Purpose‑built for flight sim: A printable, mechanically sound single control column that brings Boeing‑style yoke ergonomics to your sim pit without exotic parts or CNC.
Originality in this revision: A ground‑up simplification around 75 mm OD PVC, deletion of the linear actuator, and a reshaped control head—now with hall sensors—for precise, drift‑free inputs and long‑term reliability.

Essential for builders: All parts fit a 220 × 220 mm bed (Ender‑3 class), use commonly sourced hardware, and come with a complete build guide—so you can focus on flying, not guesswork.
Key improvements in this release:
 
75 mm OD PVC core (highly requested) for easier sourcing and a lighter, cleaner build.
Linear actuator removed → fewer moving parts, simpler assembly, less maintenance.
Hall‑sensor control head + hall‑sensor pitch lane → smooth, precise, contactless measurement.
Optional gas‑strut head → markedly better, more realistic feel (widely praised by early builders).
Roll‑channel damping → accepts up to two rotary dampers to tame oscillations and improve centring.

Note: Suitable dampers are becoming harder/more expensive to source—see “Limitations & sourcing notes.”

Refined yoke & control‑head geometry for fit, serviceability, and feel.
 
What’s included (downloads):
STL files only for the SCC assembly (yoke, control head, base, and related parts).
STL for the gas‑strut head (alternative to spring‑based feel).
A link to the build guide (parts list, wiring, tuning tips, exploded views & assembly references).
Temporary build/overview videos (until the new YouTube series is published):

Limitations & sourcing notes
Rotary dampers: Historically used models are harder to source and pricier in some regions. The design supports one, two, or none; feel is tunable. The guide notes alternatives and mounting tips.
PVC pipe: Must be true 75 mm OD. Regional nominal sizes can vary—verify OD before printing press‑fit components.

Controller boards: Use a controller that supports hall‑sensor analogue inputs (see guide for wiring).
