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
