INSTALLING THE ENGINE
For proper mounting, we suggest and recommend you to suspend flexibly the drive
train in the following ways:
• Mounting the engine straight (with
spark plug facing up): usually 4 silent-blocks
are enough (our code A22) and they can be installed on the edge of the possible
engine mounts between the engine itself and the aircraft frame . We dispose of an
Ergal support, complete with silent-blocks that extremely reduces the transmission
of vibrations to the aircraft frame (our code A50/A).
• Mounting the engine upside down (with
spark plug down): please follow the same
instructions as the above case. We always recommend the use of the Ergal support,
complete with silent-blocks that extremely reduces the transmission of vibrations to
the aircraft frame.
• Our water pump has a
particular vent-hole, closed by a 6 Allen screw or by an
hexagonal-head cup (key 13) , that is used to remove air from the circuit. Without
this purge, it might create an air bubble that would prevent the normal circulation of
coolant.
• Installation of the
exhaust system: the exhaust system provided with our engines
is the result of years of research and experimentation. To maintain the standard of
performance and to have a long life, we recommend elastically suspend the system
using correct silent-blocks.
The ball-joint on the exhaust manifold, while assembling, must be lubricated with
copper-based grease which can resist at high temperature (800°C).
• For reasons of your own and others' safety,
we suggest you to wire exhaust
springs to prevent that in case of break, hitting the propeller, they could become
bullets.
ELECTRIC SYSTEM
Information usable for all our engines: the motor must be earthed by connecting the
aircraft frame by a copper wire. Otherwise you can damage the ignition and some
engine components.
The ground must be connected to the starter motor housing support and an
additional one between the crankcase and the support of the engine itself.
If necessary, check the operation of the mass by its specific instrument, that should
indicate a resistance value equal to zero. This operation must be done among the
