3xD 1.2-rc1 release notes
10 November 2026 · Release candidate · Superseded by 1.2-rc2
3xD 1.2-rc1 introduces the owner-selected chassis cutout pattern: the 3xD logo in the battery area, swept blade openings at the front shoulders and paired chevrons in the two small rear-window areas. It builds on 1.1-rc1.
What changed
- The two battery-area windows are replaced by a traced 3xD logo through-cut, with two 2 mm bridges retaining the centre of the D.
- Four swept front blade slots replace the two shoulder windows.
- Paired chevron slots replace the two small rear chassis windows. The large motor-clearance opening is unchanged.
Compatibility and replacement parts
Separate 3 mm GRP and 4 mm printed chassis replacement packs retain their respective thicknesses, outline, mounting positions and underside countersinks. Replace only the chassis plate; use with the matching complete 1.0-rc2 base and 1.1-rc1 wider side rails. This is a changed-part update, not a complete car kit. The motor pod plate and restored two-slot rear brace are unchanged.
Validation and status
Both chassis meshes were checked for a single connected watertight solid, correct thickness, matching top profiles and preservation outside the intended cutout regions. The motor region is preserved. The owner selected the styling; physical fit, plate stiffness, fatigue, electronics and battery support, and full suspension clearance still require checks. No speed or handling improvement has been measured. This candidate is superseded by 1.2-rc2, which centres the logo under the battery and widens the D bridges.
