T/W and current are in typical range.

Check flight timeCheck current consumption

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
