Drone Thrust & Motor Sizing Calculator
EveryDroneCalculate required thrust per motor and estimate hover current
Thrust & Motor Sizing Calculator
Assumptions
- Thrust divided equally among motors
- T/W ratio of 2.0 is typical for stable flight
- ESC rating should exceed peak current with margin
When This Estimate Breaks Down
- Actual thrust depends on propeller-motor matching
- Voltage sag under load affects motor performance
- KV/RPM optimization requires thrust stand testing
Required Thrust & Current Estimates
Required Thrust per Motor
1000gf
(9.81 N)Required thrust for the entered weight and target thrust-to-weight ratio.
ESC Avg Current3.5A
ESC Peak Current4.2A
ESC Recommendation5A ESCConfirm against measured current and ESC operating ratings
Hover Power198W
Thrust is the target requirement. Current and ESC values are hover-based estimates, not measurements at that target thrust.
