I see that this wonderful aircraft is very similar in purpose and characteristics of the airplane with Savage.
Currently completed certification work in Germany for our saber propeller diameter of 1820 and 1840 mm (71 and 72") on this plane.
In this regard, German, Italian and Czech pilots had put the propeller on its planes.
And it all started with the fact that an Italian pilot took a chance and ordered the propeller (71") for your Savage this fall.
It was his propeller went to the test.
It seems that he was not mistaken, because orders for several pieces for his friends.
Static thrust amounted to 260 kg per 5600 rev/min (15 C, 1020 hpa at an elevation of 614 m).
In addition, to obtain a very low noise level in comparison with the two-bladed propellers.
