9‑Cylinder Brushless Motor – 70,000 RPM Handmade Beast! 🚀
I built a 9‑cylinder inner‑rotor brushless motor from scratch – 3D‑printed frame, nine hand‑wound bobbins, neodymium magnets, and plenty of copper wire. The result? A screaming 70,000 RPM. Would you trust this on a model plane? Watch the full build and decide.
