3.3.7 Power-Plant Controls and Instruments
Power and choke are controlled via bowden cables led from the carburettors over the engine to the central
console in the cockpit. Operation from the cockpit is realised by means of a lever with adjustable friction.
The cowl flaps are moved simultaneously with the lever for opening and closing the propeller dome.
The power-plant instruments are located on the right face of the instrument panel.
3.3.8 Fire Protection
To the front, upwards and rearwards, the engine including the exhaust system and the induction system
(except for induction system screens) is separated by means of a fire-wall from the remaining parts of the
powered sailplane. The firewall is made of corrosion resistant steel sheet of .01 in. (0,38 mm) thickness.
The engine compartment is enclosed at the sides and below by the engine cowlings. The internal surfaces of
the cowlings are treated with a fire protection coating.
3.3.9 Engine Cowlings
The engine cowling is formed by the lateral and the lower parts of the central fuselage cowling. The cowlings
are connected to each other and to the fuselage front section and to the tail boom by means of Camloc snap
fasteners.
3.3.10 Propeller
The articulated propeller consists of a central part and two propeller blades hinged to this central part. The
articulation axle is aligned so that the propeller blades are movable in the plane of rotation of the propeller.
When the propeller is not running, the blades are folded inwards by means of springs.
When the engine is started, the blades unfold automatically by centrifugal force. Soft rubber stops protect the
blades in case of probable overswing. Also during folding, the movement of the blades is cushioned by
rubber stops.
The central part of the propeller is made of high strength aluminium. The propeller blades are made of
carbon/aramide/glass laminate. The blade hinges are equipped with needle bearings.
Marking:

3.3.11 Drive train System
The drivetrain includes:
− Clutch on the engine side: a force transmitting clutch operated by direction and speed. In addition, the
clutch has integrated positive elements to allow torsional and angular flexibility as well as longitudinal
flexibility. Since the clutch transmits the torque by friction, it serves as an overload protection at the same
time.
