<div class="textblock">The JetCat P160 model jet engine works in the same way as its full-size counterparts. The single-stage radial compressor sucks in and compresses air, which is then mixed with fuel in the combustion chamber and heated. Combustion occurs, causing the air mass to expand greatly. The hot air then passes through an axial turbine wheel which in turn drives the compressor via a shaft. The exhaust efflux is accelerated to high speed (around 1100 km/hr) and leaves the tail end of the turbine, generating the thrust required to propel the model. An electric starter motor is fitted at the turbine´s intake funnel, and this is used to accelerate the turbine to the speed necessary for it to run. The engine is started and controlled fully automatically via a highly integrated electronic control unit (Jet-tronic ECU) which monitors and regulates the turbine's operation by measuring the turbine speed andexhaust gas temperature. Initial ignition of the turbine occurs using propane gas (lighter gas), which is fed to the engine from a miniature refillable tank in the model The gas is supplied to the engine automatically when the starting process is initiated. When ignition has taken place the electronic unit automatically switches the engine to liquid fuel (kerosene). All the electrical components are powered by a separate 6-cell battery; this is used for the auxiliary equipment such as the fuel pump, glowplug, starter etc. The external dimensions and weight of the JetCat P160 model jet engine are approximately the same as those of the JetCat P80 / P120, many thousands of which are now in use. Compared to the P80 / P120 the new engine delivers much higher thrust at around 160 N, and this is due primarily to the new compressor and turbine stages. These parts have been optimised for even higher air throughput, and it is these changes that have made it possible to generate a further increase in power (thrust) from the same size of engine. The enormous output power of this turbine makes it suitable for large models and those with a take-off weight of at least 14 kg. Please note: if it is installed in a lighter model aircraft (e.g. HOT SPOT, KANGAROO, HARPOON), the turbine's speed must be limited so that the thrust corresponds to no more than 90% of the model's weight. The display / programming unit included in the set features an illuminated alpha-numeric LCD screen (2 lines, 16 characters each), plus 10 operating buttons and 4 monitor LEDs. The GSU (Ground Support Unit) allows the user to read out the current operational data and also change the settings; it can be connected and disconnected when the engine is running. As well as showing the current operational data such as exhaust gas temperature, rotational speed and pump voltage, the GSU can also display statistical information such as overall fuel consumption, total turbine run time, maximum rotational speed, number of starts, duration and fuel consumption of the last turbine run, battery voltage etc. All information is displayed under menu control in a plain language dialogue. The turbine starts and ramps up to speed fully automatically when the operator gives a command from the transmitter. The pilot then controls the desired thrust proportionally using the throttle stick.<br />
The ECU is connected to the receiving system and uses two receiver channels: <br />
channel 1 is used for thrust control (throttle stick); channel 2 is assigned to a 3-position switch on the transmitter (alternatively rotary control or slider).<br />
The three positions of the switch are then used as follows:<br />
Pos. 0 = Turbine OFF: immediate engine cut (switch in back position)<br />
Pos. 1= Stand-by / Start, normal operation (switch in centre position)<br />
Pos. 2= Automatic switch-off (switch in forward position)</div>

<div class="headln">typical start procedure:</div>
<div class="textblock">1.Disconnect all refueling lines and outboard connections from the model.<br />
2.Switch on transmitter, receiver and JETRONIC (LOCK). <br />
3.Carry model to take-off strip. <br />
4.Move throttle stick and trim to "fully back" position (STOP). <br />
5.Move the trim to the forward position (RUN-).<br />
6.Move the throttle stick forward (REL-), then back to the "fully back" position (START SYSTEM ACTIVATED) <br />
7.The kerosene igniter glows briefly, and the turbine automatically starts and ramps up to speed. <br />
8.After about thirty seconds the engine is under the control of the pilot - ready for take-off!</div>
