It's only about 2"X 1.5". **Q: can I buy spare glass tubes** A: Need spare tubes with washers I bought this product and had no spare parts glass and tubes. If you want me to be a customer need the parts soon. **Q: For how long can the engine run after it starts?** A: as long as it has fuel.with 90% isopropylic alcohol, it can run for about 7 min.with a small candle, about an hour, but carbon deposits will form on the glass. **Q: How much of the assembly does one do oneself?** A: It comes fully assembled, but will almost certainly need to be lubricated before use. Putting a little 3-in-one oil on the moving parts and the piston made all the difference in the world! Not sure if this is the best oil or not, but it has worked well for us. ## Frequently Bought Together - Sunnytech Mini Hot Air Stirling Engine Motor Model Educational Toy Kits Electricity HA001 - Sunnytech Low Temperature Stirling Engine Motor Steam Heat Education Model Toy Kit For mechanical skills (LT001) - Sunnytech Mini Hot Live Steam Engine Model Education Toy DIY (BJ001) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/2608414-mini-hot-air-stirling-engine-motor-model-educational-toy-kits](https://www.desertcart.be/products/2608414-mini-hot-air-stirling-engine-motor-model-educational-toy-kits) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-21*
