The model is designed for the components specified by us. Unless otherwise stated, servos and other electronic
components are designed for standard supply voltage. Recommended cell count for Lipo batteries also refers
to standard Lipos voltage of 3.7V per cell. If you use other servos, a different motor and controller, batteries, or
propellers, please make sure they fit first. In the event of deviations, corrections and adjustments must be made
by yourself.
•
Before starting construction, always put the servos into neutral. To do this, switch on the remote control and
move the joysticks and trim buttons (save the one for the throttle) to the middle position. Connect the servos to
the corresponding outputs of the receiver and supply them with a suitable power source. Please observe the
connection diagram and the operating instructions of the remote control system manufacturer.
•
Do not leave your model in the blazing sun or in your vehicle for long periods of time. Too high temperatures
can lead to deformation/distortion of plastic parts or blistering of covering foils.
•
Before the first flight, check the wing symmetry, tail unit and fuselage. All parts of the model should have the
same spacing from the left and right wing or tail plane to the centre of the fuselage or the same angle.
•
If necessary, rebalance the propellers if vibrations are noticeable when the motor is running up.
•
Bubble formation in the covering foils normal to a certain extent due to temperature and humidity differences
and can be easily eliminated with a foil iron or hairdryer.
•
For models in shell construction („full GFRP/CFRP“), burrs may occur at the seams due to the production pro
-
cess. Carefully remove them with fine sandpaper or a file.

•
Be sure to read the safety instructions carefully before operating your model.
•
Always follow the procedures and settings recommended in the instructions.
•
If you are using remote-controlled model aircraft, helicopters, cars or ships for the first time, we recommend that
you ask an experienced model pilot for help.
•
Remote-controlled models are not toys in the usual sense and may only be used and operated by young peo
-
ple under 14 years of age under the supervision of adults.
•
Their construction and operation requires technical understanding, careful craftsmanship and safety-conscious
behaviour.
•
Mistakes or negligence during construction, flying or driving can result in considerable damage to property or
personal injury.
•
Since the manufacturer and seller have no influence on the proper construction/assembly and operation of the
models, these risks are expressly pointed out and any liability is excluded.
•
Propellers on aircraft and all moving parts in general pose a constant risk of injury. Avoid touching such parts at
all costs.
• Note that motors and controllers can reach high temperatures during operation. Avoid touching such parts at
all costs.
•
Never stay in the danger area of rotating parts with electric motors with connected drive battery.
•
Overcharging or incorrect charging can cause the batteries to explode. Make sure the polarity is correct.
•
Protect your equipment and Models from dust, dirt and moisture. Do not expose the equipment to excessive
heat, cold or vibration.
•
Use only recommended chargers and charge your batteries only up to the specified charging time. Always
check your equipment for damage and replace defects with original spare parts.
•
Do not use equipment that has been damaged or got wet due to a fall, even if it is dry again! Either have it
checked by your specialist dealer or in the Robbe Service or have it replaced. Hidden faults can occur due to
wetness or a crash, which lead to a functional failure after a short operating time.
•
Only the components and accessories recommended by us may be used.
•
Do not make any changes to the remote control which are not described in these instructions.

Attention, danger of injury!
•
Always keep a safe distance from your model aircraft.
•
Never fly over spectators, other pilots or yourself.
•
Always perform flight figures in a direction away from the pilot or spectators.
• Never endanger people or animals.
•
Never fly near power lines or residential areas.
•
Do not operate your model near locks or public shipping.
•
Do not operate your model on public roads, motorways, paths and squares, etc., but only in approved loca
-
tions.
• Do not operate the model in thunderstorms.
•
Before each flight, check your remote control system for sufficient function and range.
•
After flying, remove all batteries from the model.
Do not „aim“ the transmitter antenna at the model during operation. In this direction, the transmitter has the lowe-
st radiation. The best position of the antenna is to the side of the model.
Use of devices with image and/or sound recording function:
If you equip your model with a video or image recording device (e.g. FPV cameras, action scams etc.) or the mo
-
del is already equipped with such a device at the factory, please note that you could violate the privacy of one
or more persons by using the recording function. An overflight or driving on private ground without the appropriate
permission of the owner or approaching private ground can also be regarded as an invasion of privacy. You, as
the operator of the model, are solely and fully responsible for your actions.
In particular, all applicable legal requirements must be observed, which can be found in the roof associations or
the relevant authorities. Failure to comply can result in substantial penalties.

Congratulations on your purchase of the new SAPPHIRE!
The SAPPHIRE is a high-quality allround glider with a dynamic flight envelope.
It can be flown within in a broad speed range. There are various ways of constructing the model, depending on
your preferences.
Therefore the solutions stated in this manual should only be considered as recommendations.
For the most parts, the PNP (plug and play) version is already prefabricated.
The ARF version (almost ready to fly) requires modeling experience and basic technical knowledge in construction.
Thus there are different ways to achieve a model with good flight skills.
This is why most alternatives are in fact explained in the manual but not necessary shown in the pictures.
PLEASE READ THIS MANUAL CAREFULLY BEFORE YOU START ASSEMBLING THE MODEL.
F L I G H T I N S T R U C T I O N S
•
Before the first flight, observe the instructions in the „Safety Instructions“ section.
•
When flying the model, you should choose a day with as little wind as possible
•
A large, flat area without obstacles (trees, fences power lines etc.) is suitable for the first flights.
•
Please carry out a functional test of the drive train / power set and remote control.
•
After assembling the model on the airfield, check once again that all model components such as wing, tail
units, wing mounts, engine, linkages, etc. are firmly and properly fastened.
• For a hand start a helper should be present, who can throw the model with enough thrust into the air.
•
The start usually takes place against the wind.
• Do not stall the model near the ground
•
Do not initiate tight turns in the immediate vicinity of the ground.
•
Check the reactions of the model to the rudder deflections. If necessary, adjust after landing to increase or
decrease the deflections accordingly.
•
The minimum flight speed must be at an adequate safety altitude.
•
Initiate the landing with sufficient speed
