Safety Notes
✔ Always have a fully functional CO
weight at hand.
✔ Only test the jet engine at suitable places outdoor and observe the applicable laws
and regulations.
✔ Always keep the following safety distances from the running jet engine
(1 m = 3 ft, 10 m = 30 ft, 12 m = 36 ft):
✔ Never look directly into the exhaust jet and never touch it 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 swarf 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/swarf and other objects from entering the engine.
✔ Make sure that about 5 % of turbine oil is added to the fuel. Only use special aircraft
turbine oil.
