2Installation instructions
2.1Mounting and securing the engine
The F30E engine has twelve securing points with threads (M10) that can be used for securing the engine.
There are in each case four screw threads on the underside, on the left and the right housing side of the
engine.
The engine should be secured in such a way that the force transferred from the engine to the suspension can
be absorbed as widely as possible. Suspension absorption should also be made as hard as possible, since the
engine can become unstable if absorption is too soft. This leads to problems for the carburation (frothing of
fuel, uncontrolled vibration of the fuel pump diaphragm) and thus to an unsafe operation of the engine.
-Suggestion for securing the engine:
The engine is screwed to a fastening plate that is about twice as wide as the underside of the engine (the
wider the better). On the two outer surfaces of the fastening plate six (or more) hard rubber absorber
elements (three on each side) are attached in an axial direction. This complete substructure is secured by the
rubber absorber elements on to a corresponding base plate that is firmly connected to the device.
2.2The engine?s air supply
The engine must be installed so the cooling air stream fed to the engine is sufficient to ensure the engine is
cooled and that air is also supplied to the carburettors.
With an enclosed installation it is important that the hot outlet air stream is not fed to the carburettors, as this
leads to a drastic reduction in performance. It is also important to ensure that the hot outlet airstream can
escape with out hindrance from the metal cladding, since this leads to overheating of the engine and also
damage.
The ducted cooling system fixed to the motor is designed so that adequate supply of fresh air for cooling of
the engine is sufficient. Changes to the cooling system therefore are not recommended. It is essential to
ensure that a sufficient supply of air is provided at all times during operation.
2.3Fuel Injection Electrical installation:
The 12 Volt power supply has to be connected separate, which means between the battery and the
computer there cannot be any other electrical components (consumer) connected to it.
The wire harness is to be installed in a way where the electrical cable cannot touch any ground
during operation.
The cable has to be installed in such a way that no chance of wear or breakage could occur.
The control unit must not be exposed to water. All other electrical components are waterproof.
The control unit has to be installed in an area where the air pressure sensor (nipple protruding from
side of computer) cannot be influenced by turbulent air.
This air pressure connector cannot be sealed off (rubber caps etc.).
The electrical components cannot exceed an operation temperature of 80 degree Celsius, 176 degree
Fahrenheit. (Short time maximum exposure of 100C, 212F).
The wire harness has to be installed with a sufficient enough distance from all other electrical wires
to prevent electromagnetic interference of the sensor and computer wires of the injection system.
The required wire diagram and applicable fuses are shown in the circuit diagram on page 35.
2.4Hydraulic Installation:
The maximum suction height for the electric fuel pump is 500mm or 19 inches. (Also pay close
attention to extreme flying position ie. take off).
The fuel pump should be installed close by the fuel tank, so the suction pipe stays short. The supply
has to be dimensional where the fuel pump can suck in a minimum of 120 L/H. (Recommended pipe
diameter minimum 10mm or 0.39 inches).
