Introduction Congratulations, you have just purchased a turbo-jet engine from KingTech Turbines, with the highest standards and technologies in turbine design and manufacturing. We will provide you with the best after-sales customer support and service to ensure you with many years of enjoyment with this new turbine engine. Obviously, model turbine aviation - despite all the apparent fun involved - is serious business.
Safety Precautions ALWAYS ENFORCE THE PROPER MINIMUM SAFE DISTANCES FROM THE TURBINE! In front = 15 feet On the side = 25 feet Behind = 15 feet Fire extinguishers should be on hand at all times. We recommend the CO2 variety. 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 into the area of the intake.
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.
The Checklist Before Running the Turbine Charge ECU Battery Observe all safety precautions on Page 10 Prepare fire extinguisher Check fuel lines and filter. Make sure they are clean with no restrictions Check that the fuel tank vent is unobstructed Fill fuel tank(s). Make sure the main and header tanks are full Prime pump.
Fuel System The input and output fuel tubing must be connected to the electronic shut-off valve as per the diagram on page 16. When installing the fuel lines on components with barbed connectors, slightly heat the tubing and lubricate the barbes before connecting. This will soften the tube, making it much easier to install. Double looping safety wire on all barbed connection is also required. To remove tubing from barbed connectors, you must cut the tubing off.
Hopper Tank A hopper tank is recommended, between the main fuel tank and the engine. Kingtech highly recommends the BVM UAT or its equivalent for the hopper tank! Always use the filter between the fuel pump and the solenoid valve as shown in the diagram.
Fuel System Connection Diagram Fuel pump adjustment Pump Start point: Sets the power of the pump when it is started at beginning of the fuel ramp. The FADEC has the ability of to automatically adjust the pump power to start it at the lowest possible speed, independently of the battery voltage and pump roughness. AUTO mode: The values of “Pump start point” from 0 to 8 are in AUTO mode. This means that the FADEC will adjust itself the pump power to start it slowly.

Gas installation Some modelers prefer onboard gas installation. When setup correctly no connections to jet is needed when startup. If you will not use onboard gas, then you may skip these steps. Keep the tubing length short from the one/way valve to the black nylon starting gas probe. This will minimize the amount of excess gas released when the probe is removed from the POWERMAX can. The starting gas tank can be mounted vertically or slightly horizontally.
liquid stops flowing, remove the probe from the POWERMAX can. Several starts are attainable with a full tank. Do not over fill the on-board starting gas tank. When you notice the liquid flow into the tank start to slow down, stop filling. You will prevent any tendency to "pop" on start up, while still having enough gas for 6 to 8 auto starts from a 4oz. bottle. Mounting the Turbine A two-piece, aluminum mounting bracket is included with the turbine.
Connections at the turbine Notice the white dot side has only two polarities, which goes to the thermo port.
ECU Battery (not included) Power for all electrical components of the turbine (starter / glow plug / ECU / fuel pump / fuel and gas valves) are supplied by 2 cell lipo 2000mah to 5000mah ECU battery. The amount of battery capacity used per flight is approximately 300-350 mah. This includes starting and cool down. The ECU battery must be not be used over 80% of its capacity, otherwise must be recharged.
Charging the Battery - Do not charge the battery, with a quick charger using negative discharge pulses, when connected to the ECU. This will destroy the electronics of the ECU. The only recommended method is to disconnect the battery from the ECU and charge it directly. Also make it a routine to reset battery used to zero under Info menu by pressing the “+” button after each full charge.
speed. It monitors all of the controls necessary to guarantee that the engine stays between the user defined parameters of operation, also providing failsafe shutdown of the engine when it has detected any important anomaly. In order to make this assessment, the FADEC has a rpm sensor, a thermocouple input, a throttle servo input, power connections for the fuel pump, starter, glow plug, fuel and gas valves and the battery and a digital (RS232) serial port to program and read the data in realtime to a PC.
changing the data. Main screen, as shown in the picture, give to the user that main readings from the engine. These are the FADEC status, the EGT (temperature), RPM and Fuel Pump pulse width (Pw) In the case of an error, this screen changes to the error screen every 2 seconds. Pressing the second button from the left (Menu Up) the second information screen is shown. In the first line you have the measure of the pulse width received from your RC system, and the relative stick position.
Radio: Programming the transmitter throttle and trim throws, and setting of throttle curve. Run: Set the parameters used during engine run. It is recommended to program the learn RC first. Learn R/C. Teach the ECU to the R/C System Learn RC (throttle stick and trim travel) on Xicoy ECU just doesn’t get easier. First, please set stick low and trim low on transmitter and power on transmitter, and receiver. Power on ECU plug in GSU, scroll and select “Radio” then just follow directions on the screen.
On your first start after RC learned: Be patient until ECU stabilizes idling RPM, this may take up to 1 minute or so, subsequently hold on tight to your airplane and apply full throttle, and again let the ECU to stabilize its peak RPM, then back down to idle to verify, do this a few times and you are ready to go. Throttle curves By default the FADEC controls the RPM in linear way, i.e. at half stick position the engine turn at half of the rotor RPM range.
Test functions The FADEC provides testing functions to the starter motor, glow plug, pump and both solenoid valves. These test screens are only available when the FADEC is on “Trim Low” status, that is to say, recently powered up and receiving a STOP signal from the TX. Pressing the (-) button (under the “ON” reading on the screen) will energize the selected device and pressing (+) will shut down.
Turbine starting and running Always set-up and confirm the operation of your Auto-start installation on the teststand, before installing into your model. The present version of auto start uses only one channel for the entire engine functions: To trigger the auto start cycle, the process is as follows: • The user raises the trim. "Ready" will appear on the GSU screen. The trim and stick should be where the engine is supposedly to be to idle once running.
engine continues to accelerate until idle RPM is reached. Now, the command of the turbine will be taken over by the transmitter. Turbine stopping and cooling • The user can finish the sequence at any moment, simply setting the trim to "off" position. If the engine was on "running" phase (above idle rpm), a cooling sequence will be triggered, cycling the starter motor until the EGT is below the minimum programmed temperature. This cooling sequence will be aborted if the trim is raised again.
Idle speed: Set the RPM that the engine will run when the FADEC receive IDLE Command. While the engine is running, the FADEC will adjust the rotor speed accordingly the throttle position in a closed loop system. (45,000 for the K-80 and 36,000 for the K-170) STOP speed: Set the minimum RPM that the engine is allowed to run. The FADEC will shut down the engine if the rotor speed is below this setting.
circuit that can cause leaks or blown tubes. Modifying this parameter is similar to reducing the battery voltage, so the accel and decal times will be modified. The most ideal is to have the limit set at the lowest and still be able to reach full max RPM, run the engine, check and annotate the Pw of the pump displayed on the first screen when the engine is running at full power and then use this value as pump limit, increasing it in a 15%-20% to give a bit of margin for weak batteries and pump wear.
List of FADEC Warning message codes: RC SIGNAL LOST/INCORRECT: The signal received from the RX is wrong (outside calibration margin) or absent. PUMP LIMIT REACHED: The FADEC has increased the pump power up to the value set on the “Pump Limit” parameter, but the engine has not arrived to the full power. Causes could be flat battery, fuel restriction or anything that can cause a reduction in the fuel flow. xxxx OVERLOAD: An excessive current is detected from the specified output.
FlameOut: The engine has been shutdown because the temperature has dropped below the minimum of (100ºC). (Usually a thermocouple failure). RCPwFail: Lack of power from the radio receiver.

FADEC system - Autostart 10 Users Guide. Torrent d’en Puig, 31. 08358, Arenys de Munt, Barcelona,Spain E-mail: info@xicoy.com. Fax: +34 933 969 743 web: www.xicoy.com © Copyright 2010, Xicoy Electronica SL.
Welcome! Congratulations on the purchase of your new FADEC 10 controller. Xicoy are dedicated to the design and production of electronic controllers to the highest standards of quality and reliability to bring you the customer the very latest next generation designs. The FADEC 10 is the result of an intensive effort of design and tests. PLEASE READ! The Xicoy Electronica SL responsibility is limited exclusively to the repair of the FADEC and accessories which are outlined in the conditions of warranty.
Description of the FADEC. The FADEC (Full Authority Digital Engine Control) is a total system for the control of a model gas turbine engine. Its main function is to control and regulate the electric fuel pump, providing to the turbine engine the necessary amount of fuel for safe and controlled operation, and to operate the ancillary devices for starting. The FADEC measures the exhaust gas temperature, the relative position of the throttle stick and the rotor speed.
Connections: The FADEC have 3 types of connections: Power connections: Two high quality MPX connectors carry all the power current. Each power lead is identified by the label on the FADEC body. The female MPX plug provides the power to the glow plug and starter motor. Use 0,5mm flexible cooper lead if the length is up to 0,5m, and 1mm if higher for Gas start engines, 1mm2 minimum for Kerostart burner.
Connect the RPM sensor and thermocouple on its respective sockets, in the orientation that is shown in the colored labels on the fadec. If necessary, both leads can be extended using good quality servo extensions. Connect the throttle lead from the RX in its place, in the upper position. Side socket is ready for a second servo signal but not used on present firmware Airspeed (pitot) sensor, if used, must be connected as shown in the picture, at the side of the data terminal connection.
Using and Programming the FADEC: All the programming and measures are done trough the data terminal. Once the FADEC is programmed, it is not necessary its use and it is not recommendable to leave it inside the airplane to minimize the risk of interferences. The data terminal has a 16 character LCD screen and 4 buttons. The first two buttons on the left side allow moving trough the menus, and the two buttons on the right side allow changing the data.
Aligning the transmitter with the FADEC Turn on the transmitter and receiver. Using the menu up and (-) buttons move to the Radio menus. First screen will be this one: If you are sure that you want to modify the radio settings then press the right hand button (+) and the screen will change to: On your transmitter, raise first the trim to full and next the throttle stick to full. Ensure stick is firmly against the stop.
On rare occasions, usually when using a Futaba transmitter, it has been found that the throttle channel sense of movement may require reversing (Servo reverse) and repeat the transmitter alignment. Correct reading of throttle % by the FADEC can be verified in the second screen, percentage of the throttle position is shown on, 0% in the position of engine stop (trim and stick down), 100% with stick/trim full up and between 10% and 30% at idle.
The total running time of the engine in minutes (Tot), The time in seconds of the last engine run (Last) The total number of starts (cycles - CY). Use this screen to keep track of your total running time and starts. Battery used Counter. This screen display a mAh counter which shows the capacity used from the battery. The counter can be set to zero by pressing the (+) button.
the fadec only can reduce the throttle, it never will give more power than the one set by the pilot trough the throttle command. Second screen show the maximum airspeed reached on last flight in mph and km/h. This maximum is set to zero on next engine start. Setting the throttle to higher than 50% (with engine off) the second line will change to Current airspeed to allow you to test the operation of the airspeed sensor.
engine running the fadec will adjust the rotor speed accordingly the throttle position in a closed loop system. STOP speed: Set the minimum RPM that the engine is allowed to run. The FADEC will shutdown the engine if the rotor speed is below this setting. Start/Min temperature: Set the minimum temperature that the engine is allowed to run, and in manual start operation, sets the temperature from witch the pump begin to run. Maximum temperature: Set the maximum temperature that the engine is allowed to run.
START menus: On this submenu you will find the parameters used during the engine startup. Like the RUN menus, some of these parameters could be not available in fadecs used in production engines.
Manual mode: From values from 9 to 255 the power applied to the pump is fixed. It is necessary to test with the selected pump and battery the right value to have the pump to start at the desired speed. Pump Start ramp: This parameter adjust the speed of the fuel increase during the Fuel ramp phase. Higher values mean a faster fuel flow increase. Increase this value if the engine takes too long to arrive to idle, and decrease it if the starts are too hot, with the engine overshooting the idle speed.
2. When "Ready" is displayed, the user should cycle the stick to full power and back to idle. 3. When the stick is at idle again, the start sequence begins. 4. The glow-plug is powered and checked. Once hot, the starter is engaged at reduced power (soft start) and the gas valve is energized. If the glow test fail, a "Glow Bad" message is displayed, and if the starter fails to have the rotor turning a minimum RPM in 2 seconds, a start bad message is issued, and the autostart function aborted. 5.
Low Batt. Volts: During on start phase the fadec check the battery voltage, and abort the start if the voltage falls below this setting. Once the engine is running, the FADEC ignore this voltage and keep the engine running until the battery is fully depleted. Starter Power at Ignition: Sets the power applied to the starter during ignition phase.
Auto Start mode KERO: PLESE NOTE THAT: It is not easy to setup a kerostart system. Not a plug&play system. There are many variables to adjust, you must be an expert. Some engines are not compatible with kerostart due at combustion chamber or starter issues. It is very easy to convert an engine to a flamethrower. All tests must be done in a test bench equipped by fire suppressant devices.
problem, like a disconnected burner or an overload, the sequence will be aborted and a error message will be displayed. 3) Once the burner is at temperature, the starter is powered. First 2s the power is set fixed by the parameter "Starter power at ignition" to assure a good bendix engagement. After these 2 seconds, the starter power is regulated automatically to have the rotor turning at the RPM set by "Rpm at ignition".
RPM Fuel Ramp K . Set the rotor RPM where the fuel will be feed only to main injectors only and the burner switched off. Typical values 6.000-12.000 RPM Pump Start point Set the start power of the pump. Exactly same as gas start. Glow plug power Set the voltage of the burner Engine min.Flow: Set the percentage of time of the main fuel valve is open at beginning of the switchover phase.
During engine operation the FADEC measures and stores all the engine operating parameters recorded during the last the 51 minutes of operation. These measures can be downloaded later to a PC to study the behavior of the engine in flight and to diagnose any possible problems. Also, after each cycle of operation, the FADEC stores the last cause of shut down and the values of RPM, temperature and pump power at the moment of shutdown.
The user must provide an emergency shut-off (i.e. a servo operated cut-off valve) for increased security. Please read and follow the GTBA code of practice. (http://www.gtba.co.uk/codes/index.
