Im totally new to brushless and I dont mind spending a little more to be completely satisfied.

Motor rpms is based solely on battery voltage and motor kv. Each motor has a maximum recommended rpm which must be exceeded using the motor and/or battery voltage you selected. Feigaos and the like are good for around 40k rpm max (30-35k preferable), while Neus are higher-end and can get upwards of 55krpm. The calculator still displays the speed, but simply warns you that something may be wrong. Which calculator were you using and what parameters were you entering?
Threaded Mode
