This is a simple propeller based flying toy. It has a motorized launcher. This toy helps makers to understand flying concept of toys, how propeller works, what angular bend of each blade gives better performance etc. When the toy is in rest, all the propeller blades are folded down. The launcher is nothing but a rotating pipe with a simple locking mechanism. When the propeller is place on the launcher and the motor is switched on, because of angular velocity the blades get starched. Locking mechanism allow the propeller to rotate fast. When it achieved high velocity, it lifts off .
