Mounting
4.1 Mounting of the carburetor
4.
After unpacking the engine must be completed according to the following instructions:
We screw the complete intake, including the carbu-
rettor, onto the engine using two M4 screws.
Do not forget the enclosed gasket which you insert
between the intake ange and the cylinder head.
Air intake is mounted on the carburettor, to which
we must ensure a sucient air supply for the
correct operation of the engine, do not cover it!
It is necessary to connect a hose with fuel supply to the carburettor. A protective plug is atta-
ched to the carburettor fuel tting due to dirt during transport. This plug must be removed
and the gas supply from the model‘s tank connected in its place.
When removing the engine from the model for a longer pe-
riod of time, it is necessary to replace the protective plug
to prevent the fuel in the carburetor from drying out.
Do not remove the air intake, do not modify it!
It‘s part of the engine, and the correct operation
of the engine depends on it.

After completing the installation of the carburetor, we can proceed to connect the waste output.
4.2 Waste output
It is necessary to drain a very small amount of unburned oil from the engine, which is used
to lubricate the crankcase. The nozzle, which is located on the engine block, is used for this
purpose. A cap is attached to this nozzle, which must be removed and replaced with a waste
oil hose, which will drain the oil out of the model.
We recommend leading the waste oil hose to the landing gear.
Waste output is very important and must never be blocked.
In any case do not reduce the diameter of the hose, or it will damage the engine.
If the waste output was clogged, the motor will be damaged.

4.3 Exhaust pipes
The third part that needs to be mounted is the exhaust pipe
The exhaust pipes are made so that they can be rotated around the axis. Therefore, set the
exhaust pipes to the desired position by turning and then secure by tightening the nut.
Beware of damage to the end of the pipe!
The end of the pipe serves as a sealing surface
for the extension tube. If damaged, it will not be
possible to seal the pipes correctly!
The diameter of the exhaust
pipe cannot be reduced!
ROTO extension pipe and exhaust not included!
There should be no more than 2mm
between the end of the exhaust pipe
and the exhaust.

4.4 The engine mount
4.5 Propeller installation
It is very important to mount the propeller correctly. 4 strength screws are used for this
purpose. Tighten them evenly! The propeller must be regularly checked and tightened,
especially when using a new wooden propeller.
For mounting the engine inside the model airplane,we recommend using
5mm high strength steel bolts, large at washers and lock nuts.

Direction of rotation of the propeller / Engine
Check the tightening of the propeller often, especially at beginning, when the
propeller is new!
Loose screws will cause the screws cuts to, exposing you to the risk of injury
as well as damage to your model. This danger is mainly posed by the use of a
wooden propeller.

Ignition5.
5.1 Ignition installation
Never remove the Hall sensors from the backplate.
5.2 Ignition power supply
The recommended power supply for ignition is 4-9V.
Always charge the batteries before ying.
Do not rely on charging from the last ight!
Ignition installation is an integral part of installing an engine in an aircraft.
Place the ignition in a suitable place where there is no risk of excessive heat from the
cylinder heads or the exhaust system.
If the ignition is heated above 60 °C, the ignition will switched off and the engine stops
working.
Make sure that the ignition is
well and suciently cooled!
Make sure that the connectors are
tted correctly and that there is no
risk of loosening them!
Do not bend the HV cables into sharp
bends, they may be interrupted!
Install the spark plug cup from the ignition to the spark plugs.
