Page 3: Introduction
Should you still have doubts or questions, do not hesitate to contact CAT for further assistance. Once you are accustomed to handling the JetCAT P80, you will observe that it is a very reliable engine. Some experienced operators have expressed their belief that it handles better than many piston engines. -
Page 4: Safety Precautions
Obey all forest fire regulations and warnings by refraining from operating the JetCAT P80 in restricted fire zones. Never operate model turbine jet aircraft in or around residential or heavily populated areas. -
Page 5: The Checklist
Warning: A flying model with a turbine can reach higher flight speeds than ducted fan-powered models, because the turbine’s thrust degrades less with higher flight speeds. With attainable flight speeds of over 250 MPH, you can quickly run out if flying room. There is also a danger of developing control surface flutter or mechanical overload, causing the model to fail in flight. -

Page 8: Fuel / Fuel Care
Fuel / Fuel Care The JetCAT P80 can use Jet-A1, 1-K kerosene or deodorized kerosene for fuel. Fuel must be mixed with 5% synthetic turbine oil. Example formula: 1 quart of oil in 5 gallons of fuel. Oil brands like Aeroshell 500 or Exxon 2380 are suitable. -

Page 11: Filling The Starting Gas Tank
Important: The starting gas tank can be mounted vertically or horizontally. Whether the tank is mounted upright or on its side, the offset nipple must always be towards the top. This will prevent liquid propane from entering the turbine during startup. After every flying session, disconnect the release valve, before storing the model. -
Page 12: Mounting The Turbine
Mounting the Turbine A two-piece, aluminum mounting bracket is included with the turbine. Place the bracket around the turbine, with the glow plug situated within the slot of the smaller bracket piece. This will help stabilize the engine along the thrust axis. The glow plug must be in the vertical position, when mounted in your model (+/- 45°... -

Page 14: The Led I/O Board
The LED I/O Board The LED I/O (Input/Output) board is a connection point for the data bus and a display for the current status of the ECU. The board should be mounted with the LED’s visible and the data bus connector accessible for GSU plug-ins. The connector facing opposite of the LED’s is attached to the ECU. -
Page 15: Aligning The Ecu To Your R/C System
Aligning the ECU to your R/C System Before the Jet-Tronic ECU can be used for the first time, throttle stick and auxiliary control positions must first be programmed. To accomplish this, complete the following steps: 1. Connect the two ECU servo cables to the receiver. The “THR” cable connects to the throttle channel and the “AUX”... - Page 16 5. Now the ECU can memorize the positions of the throttle and AUX channels. First, place the throttle stick and throttle trim to low. Next, press Select Menu or the LED I/O board switch, again. This will store the R/C system’s pulse width for immediate shutdown of the turbine.
- Page 17 The GSU display will read: Set AuxChan. to à AUX channel middle “Start/Standby” position CENTER: - learn RC - 9. Set the AUX channel to the middle position for Start/Standby and press Select Menu or the LED I/O board switch again, to store the R/C system’s pulse width for the turbine to start and run.

Page 18: Manual Mode
Manual Mode During normal ECU function, the operator has no direct control of the fuel pump or fuel shutoff valve. To prime the fuel pump and fuel lines (or for fuel pump test purposes), it is necessary to open the fuel shutoff valve and run the fuel pump manually. For this purpose, the ECU has a special feature that opens the fuel valve and acts as a speed control for running the pump. -
Page 19: Turbine Starting / Running
Turbine Starting / Running 1. Prepare to start by completing the startup checklist (previously described on page 2. Briefly hold the model upward, to ensure there is no residual fuel in the turbine. 3. Set the AUX switch to the Off position. All LED’s will be off. 4. -
Page 20: Turbine Stopping / Cool Down
Turbine Stopping / Cool Down To shut off the turbine, there are two methods: Manual Off Turbine immediately turns off! At anytime, the turbine can immediately be switched off manually by: • setting the three-position AUX switch to Off • bringing the throttle stick to idle position, while bringing the throttle trim to its minimum position Auto Off Turbine automatically turns off! -
Page 21: Battery / Fuel Warning Function
50% level, it returns to the warning function sequence. Turbine Running States The JetCAT P80 progresses through several operating states, from ignition to the cool down process. The transitions of these states are automatically controlled by the ECU and by user commands. - Page 22 If one of these conditions exists, turbine proceeds to the next operant condition (AccelrDly). If the P80 doesn't ignite after several attempts (within the pre- programmed time), the ignition state is discontinued and the turbine will shift to the SlowDown state.
- Page 23 RUN (reg.) Turbine in the normal running state; the throttle stick will regulate turbine thrust. During this operant condition, the green OK LED will illuminate, indicating that pilot has control. RUN (reg.) continues, until the turbine is switched off. AutoOff The AUX switch placed in the AutoOff position.

Page 25: Ground Support Unit (Gsu)
Ground Support Unit (GSU) The GSU serves as a terminal for displaying and programming turbine parameters. It may be connected or disconnected at any time. The real time nature of the ECU allows the operator to adjust the turbine’s parameters, even when the turbine is running. -

Page 34: Airspeed Sensor
Airspeed Sensor The optional Airspeed Sensor consists of a pitot tube and a precision, differential pressure sensor. By sampling the ambient air temperature, the current flight speed of the model is calculated by the ECU, from the measured difference in static versus dynamic pressure. When the ECU is used without the Airspeed Sensor, it is set in thrust control (normal) mode. - Page 35 Connection diagram for the Airspeed Sensor: flig h t d i r e c t i o n S ta tic p r e s s u r e Airspeed Sensor Dyn a m ic p re s s u r e P ito t tu b e E C U c o n n e c tio n c a b l e Connect the air lines from the pitot tube to the airspeed sensor, using the 1/16...

- Page 38 Lrn Speed Lo Learns the slow flight speed. If the AUX switch is momentarily placed in the SW0 position, the current flight speed is assigned and recorded as the Min.AirSpeed parameter. WARNING: When the AUX switch is set in the SW0 position, the model must be flying faster than 40 km/h, otherwise the turbine will shut off.
- Page 39 In this configuration, the pitot tube should stand off from the fuselage, by at least two (2) inches. Because each model installation is different, Golden West Models and JetCAT will have additional mounting information for review, as auxiliary data becomes available.
