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
The Checklist Before Running the Turbine • Charge ECU Battery • Prepare fire extinguisher • Check fuel lines and filter. Make sure they are clean with no restrictions • Check that the fuel tank vent is unobstructed • Mix 5 % oil in fuel (i.e.: 1 quart per 5 gallons of kerosene) •... -
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. -

Tank Fill 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 20: 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 21 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 23: 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 24: 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 (+/- 75°... -
Page 25: Power Supply
300-400 mah. 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 26 Note: 2 coils pulled out 90° from the body If you have been enjoying good auto starts, and suddenly you notice that your turbine does not start immediately on the first starting gas cycle, check the glow plug. The plugs last so long that we sometimes forget that they can finally wear out!

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 30: Jetcat Ecu Version 4.0 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 31: Setting Up The Ecu
Setting up the ECU These are the first steps you need to complete before operating the v4.0 ECU. Make sure your batteries are charged, the ECU is off and the GSU is connected.
