To provide a system to create a new simple helicopter-like bamboo toy by giving continuous revolving energy to a usual simple helicopter-like bamboo toy.

A system of the simple helicopter-like bamboo toy is that an upper propeller 2 is installed at an upper end of a body 1, a lower propeller 5 which is an angle of anti-elevation to an upper part of the body is fixed to a little lower part of the upper part of the body and both propellers 2, 5 are spun in the opposite direction to each other by a power rubber in the body 1 Thereby, a flight game (an altitude of climb, the duration of flight and a flight posture) and a design and manufacture can be amused as a new simple helicopter-like bamboo toy which is given power to a usual simple helicopter like bamboo toy.
