Introduction
The Spirit M-8 model helicopter you have purchased is a
member of the robbe-Schlueter family of helicopter produc-
ts.
The model is designed as a helicopter trainer, and can be
assembled ready to fly in just a few hours.
Please follow the instructions in this section when assemb-
ling your Spirit M-8.
The drawings corresponding to the numbered stages of con-
struction can be found in the German instructions.
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 assu-
me the use of robbe/Futaba servos. If you wish to use other
makes of servo you may need to make allowance by adju-
sting the stated dimensions slightly.
The building instructions are grouped according to the heli-
copter's sub-assemblies, and are divided up in a logical
sequence of stages. Each sub-assembly is numbered, and
the numbers correspond to the numbered bags in the kit.
An assembly drawing is included for each stage, showing
how the parts fit together.
Each drawing also includes a full-size key to the screws,
washers and shim washers required for that stage, to help
you identify these parts.
Each stage includes supplementary notes and tips which
should be read carefully while you are assembling the model.
Replacement parts
approx. 818 mm
It is vitally important that you use only genuine replacement
approx. 178 mm
parts when required. The Order Numbers are printed adja-
approx. 710 mm
cent to each component illustrated in these building instruc-
approx. 260 mm
tions.
min. 1300 g
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.
Please state the original Order No. when ordering replace-
ment parts, as this avoids problems and delays in obtaining
spares.
If you think you have cause for complaint, or wish to make a
claim under guarantee, please note that you must state the
Control Number and include proof of purchase.
Replacement screws
The kit includes a pack of spare screws which can be used
to replace lost or damaged items during the lifetime of the
model.
The electric motor
The electric motor must be run-in before the model is flown.
The running-in process "beds in" the carbon brushes so that
they make proper contact with the commutator.
Please see the notes on page 8.
Notes on construction:
You will find three different symbols throughout these
instructions:
1: Oil can
- At these points you must apply synthetic oil (robbe No.
5531) during assembly.
2: Grease dispenser
- At these points you must apply grease (robbe No. 5532)
during assembly.

3: Loctite
- At these points you must apply thread-lock fluid (robbe
No. 5074) during assembly.
L
Remove all traces of grease from the threaded holes and
screws before applying thread-lock fluid.
Tip: Loctite should always be applied very sparingly, other-
wise there is a danger that excess fluid will run into ballraces
and plain bearings. A good ploy is to apply the fluid to the
female threads (holes).
Note: Oil the pushrods lightly
before screwing the ball-links
onto them. We recommend the
use of the ball driver, No. S 5151,
for this.
When pressing ball-links onto lin-
kage balls and ball-end bolts note
the position of the raised marker
lug on the link, which should
always be on the outside of the
joint.
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 heli-
copters are also known as rotary-wing aircraft.
Order No.
