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 IQ-
Hammer 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.
