The Taurus 50 model helicopter you have purchased is a
member of the robbe-Schlueter family of helicopter products.
The model is designed as a helicopter trainer, and can be
assembled ready to fly in just a few hours.
The tools and accessories required to complete the model are
listed on a separate accessory sheet.
Notes on the radio control system:
All the pushrod lengths and servo output arm lengths assume
the use of robbe/Futaba servos.
If you wish to use other makes of servo you may need to make
allowance by adjusting the stated dimensions slightly.

Notes on the building instructions
The building instructions are grouped according to the
helicopter’s sub-assemblies.
Please follow the instructions in this section when assembling
your Taurus 50.
An assembly drawing is included for each stage, showing how
the parts fit together.
The drawings corresponding to the numbered stages of
construction can be found in the German instructions.
Each drawing also includes a full-size key to the screws,
ballraces, washers and shim washers required for that stage,
to help you identify these parts.
The stated dimensions are based on the standardised DIN
methods, e.g.:
Cheesehead screws:
M3 x 40 = diameter x length to end of screw, excluding screw
head.
Countersunk screws:
M3 x 20 = diameter x length to end of screw, excluding screw
head.
Grubscrews:
M3 x 3 = diameter x overall length.
Washers:
3.2 x 9 x 0.8 = internal diameter (I.D.) x outside diameter (O.D.)
x thickness.
Nuts:
M3 self-locking = self-locking nut with metric internal thread.
Each stage includes supplementary notes and tips which
should be read carefully while you are assembling the model.
You will also find information which will be helpful when you
are operating the model.
Basic information on construction, notes on replacement
parts
This model is designed for a right-hand rotation main rotor.
‘Right-hand rotation’ means that the main rotor spins
clockwise when viewed from above.
It is vitally important that you use only genuine replacement
parts when required. The Order Numbers are printed adjacent
to each component illustrated in these building instructions.
Please state the original Order No. when specifying
replacement parts, as this avoids problems and delays in
obtaining spares. Add the prefix ‘S’ to the Order No.
Example:
Replacement part required:
Main rotor shaft
Order No. SFH0003
Please store these building instructions in a safe place so that
you can refer to them later when maintaining or repairing your
model. The red Quality Control sheet and any other
supplementary sheets in the kit should also be kept safely.
How a model helicopter works:
A powered aircraft with a fixed wing and tail requires the thrust
of the propeller to get it flying. The forward motion of the wing
through the air produces lift; the model leaves the ground and
flies.
In contrast, a helicopter requires no forward motion. The wing
takes the form of an oversized propeller which rotates in the
horizontal plane above the fuselage. That is why helicopters
are also known as rotary-wing aircraft.
