Toy military helicopter with inertia and e-battle sound, PVC box

2 toy military helicopters, one yellow, the other green. The yellow helicopter is modeled as a vehicle and has wheels to move on flat surfaces. The green helicopter has a more militarized look, as is typical of shooting toys. It has rackets attached to its wings and spinning propellers. Both helicopters are equipped with inertial and electric motors. They can work both in autonomous mode, with inertia, and at the expense of the battery, providing sound and light effects.
