The invention relates to a holding and starting device for hydro-pneumatically driven aircrafts, in particular model rockets, composed of a base body carrying a flange that can be connected to it, the flange furthermore merging into a hollow cylinder portion receiving at least one sealing ring arranged at the outer circumference side, latches pivotable about a shaft, located on the flange and laterally encompassing the hollow cylinder portion, and having a latch engagement means for a locking ring of the aircraft, a release ring rotatably mounted on the base body relative to the longitudinal axis of the hollow cylinder portion and having recesses or setoffs for receiving stop ends of the respective latch, so that a release of the locking ring of the aircraft can take place. According to the invention, the latches have an actuating surface between the point of rotation of the shaft and the latch engagement means, which surface causes a pivoting movement of the latches when a nozzle-like neck portion of the aircraft is put on, with the consequence, that the respective latch engagement means engage behind the locking ring, furthermore the release ring is pretensioned in one of its rotational directions by means of an energy accumulator, wherein with a pivoting movement of the latches with their respective latch engagement means toward the locking ring, the stop ends of the latches are subjected to a positional change and exit the respective recess or the respective setoff such that the release ring turns into a holding end position. With or at a rotation of the release ring against the pretension, the stop ends of the latches move into the respective associated setoff or the respective associated recess, so that the latches release the locking ring for starting, wherein the latches are in this respect subjected to a pretension in the area between the point of rotation of the shaft and the stop end toward the center or middle point of the release ring.

A disc launching device includes a long handle and a disc holder at one end of the handle. The handle may include a grip end for holding the handle, an attachment end opposite the grip end, and a shaft extending from the grip end to the attachment end. The disc holder is attached to the attachment end of the handle. It includes a front rail for holding one side of a disc, a back rail for holding an opposite side of the disc, and at least one support member extending between the front rail and the back rail. The front rail and the back rail form an opening on one side of the disc holder, configured to allow the disc to launch out of the disc holder through the opening when sufficient forward momentum is applied to the disc holder via the handle.

Systems and methods for a toy rocket launch platform safety system are provided. Various embodiments include a system of switches attached to a moveable launch platform coupled to a static support structure via a pivot mechanism. The system of switches open when the moveable launch platform is not level to the ground or aligned along the central axis of the static support structure. When the system of switches is open, a toy rocket launch cannot occur. Some embodiments include a launch guidance system attached to the launch platform. A toy rocket is coupled to the launch guidance structure in such a way that the toy rocket assumes a trajectory dictated by the launch guidance structure. The launch guidance structure may be collapsible and when fully extended, achieves a height greater than that of the average adult.

A self-propelled rocket toy includes an elongated body located along a longitudinal axis having a top end opposite a bottom end. The body may include at least two supports outwardly extending from and fixed relative to the body. A propeller is centered about the longitudinal axis located about the body's bottom end. An electric motor is disposed within the body and mechanically coupled to the propeller. A power source is disposed within the body and electrically coupled to the electric motor. An activation mechanism is electrically coupled to the electric motor and power source. The activation mechanism may be a launch button or a centrifugal switch. The at least two supports are fins extending outwardly and are configured to induce an autorotation for a controlled descent, either by their shape and design and/or by including a pivotably attached flap.
