Introduction
The „IQ-Hammer“ RC model jet engines by Hammer Engines have the same functional
principles as their big counterparts. A high performance compressor compresses the ingested
air, which is then heated by fuel flame in the combustion chamber and the heat causes the air
to expand rapidly, enabling it to drive an axial turbine rotor, which in return drives the
aforementioned compressor via a shaft. This is called a closed loop setup.
The hot air leaves the engine at the exhaust cone at a speed in excess of 1000 km/h (621 mph),
generating the necessary thrust for the jet aircraft model. An electric starter motor and a new
electric kerosene ignition system allow for a fully automated engine control setup using
nothing but your transmitter. The system is controlled and monitored by the IQ-ECU control
unit, which checks and controls all parameters for their optimal values. This new generation
of model jet engines no longer requires auxiliary gases such as propane or butane. The
system and all of its components such as the fuel pump, kerosene ignition, valve and so forth
are powered by a separate.
The IQ-Hammer jet engines share the basic outer dimensions with their predecessors yet offer
more power (90N-180N).
The latest in CNC- and laser cutting technology allow for unprecedented standards in
precision, material properties and mechanical characteristics, ensuring both the highest
performance as well as durability. The included display/ programming unit (EDT or Engine
Data Terminal) comes equipped with an illuminated LC-Display and can be connected to (and
disconnected from) the running system at any time of operation in order to check on the
current operating data readouts or in order to change parameters. Besides current and effective
operating parameters such as exhaust gas temperature (EGT), turbine revolutions per minute
(rpm) and thrust (throttle), additional information such as total hours of operation, rpm and
temperature statistics, number of engine starts, battery voltage and so forth can be read out
and displayed.
All parameters and inputs are displayed in plain text in the menu-based interface. The turbine
is being started fully automatically via the transmitter’s throttle stick. The pilot then adjusts
the desired thrust by moving the stick proportionally. The IQ-H control unit is connected to
the R/C receiver via the R/C-1 output.

Safety Precautions
Welcome to the Jet Age of RC model aircrafts!
Never forget: Operating a jet engine like the IQ-Hammer can be dangerous. An aircraft model
equipped with the IQ-Hammer can reach speeds of more than 400 km/h (250 mph) and
temperatures up to 500 °C (930 °F) at the engine housing and up to 750 °C (1380 °F) at the
exhaust jet. Since it is a genuine jet engine, it requires know-how, discipline and regular
service and maintenance – for your own protection and that of other people.
If other persons or animals are present while operating the IQ-Hammer turbine, ALWAYS
ENFORCE THE PROPER MINIMUM SAFE DISTANCES FROM THE TURBINE!
The recommended minimum safe distances are:
In front of the turbine = 3 feet
On the side of the turbine = 36 feet
Behind the turbine = 30 feet
Fire extinguishers should be on hand at all times. Hammer Engines recommends CO/2
(Carbon Dioxide) extinguishers of at least 5 pounds capacity. Powdered extinguishers will
contaminate the precision components, upsetting the integrity of the turbine. To the avoid
hearing damage, always use hearing protection when you are near a running turbine engine!
When the turbine is running, never place your hands closer than six inches into the area of the
intake. An extreme suction - which can grasp a hand, fingers or other objects in a flash prevails in this area. Be aware of this source of danger, always! Prevent foreign materials
from entering the intake or exhaust when working with the turbine. Before operation, make
sure there are no lose parts or debris near the turbine. Objects being sucked in can cause
severe damage.
If you want to install and operate this jet engine in your model aircraft, you must be trained in
its handling and very experienced in model airplane operation in general. The model with the
jet engine should only be operated under supervision of an experienced person who can
support you in order to avoid mistakes. If there is a local R/C club in your area offering
training and support, we recommend that you become a member. Mistakes made during the
assembly or operation of a jet-powered model aircraft can lead to serious injuries or even
death.
Always observe the law. Before operating a model aircraft with this jet engine, you should be
informed about the legal regulations regarding such aircraft. From a legal point of view, a
model aircraft is considered an aircraft like any other in most countries and is subject to the
corresponding laws, which must be observed by all means. Please check the applicable air
traffic laws of your country carefully before flying your model. Your local R/C club will
likely be able to provide you with the required information and documents. In many countries,
jet-powered model aircraft require a special license and/or a special insurance. Furthermore,
regulations regarding the protection against interference between R/C transmitters and radio
networks must be observed. Please make sure to comply with all applicable laws and
regulations in your country.
It is your responsibility to protect others against injuries. The operating distance of your
aircraft from residential areas must be at least 1.5 km (1 mile) in order to ensure the safety of
people, animals and buildings. Keep a safe distance from power lines. Never fly your model
5
in bad weather with low clouds or fog. Never fly directly against the sunlight – otherwise you
might lose visual contact with your model. To avoid collisions with manned or unmanned
aircraft, land your model immediately if an aircraft is approaching. Persons and animals must
keep the following minimum distance to the jet engine (see also the figure on page 6):
In front of the engine: 1 m (3 ft)
At the sides of the engine: 12 m (36 ft)
Behind the engine: 10 m (30 ft)
Assure that the fuel is mixed with approximately 5% Aeroshell 500 or Aeroshell 560.
Synthetic turbine oils are dangerous and should only be handled per the manufactures MDS
sheets.
Never run the turbine in a closed room, or an area near any kind of flammable matter. Do not
fly turbine-powered aircraft near flammable materials, nor in forested tracts or areas
experiencing drought or dryness. Obey all forest fire regulations and warnings by refraining
from operating the IQ-Hammer turbine jet aircraft in restricted fire zones.
Installation of unauthorized parts from another manufacturing source may also result in
engine failure. Do not introduce engine or electronic components other than those delivered
by Hammer Engines, unless you are willing to risk destroying your turbine! Hammer Engine’s
parts are designed and engineered specifically for the IQ-Hammer engines. Accept no
substitutes, unless you are prepared to sacrifice your aircraft.
Warning:
A flying model with a turbine can reach higher flight speeds than ducted fan-powered models,
because the turbine’s thrust degrades less with higher flight speeds. With attainable flight
speeds of over 250 MPH, you can quickly run out if flying room. There is also a danger of
developing control surface flutter or mechanical overload, causing the model to fail in flight.
When piloting a turbine powered aircraft, one must properly control the throttle. Full power
should be used for takeoff or vertical maneuvers and a reduced setting for level or descending
flight. To restrict the maximum flight speed, an optional airspeed sensor is available.
The jet engine may only be operated in exact compliance with the instructions found in this
manual. Furthermore, the specifications of the aircraft model regarding the centre of gravity
and rudder travel as well as all information in regards to construction and materials as well as
components used must be adhered to. Before flying a model jet aircraft equipped with the IQHammer turbine all functions and all rudders as well as the range of the R/C transmitter must
be tested with the transmitter turned on and the antenna retracted or set to “Range check”
output in case of a 2.4 GHz system. This range test must be repeated with the jet engine
running while another person is holding the model in place. Furthermore, the instructions by
the R/C system manufacturer must be followed closely.
Any deviation from the specifications in this manual, the use of non-approved parts or
materials or modifications to the system construction or setup can have a negative effect on
the functionality and safety of the jet engine and must be avoided by all means.
Warning:
It is strictly forbidden to operate the model and/or the jet engine under the influence of
alcohol, drugs etc. The jet engine may only be handled by persons in excellent physical and
mental condition and with utmost concentration. This applies to the operator as well as any
assistants. This jet engine was designed solely for use in model aircraft and is not suitable for
any other purpose. Never use it to transport persons, objects or vehicles other than a suitable
jet model airplane as any other forms of use can or will lead to personal injury or even death.
6
Hammer Engines GmbH / IQ-Series / Instruction Manual
Only test the jet engine at suitable places outdoor and observe the applicable laws
and regulations.
Always enforce the proper minimum safe distance from the turbine:
- Never look straight into the exhaust jet and never touch it or the exhaust stream with
your hands.
- Whenever possible, wear hearing protection.
- Keep away from the engine intake (electric starter). The air stream has an enormous
suction power, which can lead to severe injuries.
- After the first installation, and afterwards in regular intervals, test the transmission
range of your R/C system with the jet engine running. Before operating the engine,
remove all loose objects near the engine intake, such as cleaning cloths, screws, nuts,
cables or other material. Before operating your model for the first time, make sure that
there are no loose objects in the engine intake, such as clippings, screws or debris from
building the model. Such objects can damage the turbine. When installing the engine
in your aircraft model, cover the engine intake and exhaust opening, for example with
adhesive tape, to keep clippings and other objects from entering the engine.
-
Add 5 % of AeroShell 500 or AeroShell 560 turbine oil to the fuel. Use of a different
oil or a different mix-ratio will void the warranty.

as temperature, humidity of air density you will need to
adjust these values. A too hard of a throttle setting can
lead to overheating and blow-outs of the turbine.
↓
This parameter specifies the minimum voltage [V] for the
fuel pump at startup
. High voltage may lead to
unnecessary expulsion of flames; low voltage might keep
the turbine from starting up.
↓
This parameter specifies the voltage which the ECU will
calibrate to after startup. The ECU will calibrate the
turbines idle speed automatically; this value is only a
reference to adjust the ramp.

4. The turbines response curve is being calculated
Course of normal operation
Characteristic features of normal operation:
• Temperature/RPM dependent control of fuel feed
• Monitoring of RPM and temperature limits
• Recording of all relevant data (BLACKBOX)
• Telemetry transmission
Failsafe operation
The ECU comes with a failsafe setting which becomes active should rpm or temperature
sensors fail (Status: EMERGENCY). In this mode the turbine will be controlled by pumpvoltage alone. A pre-occurring one-time stabilization of full throttle is necessary (Status:
AUTO-HC). The cause of error needs to be eliminated before the turbine can be started again.
Safety features
• RPM: exceed – fall below - failure
• Temperature: exceed – fall below - failure
• Power: Minimum voltage
• Output Fuel pump: failure/short circuit
• Input receiver: failure –glitch –Fail Safe
25
Hammer Engines GmbH / IQ-Serie / Instruction Manual
Radio equipment
Throttle
The turbine is operated by the throttle channel:
• Startup initiation
• RPM / thrust control during flight
• Shut down
You have to teach the transmitter before operating the turbine for the first
time or after reset to factory setting!
Turbine startup:
1. Throttle trim and throttle stick to minimum
2. Throttle trim and throttle stick to maximum - STANDBY
3. Throttle stock to minimum
4. Throttle stick back to maximum within a 3 second window -> STARTUP
RPM/Thrust control
Once the turbine has successfully started and finished the calibration process the turbine can
be controlled by the throttle stick.
Shutdown
Throttle stick and trim to minimum, this will initiate the shutdown sequence.
Transmitters with digital trim
We recommend mixing a switch in with your throttle channel to enable a quick „minimum
throttle trim “sequence.
FAIL SAFE / Receiver glitch
The ECU continuously monitors whether the throttle signal is valid and within limits. When
you teach the transmitter you are setting upper and lower limits. Should there be a command
below or above set limits the system will go to failsafe. Status display 1 will read „ –FAIL“
instead of a valid throttle readout in %.
FAIL SAFE Settings in Menu 3.4
FAILSAFE DELAY:
Delay between first occurrence of glitch or bad command and initiation of failsafe thrust
(Menu point FAILSAFE THRUST).
26
Hammer Engines GmbH / IQ-Serie / Instruction Manual
FAILSAFE TIMEOUT:
Time between initiation of failsafe trust and complete shutdown, should the glitch or bad
command continue.
FAILSAFE THRUST:
Once the FAILSAFE DELAY has passed the turbine will go to this preset rpm.
Deactivation of the FAIL SAFE Function:
Should you set the value for FAILSAFE DELAY to 0.0 sec, Fail Safe Thrust will be
deactivated.
PCM Transmitter/Receiver FAIL SAFE Settings:
In order to recognize a Fail Safe using PCM radio equipment the radio will have to emit
signals in case of a failsafe that are outside the learned limits. Hence, should you have taught
100% positive and 100% negative travel, then failsafe has to be set to negative 110% and
positive 110%. Please see your radios manual.
Auxiliary channel
Functions as an on/off switch:
ON/OFF Switch (Replaces trim):
The auxiliary channel replaces trim, switch ON = trim up / switch OFF = trim down. Please
note that trim needs to be set to maximum should you want to use this switch function!
Smoker-Valve:
A connected smoker can be operated. This channel will be activated above 300 degrees
Celsius.
Connect the ECU to the receiver using a 1:1 servo cable (PATCHCABEL) on AUX.

PURCHASE AGREEMENT, FULL ASSUMPTION OF LIABILITY AND
INDEMNITY AGREEMENT
Buyer purchases from Hammer Engines GmbH, a Limited Liability Company or from one of
Hammer Engines GmbH authorized dealers, a MINIATURE TURBOJET ENGINE for model
aircraft, cars or boats ("Model Engine") for the invoice price, accompanying this sale, and
Buyer and Vogelsang Aeroscale agree to all of the following terms and conditions:
1. Buyer's Representations. Buyer represents that he/she is very experienced in model
airplane operation, and that all of the information set forth in the Purchase Application is true
and correct. Hammer Engines GmbH relies on such representations, and would not enter into
this sale but for these representations.
2. Buyer's Acknowledgment of Risks and Dangers. Buyer recognizes that operation of the
Model Engine may be dangerous, and that under certain circumstances, its handling will be
dangerous. As set forth in Paragraph 3 below, Buyer accepts full responsibility for all of these
risks and waives all liability as against Hammer Engines GmbH.
(a) Buyer's Acknowledgment of Danger. Buyer expressly acknowledges that use of the
Model Engine is dangerous if improperly handled, and could inflict injury if attempts are
made to handle it properly, if the user does not fully acquaint himself/herself with the Model
Engine's operation procedures. The Model Engine may cause burns to the user, or the user's
assistant, particularly in the start-up procedure, and Buyer agrees to use extreme caution. The
Model Engine exhaust is extremely hot, and will burn someone or something placed directly
behind the exhaust tube. Highly flammable liquid is used to operate the Model Engine and it
or its fumes will ignite easily and flare up rapidly. The Model Engine itself remains extremely
hot, after it is shut off, and requires a cooling down period. Improper use of the Model Engine
or failure to follow Academy of Model Aeronautics ("AMA") guidelines and rules will result
in injury to the user, the user's assistant, or bystanders. Operation of the Model Engine in any
location other than an approved location, and under safe circumstances could lead to injury to
bystanders. A risk exists from explosion, in the event of tampering, modifications leading to
over-speed or extreme metal fatigue.
(b) Buyer's Obligation to Become Fully Acquainted With Operation Procedure. Buyer
acknowledges receipt of operating instructions for the Model Engine which depicts its
handling and operation. Buyer agrees to thoroughly acquaint himself/herself with these
materials, and to require his/her assistant to become equally familiar with them. Buyer
expressly agrees not to allow any person to assist in the start-up procedure of the Model
Engine, who has not become thoroughly familiar with these materials.
(c) Agreement to Use Qualified Assistant in Start-Up Procedure. Buyer acknowledges that
the start-up procedure for the Model Engine cannot be safely done, without an assistant.
Buyer expressly agrees to use an assistant, who is thoroughly familiar with the Model Engine
and its operation as set forth above, on each occasion when the Model Engine is started up.
(d) Warning to Bystanders. Buyer acknowledges that injury or burns to bystanders could
occur, during the start-up procedure or when operating the Model Engine. Buyer expressly
agrees to take all steps necessary to assure that no bystander will be in a position to receive
injuries during the start-up procedure, or while the Model Engine is running.
