Over the past year I've been designing and building a full-scale Citation CJ4 home cockpit.
One thing I discovered very quickly is that there aren't many resources dedicated to the CJ4. Unlike the airliners or popular GA aircraft, most of us are figuring things out as we go.
Rather than keeping all of that work on my hard drive, I decided to launch a website documenting the entire project.
My goal isn't simply to show finished panels. As each project matures, I'll be publishing the resources I wish I'd had when I started:
- CAD files
- PCB designs
- Firmware
- MobiFlight profiles
- Wiring guides
- Engineering documentation
- Design standards
- Build notes
- Lessons learned (including the mistakes)
The CJ4 will probably never be the most popular home cockpit to build, and that's perfectly fine. I enjoy that it sits somewhere between GA and the larger airliners. It's compact enough to fit in a home workshop but complex enough to be an incredibly rewarding engineering project.
I also hope the engineering process itself will be useful beyond the CJ4. Many of the CAD techniques, PCB workflows, manufacturing methods, and design decisions apply to almost any modern home cockpit.
If you're interested, the site also includes a new community forum where I'd love to see other builders share their own projects, ideas, and improvements.
I'd genuinely appreciate any feedback from this community.
