N01 Hit-and-Miss Engine Production Update: Assembly & Testing Complete
Hey everyone, it's the Stirlingkit team! Here's the latest look at where the RETROL & OKMO N01 1/5 scale hit-and-miss vertical gas stationary engine stands on the production line — and confirmation of when it ships.
🔧 Assembly & Testing Now Underway
Every N01 unit goes through a meticulous build process on our production line — fitting the CNC-machined steel core and sand-cast brass hardware, installing the mechanical trip-ignition system, and mounting each engine to its hardwood display base. Our engineering team is now running every unit through hands-on assembly and functional checks, so each engine leaves the factory ready to fire on the first pull.
✅ Quality Control at Every Step
From precision-machined components to the final fit-and-finish check, our QC team holds every N01 to the same standard: tight tolerances, smooth bearing fit, and a clean, quiet running cycle right out of the box. We don't ship anything we haven't tested ourselves.
🚚 Confirmed Shipping Timeline: September 15
With assembly and testing progressing smoothly, we're on track to begin our first shipping batch on September 21, 2026 — matching the ship date shown for current pre-orders. We'll keep posting updates as we get closer, so check back for the next production check-in.
Thank you again for your support and patience — we're working hard to get the N01 onto your workbench as soon as possible! If you have any questions, feel free to reach out to our customer support team anytime.
