Page 8: Introduction
Introduction Welcome to the Jet Age of model aircraft! JETCAT USA is pleased to sell, support and service the JetCat turbine engine and greatly appreciates your purchase. We hope the JetCat engine brings you many days of pleasurable flying. Obviously, model turbine aviation - despite all the apparent fun involved - is serious business. -
Page 9: Safety Precautions
= 25 feet Behind the turbine = 15 feet In case of a mishap, fire extinguishers should be on hand at all times. JETCAT USA recommends the CO/2 variety. Powdered extinguishers will contaminate the precision components, upsetting the integrity of the turbine. -
Page 10: 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 11: Fuel / Fuel Care
Fuel / Fuel Care The JetCat engine can use deodorized kerosene, 1-K kerosene or Jet-A1 for fuel. Fuel must be mixed with 5% synthetic turbine oil. Example formula: 1 quart of oil in 5 gallons of fuel. JetCat recommends Aeroshell 500 turbine oil. -
Page 12: Hopper Tank
Hopper Tank A hopper tank is recommended, between the main fuel tank and the engine. JetCat USA highly recommends the BVM UAT for the hopper tank! Always use the filter between the fuel pump and the solenoid valve as shown in the diagram. -
Page 13: Fuel System Connection Diagram
1/4 inch section of 4 mm (Kerosene) tubing acts as an adapter for large BVM UAT tubing Note: All tubing 4mm(except as noted) The UAT is available from JetCat USA,LLC or Bob Violett Models, Florida (407) 327- 6333. Page 13/74... -
Page 14: Fuel Pump Adjustment
Fuel pump adjustment After the turbine has ignited on propane, the starter motor further accelerates the turbine. At approx. 5000 RPM, the fuel pump is automatically started at minimum power by the ECU. Beginning from this first pump start voltage, the fuel flow is then slowly increased by increasing the pump voltage. - Page 15 Pump start voltage is adjusted too low: If the pump start voltage is adjusted too low, the pump may not start to turn ( the red “pump running” LED is illuminated, but the pump is not turning). This can result in the turbine, after ignition on propane, running an unusual long time and not picking up RPM.

Page 17: Filling The Starting Gas Tank
Filling the Starting Gas Tank: Only use a propane/butane mix for starting gas. JETCAT USA recommends Coleman POWERMAX fuel (or a mix of propane butane 60/40%). POWERMAX is available at sporting goods stores or from JETCAT USA. -
Page 18: Mounting The Turbine
For models that require an exterior turbine mount (such as the Kangaroo) or for bypass tube mounting, optional brackets are available from JETCAT USA. Suggested turbine installation Turbine side view / thrust tube When the turbine is mounted in models with the air intake at the bottom, for example F- 16, care should be taken to prevent foreign object damage of the compressor stage. -

ECU battery. The amount of battery capacity used per flight is approximately 300-400 mah (500-800 mah with the P180/P200). This includes starting and cool down. The ECU NiCad battery must be recharged after two (2) flights! JETCAT USA recommends recharging after every flight, making it a routine that is not overlooked. The battery should be cycled periodically, to prevent NiCad memory problems that lower the battery’s capacity. -
Page 24: 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 26: 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 plugging in the GSU. The connector facing opposite of the LED’s is attached to the ECU. -
Page 27: Jetcat Ecu Version 4.0 - 5.0 Introduction
This is the most significant update for the American market since our introduction of the JetCat engine, December 1998. This update replaces the processor board in the ECU with a new, totally redesigned board, utilizing the Hitachi H8 16 bit micro-controller. This very fast and powerful micro-controller allowed us to expand our already rich set of features and has a much larger capacity to expand in the future. -
Page 28: Setting Up The Ecu
Setting up the ECU These are the first steps you need to complete before operating the ECU. Make sure your batteries are charged, the ECU is off and the GSU is connected. Do not perform the calibration of the temperature probe if this is a new engine. Temperature probe calibration is for ECU updates only. -

One or two receiver channels may be used to control the JetCat ECU. If single channel is desired, follow these steps. - Page 32 :ON Turb Ctrl ON Aux channel enabled for speed limiter functions and/or Smoker. Turbine control enabled. :ON Turb Ctrl OFF Aux channel enabled for speed limiter functions and/or Smoker. Turbine control disabled. You still need to use the AUX channel for speed limiter and/or smoker functions but the turbine control will be in Single Channel Mode.

Page 33: Learn R/C". Teach The Ecu To The R/C System
“Learn R/C”. Teach the ECU to the R/C System Before the Jet-Tronic ECU can be used for the first time you must program the failsafe and learn the throttle stick and optionally the auxiliary control positions of your R/C system. To accomplish this, complete the following steps: 1. - Page 34 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 35 The GSU display will read: Set AuxChan. to AUX channel middle “Start/Standby” position center: 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.

As long as you do not power-down the system, you can down view the entire flight using the RS-232 adapter and a PC. If the off condition is "POWER-FAIL" then the data is not valid. This occurs if the ECU or receiver battery was disconnected or was intermittent or if the receiver power goes lower than 3 volts.

Page 59: Maintenance
Each JetCat has a prescribed maintenance interval. After approximately 25 hours, the engine should be returned to JETCAT USA (along with the ECU and fuel pump), for service. The total running time of the turbine can be accessed and monitored through the STATISTIC menu. -

Available options: Value Explanation Maintains the current flight speed. Hold-Speed Flight speed is measured at the time the AUX switch is placed in the SW0 position. - Page 68 Learn1s the slow flight speed. Lrn Speed Lo 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 69 In this configuration, the pitot tube should stand off from the fuselage, by at least two (2) inches. Because each model installation is different, JetCat will have additional mounting information for review, as auxiliary data becomes available.
- Page 70 Hold Speed and Cruise Control limitations: Under normal circumstances, the Airspeed Sensor is primarily used for limiting the maximum flight speed and/or recording the maximum and average speeds of the model. Nonetheless, Hold Speed and Cruise Control modes are clever additions. These modes require evaluating and adjusting the PID parameters in the limits menu, while flying the model with a different technique.
- Page 71 Calibration of the airspeed sensor The ECU calibration data of the differential pressure sensor can be aligned with software version V2.0g or higher. You will need the following items for this calibration: 1. 50-60cm of silicone tube or similar. The inside diameter is not important. 2.
