Dear Modeller,
Our name stands for first class scale models, designed to give endless pleasure. The average
modeller will be able to build and fly them without difficulty.

1970 The Practical Scale Company was started in England.

1974 Moved to West Germany.

1976 Obtained the exclusive import rights for the Quadra motor in Germany, this was the
beginning of the large models era.

1980 Gerhard Reinsch became my partner. Gerhard had just obtained his degree as an
Aircraft Designer, he has been consumed with the desire to build model aircraft for as
long as he can remember

1984 We imported the first Titan ZG 38, and this motor was a winner from the start.

1992 Moved to our new factory.

We are a direct marketing company, this is the reason we can offer the finest quality
products at very competitive prices.

What is it that makes our Kits so good?

● Ribs, formers and other

shaped parts are either
CNC milled with a high
frequency spindle run-
ning at 60,000 rpm or
profile belt sanded to
shape. There is no rag-
ged die stamping with
our kits, or the charred
edges from a laser cut-
ter.

● We carefully select all

Balsa and timber at the
log and finished stage. CAP 21 kit
Paired parts are matched for weight and hardness.

● Before we commence production the prototype is exhaustively tested.

● Our kits are really complete, spinners, tanks wheels, control linkages and so on, you
need only glue and covering material.

● We use not only standard self tapping screws but expensive Allen machine screws
with safety nuts where appropriate.

● You can of course ring us when you come up against a problem which is causing you
difficulty.

They were not intended to prevent spinning, but to
increase the rate of spinning, thereby speeding up
recovery. The effect was pretty doubtful which often
led to these strakes being removed later. It is for
this reason, that we do not supply these epoxy anti
spin strakes in the kit, so if the full size Tiger of your
choice is fitted with these, you have to order them
as an extra. By the way we have not been able to
notice any difference caused by these strakes when
fitted to our model.

 The Quality Control with our
Titan ZG - Engines
Zenoah engines are primarily industrial
units put together in flowband work. This
means a very solid construction with very
high quality of individual components.
This is the basis which we use for our ZG
engines. It is obvious by industrial mass
production that everything possible is
done to keep down the often biggest cost
component being wages.

According to Komatsu’s information, these

engines are assembled in 20 second tact
in sub assemblies. Time for completion
of one engine is two minutes, of course
in such a tempo there is no time for fault
finding not to mention correcting.

We were aware of this problem as long

ago as when we handled Quadras. It was Holger Stasing is just putting together a Titan ZG 80B

5 Years Guarantee
for our
Titan ZG - Engines!
Over 20 years experience with the Titan engines and our careful quality control allows
us to extend the previous one year guarantee period to five years. This guarantee covers
the engine and ignition components in addition to any legally required guarantee.

The following conditions apply:

The Guarantee is for 5 years from date of puchase.
The guarantee is only valid for the first purchaser, this guarantee is not transferable.
The serial number on the engine must not be damaged, defaced or removed. The pur-
chase date and the engines serial number is registered by us.
These engines must run only with the recommended two stroke petrol oil mixture. The
use of Methanol fuels nullifies the guarantee.
These engines may only be used with the original ignition. The fitting of the Easy Start
is of course allowed.
The guarantee includes the Microprocessor Ignition units, the maximum permissible
voltage must not be exceeded. Mechanical damage to the cables is not covered by the
guarantee.
The guarantee is that we replace any defective parts free of all labour and material costs
and pay only the return postage and packing. This guarantee covers only the engine and
can in no way be construed to cover anything else.
The guarantee can in no way be construed to cover crash damage or any following af-
fects of a crash.
This five year guarantee does not cover the G230RC and G260RC Car engine, the
ZG 23SLM and ZG 26SCM Marine engines and the ZG 23SLH, ZG 231SLH and
ZG 26SLH Helicopter engines.

carburettor to this bend, the fuel nipple on the ZG 23SL
must be turned in the carburettor body. This nipple consists
of a brass core with a riffled edge over which a plastic spout
is injection moulded. If you try to turn this nipple with pli-

the nipple useless as it will only leak. To avoid any trouble

the Vee belt in 1917.
The life of these Polyflex belts is unusually long,
we have had in our Tiger Moth a 2,8:1 gear that has
been flown regularly most weekends during the sum-
mer and it was six months before the belts needed
replacing. We often hear from our customers who
have been flying for several years with the original set
of belts. Because we fit two belts it is highly unlikely
that the belts fail simultaneously. When a belt fails
one can carry on flying without noticing anything until
the next start. With only one belt it is nigh impossible
due to slippage to start the engine, but a pair of new
belts are easy and quick to refit.

This silencer is constructed for the ZG 62 in combination
with the Hydro-Mount-System Pitts. The layout, where Kit #6659 Ready made #6650
the silencer is a counter balance to the cylinder, results
in a very effective functioning Hydro-Mount-System. The #6651

silencer fits perfectly under the Pitts engine cowl. Refer to #6656
the half-scale drawing of the HMS-Pitts on page 76. The #6653
spark plug is just about on the level of the crankshaft on the #6657
widest part of the cowl. Due to the built-in side thrust a little
extra space is obtained. This layout is ideal for the majority
of large models with horizontally opposed cylinders. There #6508

Stainless Steel Silencer with tuned header lenght
Tuned pipes are usually rather long and often difficult to
build into the fuselage. The silencer #5770 is only half
as long including the header, and lighter also.
Originally developed for the DA-50R, this tuned silencer
increases the power of the ZG 62 by 25%. The 23x12"
and the 24x10" Super Silence CF-propellers turn at
6,800 rpm. The silencer is neatly laser welded and
highly polished.
The optimum header length is 22 cm. It is measured
from the exhaust gasket along the cetre line of the
header up to the join between the header and the inlet
of the silencer.

Flat version carb bend for the ZG 62

Suitable for the Piper-

System and of course
for rigid mounted en-
gines. This manifold
is somewhat flatter in
profile than the manifold
constructed from two
flanges and a copper elbow. The intake tract of this manifold
is rather like a corkscrew and therefor allows a surprisingly
large radius. Running characteristics of the motor and power
output are excellent. All fixing screws are easily accessible.
You now have no reason for the unsightly carb to be poking
out of the cowl. This bend is supplied with fixing screws. For
use with the Piper and Pitts HMS we recommend you use
the 7 mm insulator #6567; alternatively the black standard
insulator supplied with the ZG 62 can be shortened to 7
mm. With the standard motor mount the 2 mm insulator
#6552 is preferred. One extra gasket #6504 is required!

for our
DA - engines!
This guarantee covers the engine and ignition components in addition to any legally required
Guarantee.

The following conditions apply:

The Guarantee is for 2 years from date of puchase.
The serial number on the engine must not be damaged, defaced or removed. The pur-
chase date and the engines serial number is registered by us.
The aluminium cylinder fixing screws must not be tightened or the engines taken apart
by the customers. The aluminium cylinder fixing screws can fail when the engine is run-
ning if they have been removed and refitted, or when they have been overtightened by
unskilled hands.
These engines must run only with the recommended two stroke petrol oil mixture. The
use of Methanol fuels nullifies the guarantee.

These engines may only be used with the original ignition.

The guarantee includes the ignition units, the maximum permissible voltage (6 V) must
not be exceeded at any time and the polarity must not be reveresed. Mechanical dam-
age to the cables is not covered by the guarantee.

The guarantee is that we replace any defective parts free of all labour and material costs
and pay only the return postage and packing. This guarantee covers only the engine and
can in no way be construed to cover anything else.

The guarantee can in no way be construed to cover crash damage or any following af-
fects of a crash.

 FEMA On Board Starter
With a FEMA electric on board starter you can start the engine from the trans-
mitter either on the ground or in the air. There are two types:

1. Universal on board starter:

With this version, the starter mechanics are fixed directly onto the engine. The
electric starter motor is mounted in the fuselage according to CG requirements,
or available space. The electric starter motor is coupled to the mechanics with
a Carden Shaft. There is a reduction gear wheel mounted onto the crankshaft
with a precision freewheel bearing.
As soon as the engine is running the freewheel bearing uncouples the gear
Universal wheel from the crankshaft. The electric starter motor is a high performance mo-
on board starter #9524 tor with gearbox. The Carden shaft can be shortened as required. This makes
(picture is without the kickback absorber)
for ease of installing the starter motor.

Advantages with the universal on board starter:

• Will fit into tight spaces.
• The adjustable Carden Shaft is fitted with a universal joint, allowing space
saving mounting of the starter motor in the fuselage.
• A recoil shock absorber can be fitted to the Carden Shaft.
• Simple to remove the engine due to the universal joint being able to be slid
apart.
• The engine can be fitted onto flexible rubber mountings as the universal
coupling can slide apart up to 3 mm.
Spacers #9581 (extra).
2. Compact on board starter:
The electric motor and starter are built directly onto the engine as a single unit,
thereby making a very compact unit.
Advantages with the compact on board starter:
• Simple to instal the engine complete with starter in the model as well as on
the test stand.
• Easy to maintain either the starter or the engine.
• The complete unit can easily be fitted to shock damped rubber mountings.
The on board starter kits contain all the necessary mechanical and electrical

engine can supply a special drilled spider leg motor mount.
The much feared kick back from the ZG engines, caused when not enough
fuel has been sucked in before starting, can be absorbed by the EKA-module.
(EKA = Electronic Kickback Absorber). This module contains a simple electronic
which feeds the primary current into the coil only after a certain higher speed has
been reached. This unit requires no extra energy supply and reduces the strain
on the gearing when starting the engine. The EKA-module
is inserted between the power coil and the ignition coil in the
existing double end connector.
With the ZG 80 twin the best answer is to convert the engine
to the PCI battery ignition, no need for the EKA-module then.
The starter is switched on with a servo operated Micro Switch.
A simple but more reliable method than with a complete elec-
tronic switching module.

The Starters (the complete sets as well) are supplied
without a battery. The Starters require high performance
NiCd-, NiMH- or LiPo batteries such as used for electric-
flight. For engines up to the ZG 38 9,6V is needed, for the
ZG 45 and 62 it is 12V. For the ZG 80 12V is minimum,
14,4 is better. Minimum capacity is 1,000mAh in every
case. Starting current is 16A.

 Redundant Signal Transmission over two frequencies in 35 MHz Band
ACT Safety for RC Models

Large models, either jets or piston engined, are poten-

tially dangerous as well as being very costly. The radio
transmission environment is rapidly changing causing a
distinct disadvantage in terms of safety, so much so that
new ways must be thought out to make the transmission
of signals to the receiver much more reliable.
The most reception problems occur with large and com-
plex models not at extreme range, but in normal range.
Many model pilots can tell about crashing after a fail-safe,
fairly close in to the transmitter, although the radio gear
has been functioning perfectly for a long while. The cause
is often the changes occurring in the radio environment

What is diversity reception?

DSL-System Scheme
Diversity-Synchro-Link Two receivers that are coupled with a data cable simultaneously re-
ceive the transmitter signal. They maintain the radio link even when
Channel 65 Channel 65 frequency-specific interference, spatial interference or interruption oc-
curs, because the two aerials are spatially separated (aerial diversity).
In both receivers the RF signal is analysed and demodulated resulting
in two LF signals of optimum quality. These signals are passed to the
Diversity processors fitted to both receivers. The processors communi-
cate with each other and decide which one of the two signals is better;
DSL-Synchro-Link-Cable the better signal is then passed to the servo output on both receivers.
This means that the signal from the “better receiver” is always shared
Channel 65 and is fed to each individual servo output on both receivers.
Due to the use of two separate receivers it is also possible to use
two frequencies (with the Simultaneous Dual-Frequency Tx module).

Infrared Interface (Irda) for the DSL-Receivers ACT Safety for RC Models

With this Irda, all DSL-receivers can be programmed wire-

less. This interface is compatible with Palm M100-M130,
Palm Zire 21 to Palm Zire 71, Palm Tungsten T3 and Tx and
several Handspring PDA’s, also with a Mobile phone that
has Palm compatibility plus a infrared interface such as the
Palm Treo 650, 680 and the Hagenuk S200.
The DSL infrared interface replaces the DSL cable (data
transfer cable between receivers) and can remain in the
Weight incl. Cables: 18 g model. Of course a single receiver can be coupled to the
Irda.
The interface has two yellow LEDs on the front side and in
the middle two transmitter/receiver diodes. These must be
visible to the Palm’s infrared interface to allow information
transfer. Each yellow LED is coupled directly with one of the
two cables and is then operative for the respective receiver
to which the cable is plugged into.
The Interface can be installed in the cockpit so that the front
side is visible. This allows you to read off the flight data
through the windscreen, and can be programmed without
a cable or opening a hatch. The reception performance of
each receiver as well as any interference can be shown.
The plugs and sockets, in spite of their small size are ex-
tremely robust and made to the highest industrial standards.
Futaba uses these plugs and sockets in the most vital
places in their transmitters. The insulation is reinforced
with synthetic fibers and is firmly crimped into the plugs and

the forward facing servo output plug pins and the flat laying
crystal makes the DSL-4ST ideal for fuselages with a very

All ACT miniature receivers are high quality, with very long
range and good channel separation. Therefore these receivers
are perfect for small electric models and gliders, but they also
have been developed specially with the indoor electric models
in mind. They counter very well the indoor reflection problem.

sary with the Fuzzy pro SMM V2. Trim out in normal mode,
switch into heading mode - finished.

I fly my clipped wing Taylorcraft with

two Fuzzy Pro SMM, one on the
ailerons and one on rudder. With fast
servos, the aerobatic characteristics
are considerably improved by the
gyros. This you must try out yourself to
experience the enormous difference in
flight performance!

 Heat shrink tubing
We use this heat shrink tube in the production of our Easy-Start unit. It
is high quality Polyolefin heat shrink tubing made to the military speci-
fication MIL-I-23053/5 class 3*. Shrinkage ratio is 3:1 and is therefore
suitable for many purposes. It remains flexible and shrinks at 100 oC.
It is ideal for insulating the relatively delicate servo cables.

Heat Shrink Tubing Usage:

The main use of this tubing in model aircraft

is of course for wiring up the radio equipment.
For lengthening the servo cables one takes the
3 mm tube #0023 and secures the joint addi-
tionally with the transparent tube #0016. This
allows one to control the safety of the joints.

For the green Multiplex high amperage plugs and

sockets, I use the heat shrink tube #0039 with hot
melt adhesive to secure the wires to the pins. I push
the heat shrink tube, while still hot, against the plug
and socket. The result is a very robust connection
that allows one to better grip the plug and socket.
The top quality high amperage Multiplex plug
and socket secured with heat shrink tubing.
