Old ideas in new study:
This gear drive in a helicopter that is bothering me. Another way to get rid of her. By the way, turned out that the rear propeller and also you can get rid of , because the helicopter does not have the torque of the main propeller.
The helicopter had already been built. But it had drawbacks: no, for example, could not take full advantage of autorotation, because the propeller with a hole through the center did not have good aerodynamic properties....

I missed this problem and the propeller is as it is most optimal.
Also today after assuming control of the helicopter adjustable nozzle (vectoring nozzle) on the outlet gases from the turbine driven, will be very precise.

In summary the lack of a gear transmission and rear propeller helicopter will certainly reduce weight.
