3.5 Occupant restraint Harness
Both front and rear seats are fitted with a restraint harness system.
When flying the trike solo it is important to fasten the rear seat belt to prevent contact with hot engine
components in flight.

with a gearbox, which delivers smooth thrust via a reduction drive. This power unit is complemented with a ground
adjustable propeller giving the ultimate in performance and reliability. The engine is fitted with Bing carburettors
with an external dry filter.
3.7 Propeller
Manufacturer: Aerolux
Model: _AL-C3L
Type: 3 Blade Composite ground adjustable
Diameter: 1750mm
Pitch:
The maximum propeller speed occurs when the engine RPM reaches 5800 RPM.
The propeller pitch is set at 14 deg. . Settings outside this specification have an unknown effect on the Ultralight
performance, and are not approved.
3.8 Manifold air heating system
The system is designed for:
-minimizing risk of carburetor icing;
- manifold pressure noise reduction;
- manifold pressure equalizing.
The working medium in the system is intake air which warms up from the exhaust pipe and transfers to the
manifold receiver by manifold pipes.
The manifold receiver is attached directly to the carburetor and has two flap valves which are connected to the
control arm. The control arm of the receiver has two positions:
- flap valves are open;
- flap valves are closed.
Open flap valves enable the warm intake air to supply into the carburetor.
Closed flap valves restrict the warm air intake and open the ambient air to supply into the carburetor.
Control switch is mounted on the right side of the cockpit(Aeros-2 trike) or on the central part of the dash(Cross
Country trike).
