New model consists of just two propellers, which allows  it to cover  twice as longer distanse in contrast with regular models. Enlarged longevity and small size  is appropriate for inspection of dangerous areas or making a search and rescue in destroyed building, for example.

The product has other advantages: 30 cm wide cowl, two props stacked one on top of the other, which can turn in opposite directions. That enhances drone’s efficiency compared to four-blade designs. The problem is in the point that  such craft has a tendency  to be unstable and difficult to handle.
