Новые моторы от известной Итальянской конторы
NOVAROSSI has made a complete new .57 helicopter engine for their REX line.
The R57HR 3D is specially made for the 3D Helicopter competition market.
Developed to meet the highest demands of todays 3D competition pilots.
The strongest point of the R57HR 3D is not purely its maximum power output but mainly the power distribution throughout the RPM range.
Great engine dynamics, simple to tune and its fatique resistence where other important development goals of the NOVAROSSI WORLD R&D team.
Inside the R57HR 3D you find an optimized combination of the Piston/conrod and crankshaft to improve the engine performance and at the same time reducing vibrations.
While the sleeve of the R57HR 3D has 5 transfer ports, the R91HR 3D has 8.
This difference is due to different fuel mixture dynamics inside the two engines, in short: improved efficiency.
To tune the R57HR 3D and the R91HR 3D as simple as possible, without compromizing engine dynamics NOVAROSSI WORLD created a new carburettor for the R57HR 3D and R91HR 3D.
The carburettor features 2 needles to regulate the fuel flow at low/high speed.
To minimise the heat transfer from the crankcase into the carburettor we have mounted two (2) rubber O-Rings to insulate the carburettor.
Моторчики кушают топливо с содержанием нитры 20-30 процентов.
