Drone Endurance Calculator

Pick a preset or dial in battery, motors, props, FC/ESC, payload, altitude and MTOW to estimate hover and cruise flight time for your next build.

Quick start

Cell count (S)e.g. 4S, 6S

Capacity (mAh)

Usable capacityLiPo typically ~80%

Battery weight (g)

Auto-estimate battery weight from cells × mAh

Motors

Prop diameter (inches)

Prop pitch (inches)Affects cruise efficiency

Motors total weight (g)

Props total weight (g)

System efficiencyMotor + ESC + prop (0.5–0.75)

Weights add into all-up mass — the biggest driver of hover power.

Frame (g)

Flight controller (g)

ESC / stack (g)0 if AIO / FC includes ESC

VTX + camera / air unit (g)

Other (RX, GPS, wiring) (g)

Payload (g)GoPro, dropper, mapping gear

Altitude (m ASL)Thinner air needs more power

MTOW limit (g)0 = no limit check
