The Sinus motorglider is a strutless 14.97 m (49' 1½") wing span motorglider. It is normally powered by the Rotax 912 4-stroke 80 hp engine or the Rotax 503 2-stroke engine.
The Sinus is equipped with positive and negative flaperons, airbrakes and tail wheel (optional nosewheel). It is manufactured from hi-tech epoxy resin, fibreglass, carbon and kevlar composites. The airfoil used on the wings is IMD 029-b (Orlando, Venuti).
The cabin is properly insulated from noise and very comfortable for even those long flights. The seats are ergonomic with an adjustable head rest. Both the pilot and passenger pedals have differential toe brakes fitted. The pedals are adjustable forward and aft in flight and are manufactured from stainless steel. All controls are easy to use and reach from both seats. Pedals and sticks are dual. The wing tanks have the fuel cap on top, as well as a visual check within the cockpit for the fuel level. The standard capacity is 60 liters with a long range option increasing the capacity to around 100 litres.
The main landing gear is aerodynamically profiled and made of composite materials. The main wheels have strong hydraulic disk brakes and the tail wheel or nosewheel option is directly controlled by the pedals. The airbrakes on top of the wing allow landing the Sinus in very short distances over high obstacles.
The Sinus assembly is very simple, just like conventional gliders, and the wing control connections are automatically locked on connection of the wings. It takes most owners about 20 minutes to rig or de-rig the aircraft.
The Sinus 503 is our entry level aircraft. It is reasonably priced, some would say cheap, and is light and comfortable to fly. The Sinus 503 is powered by the Rotax 50 hp, air-cooled, two stroke engine and even as our basic aircraft it comes complete with all engine and flight instruments, cabin heaters and all the other options described in the price list. The Sinus 503 may be cheap in price but it isn't lacking in features. I would highly recommend the Sinus 503 as a thermalling and soaring aircraft. Whilst it has the ability to tour under engine, it is not as suitable for Australia as the Sinus 912.
The Sinus 912 is our most popular aircraft. It uses the legendary Rotax 912 80 hp 4 cylinder 4-stroke engine and it allows the Sinus to become a 'super sophisticated' motorglider just like the 'real ones' but at a 1/3 of the price. If you want to spoil yourself and your passenger, the Rotax 912 is the engine of choice for the vast distances we travel in Australia.
