About this calculator

Overview

Drone motor selection depends on KV rating, propeller size, battery voltage, and desired thrust. Higher KV = higher RPM but lower torque. Proper motor-prop-battery matching ensures efficient, stable flight.

💡

Pro Tips

Low KV (200-600): large props, high efficiency, heavy lift.
High KV (2000+): small props, high speed, racing drones.
50% throttle should hover for efficient setup.
ESC current rating must exceed motor max draw.

Fun Facts

"KV = RPM per volt (no-load); 1000 KV × 11.1V = 11,100 RPM."
"4S LiPo = 14.8V; 6S = 22.2V nominal."
"Thrust-to-weight ratio >2:1 for stable flight."
"Brushless motors are 85-90% efficient vs 50% brushed."

Formula: RPM = KV × Voltage; Thrust ≈ 2-3× total drone weight
