M730 Chaparral anti-aircraft missile system

The M730 Chaparral missile system was a self-propelled short-ranged SAM system, employing a missile based on the Raytheon AIM-9 Sidewinder short-range air-to-air missile. The system was developed in 1967. It was comprised of four basic components; the MIM-72 Chaparral missile, the M54 launcher, and the M730 vehicle that carries them. Collectively, these were also referred to as the M48 fire unit. A detailed description can be found at http://www.military-today.com/missiles/m48_chaparral.htm, and it can be seen ‘in action’ at https://www.youtube.com/watch?v=zk3cxSbahgk.

Two models are provided in this product, one showing the unit with blast shields raised and ready for action, and a second that portrays it ready to move. The design has been split into several parts for ease of printing, and to provide a more versatile platform. The basic carrier is provided in two versions as indicated above, and they share the same wheel/track assemblies. Each version has two models, one with and one without the front winch, to reflect the different iterations of the vehicle. The sled that carries the launcher assembly is a separate part that drops into the load bed on the carrier. Two launcher assemblies are provided, one in firing position, and one in the retracted travel position. The missile is provided as a separate part, and is normally not carried on the launcher when it is travelling. The hoops that are carried on the front of the vehicle are modelled separately, as it was found that they caused issues with removal of supports. A photograph of a vehicle in Iraq indicated a local modification to carry jerrycans and other stowage on the front, where a shelf has been added. This is modelled as an optional part for use with the winch-less versions.

The ‘sled’ that carries the turret was missing in the main zip file, and has now been added as a separate zip file.

The product is offered for personal, non-commercial use. Derivative designs for personal use may be generated, but neither the original nor derivatives may be shared with others. Attribution of the design is requested should printed models be exhibited or otherwise shared. Models printed from this design or derivatives may not be sold commercially.

I have had some comments about excessive complexity in the hull, and some difficulties in printing the missiles because of thin wings. I have now provided files to tackle both issues, with apologies for any inconvenience caused. I have also provided versions of the turret and hull with holes for magnets if desired.
