The launching platform is attached to the back of a hand with velcro. One of the two propellers is placed on the platform. Then you pull the string, which will cause the propeller to gain speed and take off. Ideal to involve the second hand in an activity, even if the hand function is limited.
The propeller is easy to catch and can fly up to 6 meters high.
This handcopter guarantees lots of fun. Can be used both outside and inside.
