Precision Objects
Precision Objects · Handcrafted in Miami
Each Aero Mecanique R9 passes through nearly fifty hours of studio work — production, multi-stage hand-painting, controlled curing, individual assembly, and final inspection. There is no production line. Every unit is built one at a time at our Miami atelier.
The result is a precision object — a 9-cylinder radial engine arranged in star configuration, finished with copper-toned connecting links, brass-toned hub and propeller hardware, set on a carbon-textured composite base. Hoffmann Atelier produces, finishes, numbers, and certifies every unit personally.
The Aero Mecanique R9 — essentials
The full Hoffmann Atelier experience
Both editions share the same hand-finished precision object, the same numbered certificate, the same signed welcome letter, and the same technical blueprint. The Collector's Edition adds the premium archival display box and white-glove delivery. Limited to 100 total units across both editions.
Every unit receives a multi-coat hand-painted finish, individually cured and inspected. The surface treatment is what separates an Hoffmann Atelier piece from production replicas.
Each unit is unique, numbered, and certified. Hoffmann Atelier produces, finishes, and presents only one hundred units across both editions — closed permanently when complete.
Every Aero Mecanique R9 ships with a numbered Certificate of Authenticity, signed by Alain Hoffmann. The Collector's Edition adds a personalized welcome letter and technical blueprint.
