GRAUPNER HARPOON II Mode D'emploi page 57

Welcome to the jet age for model aircraft!
Before you attempt to fly the model for the first time it is absolutely essential that you read right through the
operating and building instructions, and understand every part of the text. These notes are an integral part of the
operating instructions and should be stored away carefully together with the instructions. If you ever dispose of
the model, be sure to pass these documents on to the new owner.
Please note that operating the HARPOON is potentially an extremely hazardous activity. When powered by a
Graupner G 70 / JetCat P 80 / P 120 / P 160 jet engine the model is capable of airspeeds of 350 km/hr and
more. The case temperature of the Graupner G 70 / JetCat P 80 / P 120 / P 160 can be up to 500°C (Celsius),
and the exhaust gas temperature may even reach 720°C. These engines are genuine turbines, and it is essential to
study the instructions and warning notes supplied with your engine before you even attempt to run it.
The standard wing joiner for the HARPOON is an aluminium tube. This joiner tube is designed for normal flying
in conjunction with a Graupner G 70 / JetCat P 80, or other make of turbine rated at no more than 8 kg thrust. It
has adequate strength for this configuration.
If you decide to use a jet engine rated at more than 8 kg thrust, such as the JetCat P 120 / P 160, it is
essential to replace the standard wing joiner with the carbon fibre rod, Order No. 6264.220, and to limit
the turbine's thrust to 90% of the model's all-up weight.
In the interests of your own safety and that of others, the model must only be operated by experienced,
disciplined modellers with sufficient specialised expertise, and it must be serviced and maintained regularly and
competently. If you have no experience in building and operating models of this type, it is vital that you enlist
the help and advice of an experienced jet modeller if you are to avoid potentially catastrophic errors; this applies
in particular to the jet engine itself, which should only be run when an experienced operator is present. With this
model any defect or deficiency in its construction or operation can result in serious personal injury or even death.
CAUTION!
Before you operate this model aircraft you must determine the local by-laws and regulations which apply to you.
In legal terms our models are classed as aircraft, and as such are subject to legal regulations and restrictions
which must be observed. Our brochure "Luftrecht für Modellflieger" (Aviation Law for Model Flyers) contains a
summary of all these rules as defined under German law. Your local model shop should have a copy which you
can read. Models powered by jet engines require the landowner's permission before flying. Third party insurance
is mandatory. There are also Post Office regulations concerning your radio control system, and these must be
observed at all times. The rules vary from country to country; please refer to your RC system instructions for
more details. Third-party insurance is a basic essential, and it is your responsibility to ensure that it covers you
for the risks involved in flying model jets.
WARNING!
It is your responsibility to protect others from possible injury. Keep a safe distance from residential areas in
order to protect people, animals and buildings: at least 1.5 km "as the crow flies".
Keep well clear of high-tension overhead cables. Don't fly the model in poor weather, especially when there is
low cloud cover or fog. Don't fly the model directly into the sun, as you could easily lose visual contact with it.
To avoid collisions always keep well clear of full-size aircraft, whether manned or unmanned. It is your
responsibility to land immediately if a real aircraft approaches.
When operating the Graupner G 70 / JetCat P80 / P120 / P 160 jet engine you must keep people and animals a
safe distance from it. This means:
In front of the turbine
To the side of the turbine
Behind the turbine
