If an extended exhaust duct (internal tailpipe) for internal installation is required, it should
be diameter as shown in the Specifications, and stiff enough to resist flattening in the airflow.
Leave a gap of 25mm (1”) from tip of the exhaust to the end of the duct (excluding bell mouth
length).

Extreme care should be taken to avoid the possibility of foreign objects, loose parts, dust or
debris being allowed to enter the compartment where the engine is installed. Always use the sup-
plied FOD screen but regard this as a last line of defence and not as a reason not to practice good
housekeeping. Before filling the tank and starting the engine for the first time, turn the model up-
side down and give it a good shake to loosen and clear any small bits and pieces lying in the en-
gine compartment. A go-around with the hoover is also a good idea.

We recommend testing the engine on a test stand prior to fitting to an airframe.

You should have a clear idea how to arrange all the components needed to run the engine
inside the model. The main issues are fuel tank (locate centre of tank to CofG), bubble trap posi-
tion (if used), locating the fuel pump in close proximity to the source of the fuel (bubble trap or
tank) and adjusting the receiver and ECU batteries to achieve optimum location for balancing the
model.

Do not
under any circumstances try to run the fuel pump by plugging it into any other
FADEC brushless pump control or similar type 3-phase driver. It does not work like that and you
will destroy it in the process.

If you have two models you want to use the engine for, purchase a 2
nd
Installation Kit and
install all the components, pump, filter etc, as if it were a new install. You then only need to swap
the engine over between the models and the remaining installation is not disturbed, which gives
the greatest flight security. The engine can accommodate any slight changes due to the installa-
tion. Don´t forget to blank off and cover the end of the fuel feed pipe to keep it clean.
