The “X45” engine is the result of a very extensive research and development programme by Gaspar Espiell & Xicoy Electronica SL supported by the latest fluid dynamics and analysis software to bring you an engine of unparalled performance and incredible response in an amazingly small package.
User Manual Version 1.0/2019 If you sell or pass on this engine to a 2 or subsequent owner please also pass on this User’s Manual or its link, so they can enjoy a safe and fulfilling ownership too. The Xicoy Electronica SL responsibility is limited exclusively to the repair of the engine and accessories which are outlined in the conditions of warranty.
User Manual Version 1.0/2019 Warranty The warranty duration for this Xicoy X45 engine is two years from date of completed purchase, or 25 running hours, whichever comes first. Warranty is valid solely for the original 1 owner and is non-transferable upon resale.
User Manual Version 1.0/2019 The engine and/or accessories show damage by physical contact with a corrosive substance through operation or storage. The engine has been used in 3D planes. Safety Notes Please remember that though this engine is very small and bijou it is most definitely NOT a toy and has the potential to hurt you or others around you if misused.
User Manual Version 1.0/2019 to clear the engine is to tip it forward and allow excess to escape through the front of the engine. Mop up with a rag. Tipping it backwards will not work as the internal construction of the engine prevents any liquid draining out to the rear.
User Manual Version 1.0/2019 leave a couple of cms of empty pipe where it connects to the engine to be sure you have not pushed a puddle of fuel into the engine which can cause a flame on start-up. The engine is happiest operating with the cable connector facing upwards and the fuel inlet below. But if it suits your installation better the engine can function safely in any orientation which suits your installation, but you will find starting is quickest and easiest with the recommended positioning.

User Manual Version 1.0/2019 To control the admission of fuel to the burner and main combustion chamber there are two miniature electric valves attached to a mounting block fitted to the front of the engine, under the cover. This block also holds the 4mm quick- release fuel feed connection.
User Manual Version 1.0/2019 Any air ducting to the engine inlet should have sufficient diameter of at least the engine case diameter (60mm / 2-1/2”). If an extended exhaust duct (internal tailpipe) for internal installation is required, it should be 45 to 50mm (1.8-2”) diameter and stiff enough to resist flattening in the airflow.

Menu Items . Users familiar with other Xicoy ECUs will notice the menu structure is very similar to previous generation ECUs, but with some display items in new positions, some extra functions added and some removed.

User Manual Version 1.0/2019 Connector board, the “Hub”. To enable connection of the power supply and signals to and from the outside world to the ECU, a small connector board which we call the “Hub” is provided. This forms the connecting point for: The receiver throttle signal (max voltage 10v) ...

User Manual Version 1.0/2019 for a neat and tidy installation. Never try to disassemble the pump, it has an extremely delicate internal structure and you will void its warranty. Operation: The difference between this pump and most others is that it also has its own tiny brushless 3-phase driver included within the pump housing.

User Manual Version 1.0/2019 ECU setup The ECU is contained on the engine. All the operating parameters relating to the starting and running of the engine are contained in its memory. All communications with the outside world occurs through the cable connected to the external Hub unit.

User Manual Version 1.0/2019 On some Futaba transmitters, it has been found that the throttle channel the sense of movement may require reversing (servo reverse) and to repeat the transmitter alignment. The setting up assumes the use of a transmitter (TX) with manual trims.
User Manual Version 1.0/2019 To program correctly the failsafe on your radio: 1) Adjust the travel of the throttle channel from -100% (stop position) to +100% (full power) 2) Adjust the ECU to your radio as described above. 3) Adjust the failsafe position of the throttle channel in your radio to -125%. If all is correctly adjusted, the ECU will stop the engine immediately when receive the “STOP”...
User Manual Version 1.0/2019 During startup It is recommended on a new installation, to initiate a start and then abort the 1 start after about 5 seconds. This ensures fuel has reached all part of the engine. The start can then be repeated and allowed to complete. During the start-up listen to the engine sound to check for positive sound of ignition, check looking from the exhaust that the kero is burning, or check for an increase in exhaust temperature in the display.
User Manual Version 1.0/2019 carefully and push the off button to stop as soon as fuel reaches close to the engine. Best too short than risk flood the engine. IMPORTANT: The prime procedure should be done only to fill the fuel tube and filter in the case of a first installation or in case of disassembling of the tubes.
User Manual Version 1.0/2019 WHAT TO DO IN THE CASE OF AN EMERGENCY During the start sequence the ECU will be in charge of everything, controlling temperature and RPM. The only thing the user can do is to abort the sequence by lowering the trim in the case that something abnormal (excessive flames in the exhaust, etc).

User Manual Version 1.0/2019 But it can also greatly increase the risk of fire, so before to enable this function, please read and understand the following: What the auto-restart function does: It automatically tries to restart the engine quickly and restore the power setting that is being asked by the transmitter.
User Manual Version 1.0/2019 In case you see the plane begins to stall or an uncontrolled landing is most likely, IMMEDIATELY set the trim and stick to STOP position to abort the restart function. A crash with the engine running normally ends with a fireball;...
User Manual Version 1.0/2019 LINEAR : Mean that the thrust develop linearly with the throttle setting. Could cause difficult taxi, as it would be difficult to fine adjust the power at low settings. HALF EXPO : An intermediate setting between the other two modes Stick Position MODE 0% (Idle)
User Manual Version 1.0/2019 short gap will cause extra pipe noise and depression inside the pipe, in extreme cases the exhaust tube can collapse due the low pressure inside (venture effect). Use in gliders and in 3D planes If you plan to use your engine in a glider, please consider to de-rate your engine. The typical use that is running at full power continuously for the entire flight in airframes that easily weight 4 times the engine thrust is very hard for the engine, as the internal elements like combustion chamber are subjected to maximum temperature and stress all the time, reducing the time between overhauls.
User Manual Version 1.0/2019 Low RPM: Engine had been shut down because the speed has fallen below the minimum. Usually lack of fuel (or an air bubble(s) has passed through the pump) HighTemp: Excessive temperature Battery!: battery voltage out of limits. Pump Overload: There is a restriction in the fuel path from the pump to the engine, or in the engine itself.
