Testing and verifying the failsafe, verification can be performed either by

starting the turbine or using the HDT display.

Verification by Starting the Turbine

1. Start the engine. Set the power to any setting above idle.

2. Turn off the transmitter but leave the receiver on and engine running.

Verify that the engine power goes to idle after 0.5s and shutdown after 2 s. If signal

from TX is re-gained during these 2s, power will return to normal.

Note: this is only valid when using non 2.4 GHz equipment, with 2.4 GHz equipment

the Turbine will shut down immediately with the powering down of the transmitter, the

reboot time of the power up sequence is longer than two seconds therefore signal

cannot be regained in the time allotted.

6 Starting the engine

Always test the turbine on a test bench before installing it into the plane, this will confirm that

all systems work as they should, and you will be able to learn its operation and the

emergency procedures. A suitable platform/table/workbench is required to clamp the test

stand onto. Make sure this can be easily transported outside and weighs enough to ensure it

cannot be blown over by the thrust of the engine.

Select a clear area for running – keep clear of areas with loose leaves, sand or other debris

that could be picked up or drawn towards the intake. Ensure the fuel tank is position well

clear of the exhaust area and is secured.

The kerostart system used on all Jet Central turbines is reliable and well tested system that

produces very smooth and trouble free starts. However, extra care and attention must be paid

when starting a kerostart turbine.

The main difference between gas and kerosene starting is that in the case of a failed ignition,

with gas starting the gas dissipates quickly in the air and isn't kept inside the engine

Kerosene is liquid and, if unburned, will pool inside the engine and stay there. The engine can

hold a large 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 turbine, but can destroy the model.
