3 Introduction The jetcraft RC model jet engines by Modellsport Schweighofer have the same functional principles as their big counterparts. A high performance compressor compresses the ingested air, which is then heated by fuel flame in the combustion chamber and the heat causes the air to expand rapidly, enabling it to drive an axial turbine rotor, which in return drives the aforementioned compressor via a shaft. This is called a closed loop setup. The hot air leaves the engine at the exhaust cone at a speed in excess of 1000 km/h (621 mph), generating the necessary thrust for the jet aircraft model. An electric starter motor and a new electric kerosene ignition system allow for a fully automated engine control setup using nothing but your transmitter. The system is controlled and monitored by the jetcraft-ecu control unit, which checks and controls all parameters for their optimal values. This new generation of model jet engines no longer requires auxiliary gases such as propane or butane. The system and all of its components such as the fuel pump, kerosene ignition, valve and so forth are powered by a separate. The jetcraft jet engines share the basic outer dimensions with their predecessors yet offer more power (90N-180N). The latest in CNC- and laser cutting technology allow for unprecedented standards in precision, material properties and mechanical characteristics, ensuring both the highest performance as well as durability. The included display/ programming unit (EDT or Engine Data Terminal) comes equipped with an illuminated LC-Display and can be connected to (and disconnected from) the running system at any time of operation in order to check on the current operating data readouts or in order to change parameters. Besides current and effective operating parameters such as exhaust gas temperature (EGT), turbine revolutions per minute (rpm) and thrust (throttle), additional information such as total hours of operation, rpm and temperature statistics, number of engine starts, battery voltage and so forth can be read out and displayed. All parameters and inputs are displayed in plain text in the menu-based interface. The turbine is being started fully automatically via the transmitter s throttle stick. The pilot then adjusts the desired thrust by moving the stick proportionally. The jetcraft control unit is connected to the R/C receiver via the R/C-1 output. 3

4 SAFETY PRECAUTIONS Welcome to the Jet Age of RC model aircrafts! Never forget: Operating a jet engine like the jetcraft can be dangerous. An aircraft model equipped with the jetcraft can reach speeds of more than 400 km/h (250 mph) and temperatures up to 500 C (930 F) at the engine housing and up to 750 C (1380 F) at the exhaust jet. Since it is a genuine jet engine, it requires know-how, discipline and regular service and maintenance for your own protection and that of other people. If other persons or animals are present while operating the jetcraft turbine, ALWAYS ENFORCE THE PROPER MINIMUM SAFE DISTANCES FROM THE TURBINE! Fire extinguishers should be on hand at all times. Modellsport Schweighofer recommends CO/2 (Carbon Dioxide) extinguishers of at least 5 pounds capacity. Powdered extinguishers will contaminate the precision components, upsetting the integrity of the turbine. To the avoid hearing damage, always use hearing protection when you are near a running turbine engine! When the turbine is running, never place your hands closer than six inches into the area of the intake. An extreme suction - which can grasp a hand, fingers or other objects in a flash - prevails in this area. Be aware of this source of danger, always! Prevent foreign materials from entering the intake or exhaust when working with the turbine. Before operation, make sure there are no lose parts or debris near the turbine. Objects being sucked in can cause severe damage. If you want to install and operate this jet engine in your model aircraft, you must be trained in its handling and very experienced in model airplane operation in general. The model with the jet engine should only be operated under supervision of an experienced person who can support you in order to avoid mistakes. If there is a local R/C club in your area offering training and support, we recommend that you become a member. Mistakes made during the assembly or operation of a jet-powered model aircraft can lead to serious injuries or even death. Always observe the law. Before operating a model aircraft with this jet engine, you should be informed about the legal regulations regarding such aircraft. From a legal point of view, a model aircraft is considered an aircraft like any other in most countries and is subject to the corresponding laws, which must be observed by all means. Please check the applicable air traffic laws of your country carefully before flying your model. Your local R/C club will likely be able to provide you with the required information and documents. In many countries, jet-powered model aircraft require a special license and/or a special insurance. Furthermore, regulations regarding the protection against interference between R/C transmitters and radio networks must be observed. Please make sure to comply with all applicable laws and regulations in your country. It is your responsibility to protect others against injuries. The operating distance of your aircraft from residential areas must be at least 1.5 km (1 mile) in order to ensure the safety of people, animals and buildings. Keep a safe distance from power lines. Never fly your model in bad weather with low clouds or fog. Never fly directly against the sunlight otherwise you might lose visual contact with your model. To avoid collisions with manned or unmanned aircraft, land your model immediately if an aircraft is approaching. Persons and animals must keep the following minimum distance to the jet engine (see also the figure on page 6): In front of the engine: 1 m (3 ft) At the sides of the engine: 12 m (36 ft) Behind the engine: 10 m (30 ft) 4

5 Assure that the fuel is mixed with approximately 5% Aeroshell 500 or Aeroshell 560. Synthetic turbine oils are dangerous and should only be handled per the manufactures MDS sheets. Never run the turbine in a closed room, or an area near any kind of flammable matter. Do not fly turbine-powered aircraft near flammable materials, nor in forested tracts or areas experiencing drought or dryness. Obey all forest fire regulations and warnings by refraining from operating the jetcraft turbine jet aircraft in restricted fire zones. Installation of unauthorized parts from another manufacturing source may also result in engine failure. Do not introduce engine or electronic components other than those delivered by Modellsport Schweighofer, unless you are willing to risk destroying your turbine! Modellsport Schweighofer s parts are designed and engineered specifically for the jetcraft engines. Accept no substitutes, unless you are prepared to sacrifice your aircraft. 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. When piloting a turbine powered aircraft, one must properly control the throttle. Full power should be used for takeoff or vertical maneuvers and a reduced setting for level or descending flight. To restrict the maximum flight speed, an optional airspeed sensor is available. The jet engine may only be operated in exact compliance with the instructions found in this manual. Furthermore, the specifications of the aircraft model regarding the centre of gravity and rudder travel as well as all information in regards to construction and materials as well as components used must be adhered to. Before flying a model jet aircraft equipped with the jetcraft turbine all functions and all rudders as well as the range of the R/C transmitter must be tested with the transmitter turned on and the antenna retracted or set to Range check output in case of a 2.4 GHz system. This range test must be repeated with the jet engine running while another person is holding the model in place. Furthermore, the instructions by the R/C system manufacturer must be followed closely. Any deviation from the specifications in this manual, the use of non-approved parts or materials or modifications to the system construction or setup can have a negative effect on the functionality and safety of the jet engine and must be avoided by all means. Warning: It is strictly forbidden to operate the model and/or the jet engine under the influence of alcohol, drugs etc. The jet engine may only be handled by persons in excellent physical and mental condition and with utmost concentration. This applies to the operator as well as any assistants. This jet engine was designed solely for use in model aircraft and is not suitable for any other purpose. Never use it to transport persons, objects or vehicles other than a suitable jet model airplane as any other forms of use can or will lead to personal injury or even death. 5

6 Only test the jet engine at suitable places outdoor and observe the applicable laws and regulations. Always enforce the proper minimum safe distance from the turbine: Never look straight into the exhaust jet and never touch it or the exhaust stream with your hands. Whenever possible, wear hearing protection. Keep away from the engine intake (electric starter). The air stream has an enormous suction power, which can lead to severe injuries. After the first installation, and afterwards in regular intervals, test the transmission range of your R/C system with the jet engine running. Before operating the engine, remove all loose objects near the engine intake, such as cleaning cloths, screws, nuts, cables or other material. Before operating your model for the first time, make sure that there are no loose objects in the engine intake, such as clippings, screws or debris from building the model. Such objects can damage the turbine. When installing the engine in your aircraft model, cover the engine intake and exhaust opening, for example with adhesive tape, to keep clippings and other objects from entering the engine. Add 5 % of AeroShell 500 or AeroShell 560 turbine oil to the fuel. Use of a different oil or a different mix-ratio will void the warranty. Use only Aeroshell 500 oder 560 Oil! 6

9 Checklist for the first time of Operation Install and connect the components according to the installation plan (see page 8). Pay special attention to the correct connection of the FUEL valve and to a proper plumbing of the tubes without kinking them. The arrow on the fuel pump and the valve indicate the flow direction of the fuel to the engine. The QS quick connectors (blue) should snap in when you plug in the tube. The tube can only be released by pressing on the blue ring while pulling the tube out. Only use approved PUN/ Festo tubes with a diameter of 4 mm (0.16 ) or 6 mm diameter (0.236 ), respectively. Charge all batteries, paying special attention to the correct charging program for the lithium manganese battery, i.e. a maximum charging voltage of 12.6 V. Use the 3s LiPo charging mode of your charger at 1 2 Amps. Check the temperature sensor to the environment temperature via the parameter Menu 2-ADJUSTMENTS 2.3 ADJUST TEMP AMBIENT TEMP Teach the remote control: OFF, IDLE, 100 %, via the menu 2 ADJUSTMENTS 2.1 LEARN RC TIMING make adjustment. Open the fuel tank ventilation, then fill the fuel tank(s) with fuel containing approximately 5 % of AeroShell 500 or AeroShell 560 oil Have a CO2 fire extinguisher at hand! Turn on the R/C transmitter, and then turn on the receiver. Place your aircraft model with the nose into the wind. Start the jet engine (keep a safe distance, see page 6!): 1. Throttle down + trim down => remove LOCK 2. Trim up => RUN cleared 3. Throttle up and down again => AUTOSTART activated, see EDT display. Checklist for Turning the Engine Off Place the aircraft model with the nose against the wind. Turn the jet engine off: Throttle down + trim down (below 25%) => -OFF Wait until the automatic cool-down procedure of the engine is finished. Check the INFO data about the operating states (see page 14 ff). After finishing the flight activities, remove all fuel from the tank(s) and close the fuel tank ventilation. 9

16 Menu and Settings To enter the max revolution speed of the turbine To enter the min revolution speed of the turbine This parameter specifies the acceleration/ throttle-up time (more thrust) and deceleration/throttle-downtime (less thrust) of the engine. Depending on ambient factors such as temperature, humidity of air density you will need to adjust these values. A too hard of a throttle setting can lead to overheating and blow-outs of the turbine. This parameter specifies the minimum voltage [V] for the fuel pump at startup. High voltage may lead to unnecessary expulsion of flames; low voltage might keep the turbine from starting up. This parameter specifies the voltage which the ECU will calibrate to after startup. The ECU will calibrate the turbines idle speed automatically; this value is only a reference to adjust the ramp. 16

17 This parameter specifies the maximum allowed voltage [V] for the fuel pump. Do not confuse this value with pump-voltage at 100% throttle. This value is only being used in order to identify failure. Should this limit be exceeded the pump will be switched of automatically! The set voltage should be a tad above 100% throttle V. Please be aware, should the set voltage be too low the turbine will not reach max revolution speed and the turbine might go into auto-shutdown! This parameter adjusts throttle exponential from 0% to 100% 17

18 The ECU must be calibrated to your transmitter. Please follow these instructions: 1. THRO. LO/TRIM LO: Set throttle and throttle trim to minimum -> press 2. THRO. LO/TRIM HI: Set throttle trim to max, leave throttle stock at minimum -> press 3. THRO. HI/TRIM HI: Set throttle stick to max, leave trim at max -> press Done. Should there be a auxiliary function present (ON/OFF or Smoker-Valve) you will have to teach the auxiliary-function as well. This is being followed by a plausibility check. Should there be a failure followed by an alarm tone you will need to correct the cause for failure and calibrate again. In most cases the transmitters programming is at fault. Calibration of the Heat Element In order to use the fuel flow readout display you will need to enter throughput at 1 Volt and 2 Volt (FUEL- pump voltage as well as enter the size of your fuel tank in order to enable the calculation of the remaining fuel at any given time. 18

19 Input the minimum and maximum battery voltage. This will determine at what thresholds the unit will read out Battery Full or Battery Empty. Choose the language you want the unit to be set to. Shows the total operating time Sets up receiver fail-safe mode (see the corresponding section in this manual) Should you be running a auxiliary-channel you can input its function here. Possible choices : NO FUNCTION Auxiliary-Channel not being used ON/OFF SWITCH The Auxiliary-Channel replaces the throttle trim function SMOKER VALVE: A Smoker Valve can be operated. Please note that this function will only be active above 300 degrees Celsius. 19

24 Auto-Calibration procedure 1. Ramp up to calibration rpm 2. Stabilization 3. Idle rpm are being adjusted 4. The turbines response curve is being calculated Course of normal operation Characteristic features of normal operation: Temperature/RPM dependent control of fuel feed Monitoring of RPM and temperature limits Recording of all relevant data (BLACKBOX) Telemetry transmission Failsafe operation The ECU comes with a failsafe setting which becomes active should rpm or temperature sensors fail (Status: EMERGENCY). In this mode the turbine will be controlled by pump-voltage alone. A pre-occurring one-time stabilization of full throttle is necessary (Status: AUTO-HC). The cause of error needs to be eliminated before the turbine can be started again. Safety features RPM: exceed fall below - failure Temperature: exceed fall below - failure Power: Minimum voltage Output Fuel pump: failure/short circuit Input receiver: failure glitch Fail Safe 24

25 Radio equipment Throttle The turbine is operated by the throttle channel: Startup initiation RPM / thrust control during flight Shut down You have to teach the transmitter before operating the turbine for the first time or after reset to factory setting! Turbine startup: 1. Throttle trim and throttle stick to minimum 2. Throttle trim and throttle stick to maximum - STANDBY 3. Throttle stock to minimum 4. Throttle stick back to maximum within a 3 second window -> STARTUP RPM/Thrust control Once the turbine has successfully started and finished the calibration process the turbine can be controlled by the throttle stick. Shutdown Throttle stick and trim to minimum, this will initiate the shutdown sequence. Transmitters with digital trim We recommend mixing a switch in with your throttle channel to enable a quick minimum throttle trim sequence. FAIL SAFE / Receiver glitch The ECU continuously monitors whether the throttle signal is valid and within limits. When you teach the transmitter you are setting upper and lower limits. Should there be a command below or above set limits the system will go to failsafe. Status display 1 will read FAIL instead of a valid throttle readout in %. FAIL SAFE Settings in Menu

26 FAILSAFE DELAY: Delay between first occurrence of glitch or bad command and initiation of failsafe thrust (Menu point FAILSAFE THRUST). FAILSAFE TIMEOUT: Time between initiation of failsafe trust and complete shutdown, should the glitch or bad command continue. FAILSAFE THRUST: Once the FAILSAFE DELAY has passed the turbine will go to this preset rpm. Deactivation of the FAIL SAFE Function: Should you set the value for FAILSAFE DELAY to 0.0 sec, Fail Safe Thrust will be deactivated. PCM Transmitter/Receiver FAIL SAFE Settings: In order to recognize a Fail Safe using PCM radio equipment the radio will have to emit signals in case of a failsafe that are outside the learned limits. Hence, should you have taught 100% positive and 100% negative travel, then failsafe has to be set to negative 110% and positive 110%. Please see your radios manual. Auxiliary channel Functions as an on/off switch: ON/OFF Switch (Replaces trim): The auxiliary channel replaces trim, switch ON = trim up / switch OFF = trim down. Please note that trim needs to be set to maximum should you want to use this switch function! Smoker-Valve: A connected smoker can be operated. This channel will be activated above 300 degrees Celsius. Connect the ECU to the receiver using a 1:1 servo cable (PATCHCABEL) on AUX. AUX-ECU RECEIVER 26
