completely faulty design

Add to this that the orientation of the rotor blades on the picture is aerodynamically wrong. The direction of rotation as described in the manual clockwise can only be achieved in this wrong orientation. With proper alignment of the sheets to the wind turbine rotates exactly the other way around. And that in turn is wrong, the polarity of the generator and you would have to rewire cable to ever charge a battery can.

I'm very patient and hard to shock, but I am appalled that KOSMOS brings out something and it seems no one notices - oh dear ...

In addition, the procedure described that by wind power charged batteries used in other models function again as a driving battery can only if the entire wind turbine is disassembled works. Because there are not enough blocks to build wind turbine and other vehicles simultaneously.

Conclusion: useless!

Only the fun factor is to evaluate high: I have half died laughing when reading the instructions ;-)
