Motors & KV Ratings
Brushless motors are rated by their KV value — the number of RPM per volt with no load.
KV and Battery Voltage
| Build Type | Battery | Recommended KV |
|---|---|---|
| 5" Freestyle | 4S (14.8V) | 2300–2600 KV |
| 5" Freestyle | 6S (22.2V) | 1700–1900 KV |
| 5" Racing | 4S | 2600–2800 KV |
| 7" Long-range | 6S | 1300–1500 KV |
Stator Size
The stator size (e.g., 2207) tells you the diameter (22mm) and height (7mm). Taller stators produce more torque; wider stators spin faster.
Motor Mounting
Most 5" motors use an M3 16×16mm bolt pattern. Always check compatibility with your frame before ordering.
