Some projects are built for the market. Others are built because something in you refuses to let them go.

Diamond belongs to the second category.

We believe good engineering is not about making everything complicated or expensive. It is about choosing the right solution for the job, testing it honestly, learning from what fails, and improving what works.

Not cheap. Smart.

Piece by piece. Decision by decision.

Follow the project. See the process. Ask questions.

RSG Diamond is being developed in the open. We share the real engineering process — design decisions, prototypes, testing, mistakes, corrections and progress.

Not as a polished story written after the aircraft is finished, but as it happens.

Diamond is being built in public. You are welcome to follow the journey.

RSG Diamond is developed with its engineering process visible from the outside.

We share design decisions, CAD development, prototypes, materials, testing and the reasoning behind the solutions we choose.

Not just what we build — but why we build it that way.

FULL-SCALE CABIN MOCK-UP

The full-scale mock-up of the Diamond cabin was built to verify key design assumptions before progressing to the structural design.

It allowed us to evaluate:

• overall geometry and proportions,

• seating position and ergonomics,

• visibility,

• instrument panel reach,

• cabin width and internal clearances,

• entry and exit,

• structural reference geometry.

The mock-up provided something CAD alone could not: real-scale human feedback.

Lessons learned at this stage were transferred directly into the subsequent development of the Diamond structure and cabin.
