User Manual X45 Version 1.0/2019Copyright © 2019 by Xicoy Electrònica S.L. All rights reserved Page 1110. Any air ducting to the engine inlet should have sufficient diameter of at least the engine case diameter (60mm/ 2-1/2”).11. 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. Leave a gap of 25mm (1”) from tip of the exhaustto the end of the duct (excluding bell mouth length).12. Extreme care should be taken to avoid the possibility of foreign objects, loose parts or debris being allowed toenter the compartment where the engine is installed. Always use the supplied FOD screen but regard this as a last lineof defence and not as a reason not to practice good housekeeping. Before filling the tank and starting the engine forthe first time, turn the model upside down and give it a good shake to loosen and clear any small bits and pieces lyingin the engine compartment. A go-around with the hoover is also a good idea.13. We recommend testing the engine on a test stand prior to fitting to an airframe.14. You should have a clear idea how to arrange all the components needed to run the engine inside the model.The main issues are fuel tank (locate centre of tank to CofG), bubble trap position (if used), locating the fuel pump inclose proximity to the source of the fuel (bubble trap or tank) and adjusting the receiver and ECU batteries to achieveoptimum location for balancing the model.15. Do not under any circumstances try to run the fuel pump by plugging it into any other FADEC brushless pumpcontrol or similar type 3-phase driver. It does not work like that and you will destroy it in the process.Component DescriptionECU (Engine Control Unit)The ECU and indeed the whole system used on this engine are totally new and unlike any previous version of XicoyECU. It is a new controller developed specifically for this application by Xicoy Electronica which is in the form of asmall C-shaped pcb fitted under the front cover of the engine. It is connected via the 3-wire cable which plugs into theengine and to a small connector board called the “Hub” externally. The three wires are just plus (+) minus (–) anddata. The signals in and out of the ECU are via bidirectional digital data link, no direct connection to the outside worldis required, or possible.The ECU is a powerful new design using a completely new architecture than used before, so represents not anupgraded version of anything before but a new system completely. This new platform allows us to break from thelimitations of older technologies to make use of the latest high speed connectivity to add many more functions thanwere possible before, and all using a single wire data cable. All signals in and out of the ECU go via the Hub which actsas a clearing house for ECU data and the outside world.The ECU is programmed specifically for the X45 with the engine operating characteristics, start parameters, throttlecurves and operating routines. Some of these are user settable like the radio setup and maximum thrust settingswhich are accessed used via a menu system on a special data display which plugs into the Hub. A version of the Hubwill be available with a display built in and with adjuster buttons which you can mount in your model, to eliminate |
