Good to know , in many cases those who invent first
are anonymous.
However let's go on making toys , maby one day we will get a flying saucer.

This is even more cool than the micro RC cars that came out a few years
ago (not much bigger than 'matchbox/hotwheel' cars).
The double propellers is actually not that new, but genius nonetheless.
Before Igor Sikorsky created the first 'practical' helicopter (contrary to
popular belief he did not INVENT the helicopter), there were many
different ideas tried to keep the machine from rotating and the double
blade was one of them. It worked, but was very complicated mechanically
(There are actually a few full size helicopters that work this way even
now). Sikorsky realized that the rear stabilizer propeller (the 'tail
blade') was not the perfect solution, but it was the best solution from a
practical standpoint.
It's ironic that the more complex counter-rotation problem is finally
solved in a toy.
