Got it! With 33.3V (9S), 1000kV motor, and 16:1 gearing:

Motor RPM: XXXXXX  
Wheel RPM: ~2,081 (17" wheel, ~0.63m dia, 1.98m circ)  
No-load speed: ~247 km/h (153 mph)—still high for practical use.  

Actual top ~200 km/h after losses. Too fast? Drop to 700kV for ~173 km/h no-load, or adjust gearing to 20:1 for ~198 km/h. Thoughts? 🚀
