Dear Robbe Modellsport Customer!
Thank you for purchasing our rc-plane „RASANT Speed".
The current model is a tribute to the legendary Robbe original of the early 70s and has been carefully modernized
so as not to lose the charm and character of the model, but still meet the increased demands of modern times. As
in those days, the new edition is available in two versions. On the one hand in the classic drive version for glow igni-
tion engines with approx. 3.5ccm, on the other hand for electric drive, but in a more modern design as 1977 for the
current, more powerful brushless drives in combination with Lipo battery. Especially the „Speed" version with the
outward tapered wing looks visually dynamic and underlines the claim of a speed model of its time. Taken from
the Robbe catalog 1977: „A model for advanced RC pilots who want to get involved in show flying or experience
the thrill of „speeding" for their own pleasure without spending a lot of money.
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

• 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.
