclosed contact adhe-

sive to the bonding surfaces, let the glue dry for about 1 minute,

then put off the rudder (2) and press firmly.

Inserting the landing gear (3) in the fuselage (1)

9944.RTF_jh_V1 9- 16

Installing the LiPo battery

First open the canopy. Hold the side to open at the front and pull

upwards

The figure shows the already installed LiPo battery.

CAUTION Risk of injury by rotating propellers, motors can start uncontrol-

lably when the XT-60 connector of the battery is connected.

Always mount propellers only after a complete general check.

The X 44 FLIGHT CONTROL

FLIGHT CONTROL X44 connection cables (left). The optional receiver will be

placed near it (right). The outputs have to be connected in the following

order:

1. Aileron

2. Elevator

3. Motor speed control

4. Rudder Note: the function is obtained by the motor speed

control

5. Control of the motor gondolas and flight mode, heli and aero

9944.RTF_jh_V1

10 - 16

The Flight Control is a highly complex electronic unit, that aero-

dynamically stabilizes the model over several gyros. Both aileron

/ elevator of the rear wing and the speed control of each brush-

less motor are controlled by this unit.

NOTE

Note that the model has to be hold after connecting the XT-60

connector in a stable position on a flat surface until the gyros of

Flight Control have initialized. This process takes a few seconds

and is confirmed by several beeps of the motors. The motor

gondolas run first on a 45 ° position. Only after this operation,

the Flight Control is functionally ready.

Note that the two rear motor gondolas are inclined in the vertical

neutral position approximately 2 ° forward, this is not a defect

but for optimal flight characteristics it is so required.

Also note that all rudder deflections are factory set correctly and

the control surfaces move when LiPo battery is connected, if

you tilt or rotate the model.

Installing the propellers

CAUTION Risk of injury by rotating propellers when starting the motors.

Always unplug the XT-60 connector to the LiPo battery before

working on the propellers.
