  • Page 5: Introduction

    Introduction Welcome to the Jet Age of model aircraft! JetCat is pleased to sell, support and service the JetCat turbine engine and greatly appreciates your purchase. We hope the JetCat turbine brings you many days of pleasurable flying. Obviously, model turbine aviation - despite all the apparent fun involved - is serious business. The JetCat turbine has undergone extensive testing and redesign, in order to ensure it is a safe and reliable model turbine;...
  • Page 6 Warning! In case of a mishap, fire extinguishers should be on hand at all times. JetCat recommends the CO/2 variety. Powered extinguishers will corrode the precision components inside the turbine and void your warranty.

  • Page 8: Quick Start Section For Rx Turbines With V10 Ecu

    Quick Start section for RX turbines with V10 ECU This section covers just the very basics to get your JetCat turbine up and running. However, it is not a substitute for reading and understanding the manual in its entirety. There are many great features and options not cover in this section that are fully explained later.
  • Page 9: Mounting The Turbine Support Equipment (Rx)

    Since the components of the new RX series engines are so small, the default cables lengths should work for most installations. If longer cables are needed, consider a battery cable extension with heavy gauge wire as the simplest approach.

  • Page 21: Single Or Two Channel Operation

    Turbine type, P100-RX in this example Single or two channel operation? The turbine may be operated with either one or two channels from your receiver (throttle only or throttle and an auxiliary channel). If single channel is selected, starting, stopping and controlling the power is all accomplished with just the throttle channel.
  • Page 22 If you look at the following servo travel graph below, you can see how the ECU detects a failsafe condition. The gray bar is the transmitters throttle channel end points set for +/- 100% travel. This is the travel range when setting the transmitter’s failsafe.
  • Page 23: Learn R/C". Teach The Ecu To The R/C System

    “Learn R/C”. Teach the ECU to the R/C System Before the 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: Connect one or both ECU servo cables to the receiver depending on either using single or two channel operation.
  • Page 24 The GSU screen will display:  Throttle channel “Idle” position Advance the throttle trim lever to maximum. Press Select Menu or the LED I/O board button switch again to store the R/C system’s pulse width for the turbine idle position. The red Pump running LED will turn off and the yellow Standby LED will illuminate.

    After each flying session, defuel the tanks before storing. WARNING! In case of a mishap, fire extinguishers should be on hand at all times. JetCat recommends the CO/2 variety. Powdered extinguishers will corrode the precision components inside the turbine and void your warranty.
  • Page 27: Starting And Stopping The Turbine

    Starting and stopping the turbine Prepare to start by completing the startup checklist. Single Channel Mode start/stop procedure. To start the turbine, place the throttle stick and trim to their minimum positions. Next, move the trim to its maximum position. Finally, move the throttle stick to its maximum position. When the throttle stick is set to the maximum position, the ECU will begin a fully automatic starting sequence.

    Turbine Running States The JetCat turbine 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. The current value is always displayed on the GSU screen in the STATE selection in the RUN menu. When the turbine is starting, the GSU will also display the current state on the bottom line of the display.

  • Page 47: 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 50 If the throttle stick is set at less than half throttle and the AUX switch is momentarily placed in the SW0 position, the current flight speed is assigned and recorded as the Min.AirSpeed parameter. If the throttle stick is set at greater than half throttle and the AUX switch is momentarily placed in the SW0 position, the current flight speed is assigned and recorded as the Max.AirSpeed parameter.
