Dear readers!
Ernst Ramberger
Director
Step-Four GmbH
Spring awakening
Just as nature will soon be in full bloom,
we also want to break some ground and
rise to the coming challenges with renewed
zest and lots of energy, after a pretty
turbulent year. In times such as these,
not only is it particularly important to manufacture
products of the highest quality,
but also to provide additional benefits. Although
we have cultivated close customer
relationships and followed a customer-oriented
policy for many years, for 2010
we intend to concentrate even more on the
areas of customer care, service and support.
Because satisfied customers are and
will always be the foundation of a prospering
company.
We find solutions
Focussing on customer requirements
has to begin even before machines are
installed. With regard to this, we are
able to provide our customer with solution
proposals, even for the most tricky
or cramped space conditions. More information
can be gathered from the inside
pages. I am particularly pleased about the
delivery of the hitherto largest Step-Four
system, an Xpert CUT 5000 with a cutting
length of up to 8 metres!
New look
Here it is! The new Step-Four Magazine.
After long and numerous brainstorming
sessions, reams of ideas and a variety of
layouts, we are very happy with the result.
We not only revised the look of the new
Step-Four Magazine, but we also decided
to revise the content and perform a “relaunch”.
After ten successful years of publishing
our customer newsletter, you now
hold a magazine in your hands that is more
comprehensive than ever before. We hope
that you like the new magazine. We would
be pleased to receive your feedback.
Shape the future with us
Another inspiring suggestion! Due to the
fact that we have enjoyed a pleasurable
and successful collaboration with our customers
over the many years, we would like
to invite you to take part in launching new
projects. Shape the future with us by informing
us about your requirements and
ideas. Perhaps this will lead to a joint
project.
Yours sincerely, Ernst Ramberger

Face-lift for the
PC-CUT Standard
After many years of success, the tried and
tested PC-CUT Standard hot wire cutting
system has now been given an advantageous
face-lift. The ingenious yet simple
construction itself didn’t actually need to
be modified, but the spindles and shafts
were given larger dimensions, which will
provide higher speeds with the lowest level
of vibration.
With immediate effect, 16 mm steel shafts
and spindles with an increase of 3 mm are
applied. The spindle motor couplings are
made of aluminium from now on. Thanks
to the application of cable carriers, cable
spaghetti is also a thing of the past. Even
though we have performed these improvements,
the prices remain unchanged.
Railway
histories
On the occasion of the 25th year jubilee
celebrations of the Model Railway Club in
Eferding, Mr. Loidl, a faithful Step-Four
customer from Fraham in Upper Austria,
proudly presented the model of the first
locomotive of the Linz local railway, the
E22 002, model 1912. This particular locomotive
travelled along the Linz – Eferding
– Weizenkirchen line at that time. The
construction and completion time for the
model amounted to 200 hours.
New: Safe-Coat in
500 g containers
SAFE-COAT, the coating for EPS, XPS,
wood, plastic, and lots more, is now also
available in 500 g containers, as well as
the hitherto available 5 kg containers. The
sales price lies at € 12.60 incl. VAT. The
base colour of the coating is transparent
and can be coloured according to choice
by simply adding pigments. The material
is applied by means of a brush or roller.
Drying is performed without shrinking effects.
The surface is smooth and even and
can be painted. The Safe-Coat coating can
be used as a base coating on EPS and XPS,
so that a more “aggressive” coating (solvent-containing
paint) can be subsequently
applied. SAFE-COAT can be used without
the necessity of breathing protection.
Xpert Cut: Think
big, cut bigger!
At the end of February, we were able to
deliver the hitherto biggest system of the
new Xpert CUT series. With an operational
range of 5000 x 2600 x 8000 mm, enormous
parts, which previously had to be
manufactured in painstaking detail work
with several individual elements, can now
be produced in one piece.

INTRODUCING
Ascending Technologies: The specialist for
multi-rotor aircraft systems
We take particular pleasure in observing
the success of young companies working
with Step-Four systems. The two Achtelik
brothers from Stockdorf near Munich acquired
their milling machine in 2002 – at
which time they were still students-. Innovative
ideas combined with diligence and
perseverance finally led to the founding of
a successful company.
Ascending Technologies – the name of
the company stands for innovative multi-rotor
aircraft systems. Many years of
experience, based on the award-winning
“Jugend forscht” (Young Scientists) work
performed by the managing partners and
employees, as well as a great enthusiasm
for flying systems, are a guarantee for sophisticated
and innovative concepts, which
have created one or another revolution on
the “quadrocopter skies”.
The high-tech devices have been used for
a number of special assignments, such as
the examination of large-area coal fires in
China, which was performed for research
A quadrocopter
from astec
institutes, to fly over archaeological excavation
sites in Mongolia, and to observe
whales in Argentina. Many photographers
use the robots for high-quality aerial photographs.
Are you looking for a robust, light and manoeuvrable
quadrocopter, with which you
can impress your friends by letting it hover
around your living room or soar across the
skies outdoors with a breathtaking aero-
batic programme? Or do you need a
means by which you can shoot aerial
photographs and videos? Do you perhaps
need a flying sensor carrier for
research projects? Then visit the website
www.asctec.de.
By the way: Both the prototypes and
the serial models are still being produced
today with the aid of Step-Four
products.

Training
HTBLA Ried in the Innkreis district
Practical training for budding engineers
On the 22 of January 2010, the brand new
HTBLA State Polytechnic Institute in Ried,
in the Innkreis district of the Upper Austrian
Innviertel, presented their “Open Day”.
The HTBLA Ried provides the students
with the best possible foundation training
for career entry of academic studies
through hands-on, practical training. This
is achieved by a collaboration between industry,
commerce, and school, which is
unique in Austria. A part of the training
takes place as workshop tuition directly
on the premises of the participating companies.
Construction lessons are also provided
directly in the companies or are “online
connected”.
Step-Four Head of Marketing Reinhard
Leithner was able to assure himself, during
his visit at the polytechnic, that the students
are not only in good hands under the
supervision of Head Instructor Franz Liebl.
The excellently equipped school provides
the young ladies (yes, there are a number
of enthusiastic female engineers) and gentlemen
with the best training for their futures.
The Step-Four milling machine is,
of course, an essential feature.
Step-Four is pleased to have experienced
a successful day at the school and wishes
the students and teachers all the best for
the future. Further details can be gathered
under www.htl-ried-innviertel.at.
A focus on manufacturing technology
Under consideration of economic thinking,
the field of manufacturing technology
imparts knowledge on the theoretical
and practical principles in
the field of mechanics, construction
of machines and systems, and manufacturing
technology, supplemented
by knowledge in electrical engineering,
measurement, control and regulation
technology, as well as operational
sequences with particular consideration
of quality management and product
management.
Learning is fun with the top equipment.

Service
How does the sailing ship get inside
the bottle?
You will perhaps ask yourself
what this age-old
question has to do with
Step-Four. Quite a lot. Due
to the needs and requirements
of our customers,
the Step-Four systems have
become increasingly
larger over the last few years.
The Xpert series is a
perfect example.
Just as with the demands that our company
has to meet, the machines get bigger
all the time. Unfortunately, however, the
doors of our customers‘ workshops don’t
grow at the same rate as the dimensions
that are required of the milling machines.
What’s the solution? Well, some providers
leave this problem to the customer. Step-
Four doesn’t.
A tight fit. The Step-Four system is bigger than the workshop door.
Installation without renovation
We not only build high quality systems, but
also ensure that they can be installed without
the need to perform extensive renovations.
If necessary, we will bring out own
marquee in order to protect the system
and our experienced assembly fitters from
the whims of weather during the on-site
unloading or assembly work. A high level
of flexibility regarding the installation of
machines is an integral part of our corporate
maxims of customer care, service and
support. We have meanwhile managed to
gather a lot of experience in installing the
large Xpert systems. Even customers with
very limited space conditions can safely
assume that we are able to find a solution
to (practically) every space problem.
Just ask us.
We’ll find a way.

Intermodellbau 2010 without Step-Four
For the first time in 15 years, we will not
participate as an exhibitor at this year’s
“Intermodellbau” in Dortmund. You probably
ask yourself: Why not?
Well, during the last few years we have
observed significant changes regarding
the number of visitors and thematic focus,
which, in our opinion, are anything
but positive. Therefore, we had to ask ourselves
whether or not a participation justifies
the enormous expenditure of time
and effort.
New role model
The “Intermodellbau” was once the leading
trade fair for model building in Germany,
but, in our opinion, this title has
increasingly moved to the model mak-
ing fairs “Faszination Modellbau” in Friedrichshafen
and Sinsheim. By the way, this
year’s “Spring - Faszination Modellbau”“
exhibition will take place for the first time
in Karlsruhe from the 25th till the 28th of
March. Many discussions were held within
our company and with fellow exhibitors,
customers and prospective customers.
The ultimate result was that we decided
not to participate at the “Intermodellbau”
2010. The future will show whether or not
the “Intermodellbau” will again become
what it once was. If so, then we‘ll be happy
to return.
In order to still be able to reach as many
customers and potential customers as
possible in Germany, we will participate
in numerous other events that focus on the
subject of model aircraft construction. We
are convinced that those events will bring
us closer to the real model makers. Furthermore,
it would be our pleasure to be
able to welcome you at our company base
in the beautiful district of Salzburg, where
we can give you a personal presentation of
our products. Come and visit us!
We would like to hear your opinion
I hope for your understanding regarding
our decision not to exhibit at the “Intermodellbau”
this year, and hope that this
causes you no inconvenience. We would
very much like to hear your opinion on this
matter. Simply write me an e-Mail to reinhard.leithner@step-four.at.

Rubrik
The “Fairey Rotodyne” is ready for its maiden flight.
An extraordinary scale model is created with
the “Basic 540”
Phillipp Gardemin from Baden-Württember,
Germany,
reports about building
this helicopter model with
the aid of a Step-Four Basic
540. With a rotor diameter
of almost three metres,
this is a mighty big chopper.
I dreamt for years about building a “Fairey
Rotodyne” scale model. I flew this extraordinary
helicopter in the late 50s, in England
– but unfortunately this project didn’t
get past the prototype status. This helicopter
was extraordinary due to the fact that
the almost 30 m main rotor was tip-driven.
The tips were powered by a mixture
of fuel and compressed air bled from two
wing-mounted turboprops.
The model was constructed at a scale of
1:10. In order to be able to bypass the mechanical
complexity of the tip drive, the
plan was to operate the model as an autogyro
aircraft. This means that the rotor
is driven by the airflow, thus, allowing the
model to take off. The first drawings were
created on the CAD. The dimensions were
then taken over from a plastic model by the
Airfix company.
Realisation with Step-Four
The fulfilment of the dream, however,
could only take form with the acquisition
of the “Basic 540” milling machine.
The general layout drawings in the CAD
gradually became a tangible plan. Thus,
the individual parts separately drawn, exported
to the milling software, and then
be directly milled. Only poplar plywood in
thicknesses of four and three millimetres
was used. The sheeting was made from
1,5 mm balsa.
Ten month construction period
During a construction period of over ten
months, the milling machine became a
best friend. Even the smallest of parts
were drawn, exported to the milling software,
and subsequently milled. The large
cockpit, for instance, was quasi drawn
from nothing in the CAD, the parts exported
and milled. After a total construction
period of twelve months, the model
stood on the meadow, ready for flight.
Two Hyperion external rotors with 4 blade
airscrews from Varioprop and a 6s LiPo
6500 mAh served for propulsion. The rotor
blades – consisting of a Styrofoam cores
with carbon reinforced plastic spars and
plywood sheeting – rotated in a four-blade
rotor hub from Varioprop and a self-built
swivel mechanism. The entire model now
weighed 10.5 kg.
Test flights
The “Fairey Rotodyne” was unfortunately
unable to perform its maiden flight, which
was due to the fact that the self-built autogyro
mechanism wasn’t powerful enough
for the enormous rotor diameter of almost
three metres. The model is currently undergoing
modifications, whereby mechanical
details are being improved upon, as
well as the mechanic of the swivelling vertical
tail fins. New test flights are planned
for spring 2010. The “Basic 540” will certainly
provide me with many more good
services until then.
Philipp Gardemin
10 STEP-FOUR | March 2010

Model making
The original „Fairey Rotodyne“ of the
50s unfortunately never quite past the
prototype status.
The frames and spar caps were milled
from 4 mm poplar plywood.
The rotor tower with the mounted mechanism.
The tail with the swivelling vertical tail
fins consist of a spar-ribbed construction
made from milled 3 mm poplar plywood
parts.
Thanks to CAD and CNC, retrospectively
constructed parts also fit perfectly,
such as the servo holder above.
Many parts of the cockpit construction
were designed as a basis on the CAD
and then milled.
The wings are also rib constructions
with standing crest spar.
The engine nacelles consist of inner
parts constructed and mounted as housings
– all drawn and milled, of course.
After a construction period of eight
months, the body shell was practically
complete.
The rotor mechanism unfortunately
proved to be insufficiently stable
enough for flight.

PRACTICE TIPS
Tips from our specialists
Our modelling expert
Hannes
Schmalzer advises:
Wing Designer: Show left wing and print
out!
In order to be able to show and print out the
wing in Wing Designer, proceed as follows.
• Move the cursor on to the intersection of
the two lines and click the right mouse
button.
• Select the line tab in the opened characteristics
window.
• Mark in the checkbox of the left pointing
X arrow.
• Confirm by pressing “accept” and the
left wing will be shown.
• The wing can also be mirrored in the Y
direction. Printing out is performed as
with the left wing.
S4CUT V4 cutting software:
In order to ensure that the cutting software
can be used with the second PC dongle
on a Windows XP computer, the CON-
FIG.NT has to be entered at the end of the
files=50 list.
DXF import:
The object dimensions are not correct after
importing from CorelDraw. Important!
CorelDraw draws metrically, but exports
imperially. The unit 1 :25.4 must be entered
in the import filter of the milling software.
TurboCAD:
Before exporting a drawing in the DXF
format, ungroup all items, also known as
exploding in TurboCAD. Text excepts and
written items also have to be exploded.
Thus, they can be exported in DXF format
and then be opened or imported in the
milling and cutting software.
Our design engineer
Roman Tutschka advises:
XpertMILL:
What a lot of people don’t know: When
moving the machine to set zero point or
tool change point via the keyboard, one
can move between XY and Z with the aid
of the space key.
Milling aluminium:
Type F2422 milling cutters are particularly
suitable for milling aluminium. Do not immerse
too slowly into the material, otherwise
a built-up edge can form, which leads
to premature wear of the milling cutter.
And don’t forget the cooling agents! Recommended
parameters:
• Milling cutter diameter: 2 mm
• Advance: 2 mm
• Speed: 24000 r/min
• Forward feed XY: 220 mm/min
• Forward feed Z: 200 mm/min
• Cooling: Atomised spray with n-paraffin
