The launcher is a light frame (10) and has a front and back ring (11,12) to which a carriage that slides on the line is hooked. The part with the front ring (12) is bent to release the launcher and model from the carriage. The model is held on two safety hooks (13,14) under the launcher. A sail (15) propels the launcher and has a slot (16) that the line passes through.
