VELOX-16 is the TECH READS® 1/10 scale RC chassis (the “16” is the model name — 16T drive — not 1/16 scale): JIS spur drive (16T : 32T), Warren-truss rails, bearing-tube knuckles, and a 258 mm wheelbase. It is not the STEM Gear Lab kit and not ZAIN MARU.

Locked specifications (source of truth)
| Item | Value | Notes |
|---|---|---|
| Module | 2.0 mm | Spur only (β = 0°) — no helical thrust |
| Drive / driven | 16T / 32T | Center distance 48.00 mm exact |
| Pressure angle | 20° | JIS involute family |
| Face width | 8 mm | Portrait print, Z = spin axis |
| Bore / shaft | Ø5.0 / Ø4.8 mm | Locked shaft stack |
| Scale | 1/10 | Model name VELOX-16 ≠ 1/16 scale |
| Wheelbase | 258 mm | 1/10 touring class (locked) |
| Track F / R | 178 / 182 mm | Ackermann 19.03° |
| Ride height | 18 mm | Lower A-arm / tie-rod Z = 8 mm |
Ackermann 19.03° is the steering-arm angle that lets the inner wheel turn sharper than the outer wheel in a corner, so the tires scrub less.
The public simulator matches these locks. Printable STL/STEP stay engineering-controlled until first-article approval.
