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” signal (-100%), but if the
signal received is Failsafe (-125%) the ECU will set Idle power during 2 seconds, and, if after these 2 seconds the
Failsafe condition persists, will shut down the engine.
Once you have the radio programmed, check it by setting the throttle to any position, then switching off the
transmitter; after two seconds the “failsafe” reading should be displayed.
There are many more parameters that can be modified in the ECU, but we have specifically programmed your ECU
with the optimum settings and allowed access only to those needed.
Further adjustment should not be required and can only be carried out by Xicoy Electronica SL or your authorized
dealer or service agent.
Preparing the engine for running
A suitable test stand should be made to hold the engine. A pair of sturdy timber rails securely fixed to a base board
will suffice. Use screws to hold together, don´t rely on a nailed assembly. The engine can be secured to the rails using
good quality woodscrews. Use at least 20mm/3/4” long to be sure the engine is properly secure.
A platform/table/workbench is required to clamp or fix the test stand onto. Make sure this can be easily transported
outside and weight enough to ensure it cannot be blown over by the thrust of the engine. Set up the fuel tank, fuel
pump, battery and display onto the baseboard, ideally secured. Nothing should be fixed downstream of the engine.
Select a clear area for running – keep clear of areas with loose leaves, sand or other debris that could be picked up or
drawn towards the intake. Ensure the fuel tank is position well clear of the exhaust area and secured. You and your
helper and any spectators should stand at the front of the engine, not to the side.
Important notes for kerostart engines:
PLEASE READ
The kerostart system used on this engine is a reliable and well tested system that produces very smooth and trouble
free starts. However, extra care and attention must be paid when starting a kerostart engine.
The main difference between gas and kerosene is that in the case of a failed ignition, the gas dissipates quickly in the
air and won't stay inside the engine. Kerosene (or diesel) is liquid and if unburned, will pool inside the engine and stay
there forever. The engine can hold a big quantity of kerosene inside. This kerosene will be ignited on next successful
start-up and will be pushed to the exhaust as soon as the airflow inside the engine is sufficient, then it will be ignited
in the exhaust, causing a hot start (in extreme cases a big fireball) that surely will not hurt the engine, but can destroy
the model.
