2.4 Fuel / Oil System
The Fuel/Oil is pre mixed together. Where the fuel line connects to the motor a T-fitting sends
some of the Fuel/Oil to the bearings and the rest is sent to the fuel nozzles in the combustion
chamber. It is important to filter the fuel and use proper types of fuel in the turbine Engine.
Without proper filtering one or more of the injector needles could become clogged, thus
affecting the proper running of the engine. Only synthetic turbine engine oil is to be used and
MIXED TO THE PROPER AMOUNT of 2.5% or 16 US ounces per 5 US gallons fuel.
2.5 Starting Gas System
When you choose “AUTO – GAS” option in the Start Menu.
In the initial start sequence, the motor uses propane or a propane/butane mixture. This
system uses an onboard gas tank and a solenoid valve to deliver the gas to the combustion
chamber, the glow plug is powered momentary to cause ignition. When certain parameters
are meet the fuel solenoid valve is opened by the I.C.S. and then fuel is used to bring the
engine to the proper idle RPM during the remaining ramps. The gas valve is automatically
closed when a certain RPM is reached during the fuel ramp.
2.6 Kerostart System
The main difference between gas and kerosene is that in the case of a failed ignition, the gas
dissipates quickly on the air and don't keep inside the engine. Kerosene is liquid and, if
unburned, will pool inside the engine and stay there forever. The engine can hold a big
quantity of kerosene inside. This kerosene will be ignited on next successful start up and will
be pushed to the exhaust as soon as the airflow inside the engine is sufficient, and will be
ignited in the exhaust, causing a hot start (in extreme cases a big fireball) that will not hurt the
engine, but can destroy the model.
2.7 Hand data Terminal (HDT)
The Hand Data Terminal is simple and easy to operate. The HDT is used to read the different
information and to program certain parameters in the
I.C.S.,
this is a link between the user
and the
I.C.S.
Make sure to take the necessary time and learn the operation, as this is the
only exact way the operator can monitor and check that the turbine is running properly. The
unit is small and compact, but always remove it before flying.
Note: If you leave it installed, remember it uses power from your RX battery.
