5.3.2 Engine installation
The MVVS116NP engine was used for the model prototype shown. You can use any engine (2-
cylinder boxer) size about 100-120 cc. The engine is mounted offset to the right 2.5 degrees,
horizontally at zero. It will probably always be necessary to mount the engine using spacers of
suitable length so that prop hub plane is about 2-3 mm in front of the engine cover plane and
respects the engine misalignment, ie the engine axis at the prop hub level intersects the vertical axis
of the model fuselage.
Silencers of any type can be placed on the engine, as often of the cup type, which are standardly
supplied with some engines (DLE, etc.), but better, due to the noise limits, by the silencer with
headers.
You can use the supplied 60 mm diameter muffler exhaust holder for this exhaust system.
The servo to control the carburetor should be placed under the engine using the Secraft side servo
mount - see the picture.
Place the engine ignition on the side sloping wall of the firewall.
