Now I finish adjustment 4Х4. In the near future I fly in the street. Very interesting variant. The big load-carrying capacity also is expected the big stability.
But at options there are minor problems.
Approximately here the such.... The Big turbulence in the closed space... Lifts very strong wind. Capacity very big.
In this scheme (4X4) it is established eight usual ESC. Further will be established ESC-4А and two ESC X450. It seems to me that in the second case flight much more will improve. ESC X450 will soon come, therefore the basic rate on them.
