Beautiful motor I'd buy again. ### ⭐⭐⭐⭐⭐ Exceptional power *by C***N on May 31, 2026* I have 2 of these motors and the power is simply amazing on 4 cells. ### ⭐⭐⭐⭐⭐ Nice Motor - 8700 RPM on 3S, at 40 Amps with a 12X8 Zinger Prop on the Test Bench. *by B***B on October 30, 2022* Bench Tested: 3S LiPo, 5200mAH/50C Battery, 80A Speed Control, 12x8 Zinger Wood Prop. Ran almost 9000 RPM at 40Amps. Neither motor or speed control got very warm after a couple of minutes of testing. I was planning to run this on 4S in a Kadet 25, but thinking 3S might be enough. Taking a wild guess; thinking this might be a .32 class motor. Update: Aug 8, 2023. Finally flew it. Flew fine on 3S with 11x7 prop, but on 4S with 12 x 8 - Wow! --- ## 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.jp/products/369329813-diamonddynamics-hobbyhh-brushless-motor-4250-800kv-power-1250w-with-4](https://www.desertcart.jp/products/369329813-diamonddynamics-hobbyhh-brushless-motor-4250-800kv-power-1250w-with-4) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-24*
