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),

through the intake side of the engine, never trough the
exhaust.
If there is a fire, but the rotor remains free to spin and the starter is OK, raise the trim and 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.
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 menus and scroll the menus up to “Max
RPM”. Using the + and – buttons, you can change the rotor speed at full throttle. On engines
using ecus of version 7,42 or higher, on this screen is displayed, besides the full power RPM,
the equivalent thrust in Newton and in Lb. Please note that these figures are calculated
supposing an ambient temperature of 15ºC at sea level. Hotter ambient/higher altitude will
reduce the power output.
Autorestart function
All JetsMunt engines in production include the AUTORESTART function. This function can
quickly restart an engine automatically in Flight, but it should be understood that such a system
may cause damage to people and property. By default this function is disabled in the ecu, the
user should expressly enable it. By enabling this function, the user agrees that he/she has
understood the working principles and understands its limitations.
Restart options and how to enable them
Within the “Radio” menu, a new choice has been added to define the restart operation. The
ecu offers 3 choices:
·Standard operation
: After the shutdown the ecu should be reset (power cycled) to enable
another startup cycle. Engines are supplied in this mode from factory.
·Manual Start:
user can normally shutdown the ecu trough the transmitter (by lowering the
stick and trim). The ecu will execute the normal shutdown and post run cooling. Once the
cooling is finished (temperature below 100ºC), the ecu will return to power-up state, allowing
the engine to be restarted through the normal procedure (Trim-up, cycle stick). The time to
shut down and later start is exactly the same as standard operation. This mode is useful for
gliders, where the engine is used to climb to height, shutdown, soaring, restart, climb, etc. This
