Welcome to Jon's Hangar
A personal RC aviation hangar built around aircraft that matter, practical experimentation, careful documentation, and the rabbit holes that turn good questions into better decisions.
Visitor Briefing
The site is not a chronological blog. Aircraft Bays tell the main story; the Workshop, Electronics Bench, 3D Print Lab, Plans Room and Flight Line reveal the work behind it. Rabbit Holes explain why a decision changed.
Restoration, construction, training, systems and flight history stay centered on the aircraft.
Enter the bays → Active WorkCurrent work without turning the site into a dated news feed.
Open the workboard → OrientationSee how the aircraft bays, specialist rooms and deeper project stories connect.

Each bay has its own identity and history. Technical work may cross the whole hangar, but aircraft-specific truth always comes back to the aircraft.
Preserve what is sound. Rebuild only with cause. Follow the structure, greenhouse, cockpit, systems, finish and historical record of a major restoration still working toward release.
Enter the L-4 Bay →
Not a hunt for speed: a giant Cub shaped around floaty handling, authority, long useful flights, serviceability and progressively better questions.
Enter the J-3 Bay →
The 1.3 m trainer that connects SAFE, simulator work, telemetry and the return to flying with the giant-scale projects that followed.

Rooms and Zones
The specialist rooms are where construction methods, electronics, fabrication, records and field preparation can be explored without burying the aircraft story.
Construction, restoration, tools, jigs, structures and methods.
Room 02Radio systems, redundant power, telemetry, lighting and testing.
Room 03Prototype, fit, revise, print, install — with evidence states kept honest.
Room 04Project Bibles, manuals, drawings, evidence and selected downloads.
Zone 05Release gates, ground tests, maiden work, telemetry review and as-flown records.
Room 06Aircraft milestones, design concepts, people, clubs, fields and flying.
Currently on the Bench
Follow the active restoration, build and documentation work across the hangar.
Structural restoration, fabrication, systems integration and release preparation. Testing and flight remain a future release phase.
Serviceable structure, independent control architecture, propulsion development, lighting and pre-covering hold points.
Aircraft, manuals, fabrication, photographs and project decisions are being connected into one easy-to-follow story.
Recently Added
A quick path for returning visitors. Each notice leads to the permanent aircraft chapter or working room where the complete story belongs.
Propeller clearance, modeled operating points and a manufacturer-guided plywood motor-box concept bring the L-4 power study to the firewall.
Follow the L-4 story → Published InvestigationFull-size mockups showed how pack width and removal path narrowed the 12S battery choices. The final packs and CG remain open.
Follow the fit study → Modeled ComparisonSee the separate BadAss and Scorpion comparison, with battery weight included in the modeled flying weight.
Review the comparison →The Library
Manuals, plans, photographs, test results, wiring maps and lessons learned provide the technical foundation for each project.
