This four-part set represents the exhausts and exhaust shrouds of the Packard V-1650 Merlin-powered P-51 Mustang fighter of World War Two and later, specifically the P-51B, P-51C, P-51D and P-51K. The V-1650 was a Rolls Royce Merlin engine license-built in the United States by Packard Motor Car Company.
Packard-built Merlins were also fit to the P-51H Mustang, P-63 King Cobra, and P-40F Warhawk. Packard V-1650 engines were fit to many DeHavilland Mosquito and Avro Lancasters built in Canada.
These parts are an original 3D design based on authoritative 2D references and measurements made from a surviving Packard-bult V-1650-7 Merlin engine and scans of original North American Aviation blueprints available through AirCorpsLibrary.com. The Packard V-1650-7 was the common powerplant of the P-51D and P-51K Mustang (Mustang Mk.IV and CA-18 Mk.21).
The models are not 3D-printed copies of any RC model kit's parts. Therefore, they may be sized, shaped and detailed differently than the parts in your RC kit. Depending on which kit you have, some adjustment to your kit's parts may be needed for best fit.
These parts are left- and right-handed. When installing your parts, position them so the side with the wider-spaced nuts is down.

Notice: this set is available in different materials including "Fine Detail Plastic", which is an acrylic plastic chemically related to Plexiglas, and the more economical "Natural Versatile Plastic", a kind of nylon. White or black "Natural Versatile Plastic" are waterproof and strong, a good choice for models where durability is important.
Sharp edges of models printed in white or black "Natural Versatile Plastic" appear less defined and more rounded. Being nylon, "Natural Versatile Plastic" is generally not sandable and fewer types of paint and glue will adhere to it. Care is recommended in choosing a paint that will adhere to, and fully cure upon, nylon. Google "glue for nylon", "paint for nylon" and "primer for nylon" to find several good choices.
Customers report that white or black "Natural Versatile Plastic" will have noticeable striations (print lines). To help smooth "Natural Versatile Plastic" surfaces, apply thin layers of primer meant specifically for nylon. Allow the primer to harden. Then smooth the hardened primer.
