Adjusting the engine maximum power.
The engine comes from factory adjusted for its maximum thrust. But it is possible to reduce the
maximum power if necessary. To do so, go to RUN menu and scroll the menus up to "Max RPM".
Using the + and – buttons, you can change the engine speed at full throttle. Beside the full power
RPM, the equivalent thrust in Newton and in Lb. Please note that these figures are calculated
based on an ambient temperature of 15ºC at sea level. Hotter ambient/higher altitude will reduce
the power output. You can make the adjustment while the engine is running to see the effect but
be aware the new setting will take a little time to settle.
Engine shut down procedure
To shut down the engine lower the trim and the stick. It is recommendable that before shutting
down the engine to restrain the model and then raise the throttle stick to approximately 25%, al-
lowing temperatures to stabilize for around 5 seconds before carrying out the shutdown procedure.
After the shutdown the ECU will keep the starting motor running to cool the engine under 100ºc. A
special feature on this system is that the power of the receiver can be switched off before the
cooling procedure is complete. The ECU will shut down itself when the procedure is complete.
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, grinding noise, etc).
If a problem is detected, first: Move the trim to the low position to abort the sequence. If there
is a fire in the engine and the problem is because the starter has failed or the engine is seized (not
turning), IMMEDIATELY APPLY THE FIRE EXTINGUISHER through the intake side of the
engine, never through the exhaust.
If there is a fire, but the engine rotor remains free to spin and the starter is OK, raise the stick to
the full power position for 3 seconds, this will connect the starter manually to ventilate the engine
and extinguish the fire. The throttle channel acts as a starter switch. Be sure to lower the trim with
the stick to avoid triggering another start.
Autorestart function
All X Series engines include the AUTORESTART function. This function can quickly restart an en-
gine automatically, but it should be understood that such a system may cause damage to people
and property if triggered inappropriately. By default this function is disabled in the ECU, the user
should expressly enable it. By enabling this function, the user agrees that he have understood the
working principles and understands its limitations.
Restart options and how to enable them:
Within the "Radio" menu, a selection defines the restart operation.
The ECU offers 3 choices:
Standard operation (off): After the shutdown the ECU
should be reset (power cycled off then on) to enable another start-up
cycle. Engines are supplied in this mode from factory.
