Aircraft and systems on board
Sinus is a 15-meter-wingspan, two-seat T-tail
motorglider made almost entirely of compos-
ite materials. Its low-drag, high-wing-mono-
plane, engine-at-the-front construction makes
it a perfect glider when ying unpowered. In
fact, the propeller can be feathered to reduce
drag even more.
The undercarriage is a taildragger type with
two main, brake equipped, wheels mounted
on struts and a free-spinning or rudder-guided
tail wheel.
Sinus features aperons, interconnected aps
and ailerons presented in the same deecting
surface. Flaps oer 4 settings: neutral, 1
st
, 2
nd
and the negative position of which none have
any impact on aileron deections whatsoever.
What is more, individual main ight control
levers make Sinus ideal for initial as well as for
advanced ight training. All aileron, elevator
and ap controls are connected to the cabin
controls using self-tting push-pull tubes.
Rudder deects via cables. The elevator trim is
mechanical, spring type.
All aircrafts ship with H type safety harness
attached to the fuselage at three mounting
points. Rudder and belonging brake pedals
can be adjusted to suit your size and needs.
Fuel tanks are located inside the wings. Fuel
selector is in the form of two separate valves,
located on the left and right upper wall of the
cabin. Fuel hose connectors are self securing
- this prevents fuel spills when disassembling
the aircraft. The gascolator is located beneath
the lower engine cover. Refuelling can be done
by pouring fuel through the reservoir openings
on top of the wings or by using an electrical
fuel pump instead. Also featured are low-fuel
signal lights on the instrument panel.
All glass surfaces are made of 2 mm anti UV GE
Lexan, which was specially developed not to
shatter or split on impact.
Main wheel brakes are drum or disc, wire
driven (old type) or hydraulic type (new type).
The hydraulic brake uid used is DOT 3 or DOT
4. Cabin ventilation is achieved through special
ducts tted onto glass doors, cabin heating,
however, is provided utilizing of hot air from
the engine.
To enhance aerodynamics even more, every
Sinus ultralight motorglider comes equipped
with special wheel fairings and the propeller
spinner. Standard propeller is BAM2, used, test-
ed and certied beforehand on other Pipistrel
aircraft. The VARIO propeller, oering in-ight
variable pitch and feathering is and option.
Electric circuit enables the pilot to test individ-
ual circuit items and to disconnect the entire
wiring but leave the engine running, should
there come to a distress situation. Navigational
(NAV), anti collision (AC) and landing (LDG)
lights are an option. The rewall is enforced by
heat and noise insulation.
Basic instruments come installed with opera-
tional limits pre-designated. Also, signal lights
indicating danger zones are provided.
Parachute rescue system is an option.
