Function:
This product is designed for use in a living or family room. Allow a minimum of three meters of clear space around yourself in all directions.
As you gain experience ,you should still practice keeping a safe area.
When hovering up to 30cm above the ground, the helicopter is affected by its own rotor wash, and becomes unsteady. This is referred to as "ground effect", and while it has the benefit of facilitating lift.
If you find it difficult to fly close to the ground, abandon this mode and fly the helicopter at knee-height. A stable and easy-to-fly helicopter ensures a sensation of reality in flight.
Slowly raise the throttle stick until the helicopter is 30~50cm high and hold it there.
Slowly tilt the stick in the direction you want to move the unit.
Practice, one at a time and in order, the operation of the rudder, elevator, and aileron.
