Safety Precautions
ALWAYS ENFORCE THE PROPER MINIMUM SAFE DISTANCES FROM THE TURBINE!
In front = 15 feet On the side = 25 feet Behind = 15 feet
Fire extinguishers should be on hand at all times. We recommend the CO2 variety.
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 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 or within the fuselage. Objects being sucked in will cause severe damage.
Always exercise caution around the hot parts of the turbine, to avoid burns. The
outer case at the turbine stage and nozzle reaches 450-500° (Celsius), while the
exhaust gas may exceed 720 °C.
Assure that the fuel is mixed with approximately 5% synthetic oil. Use only synthetic
turbine oils available at local airport fuel suppliers.
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 turbine in restricted fire zones. Never operate model
turbine jet aircraft in or around residential or heavily populated areas.
Installation of unauthorized parts from another manufacturing source may also result
in engine failure
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,
