Good product. Thanks. ### ⭐ Poorly round, 30% empty can. *by on Reviewed in the United States 20 December 2025* This motor has the loosest windings you can imagine. There's at least 20 mm of can length that has no rotor engagement and no stator length. There's so much extra winding that's doing nothing but generating heat. It's closer to a 4060 then a 4074, but it's going to use power like a 4074. --- ## 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.tn/products/518849875-surpass-hobby-4074-1700kv-brushless-motor-shaft-5mm-with-water](https://www.desertcart.tn/products/518849875-surpass-hobby-4074-1700kv-brushless-motor-shaft-5mm-with-water) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-27*
