Drive characteristic:

Kv [rpm/V]: No load current [A]: Rmot [W] :
Gearbox Ratio : Efficiency:

Calculated values:

Drive speed : rpm Propeller speed : rpm Vpitch : m/s  
Drive efficiency : Drive chain efficiency : Terminal voltage (drive): Volt
Power dissipation: drive : Watt Static thrust : kg Flight speed @ max prop efficiency : m/s
Shaft power [W] Drive current : Ampere

Disclaimer: The calculated values are an approximation.  The calculations are based on certain assumptions of accu, motor and prop data.
