Methodology & Disclaimer

This calculator uses standardized aerodynamic estimation models. The Amp Draw is calculated using the formula: Amps ≈ (D⁴ × P × RPM³ × k) × Blades. Static thrust is estimated using momentum theory based on prop diameter, pitch, and rotational velocity. Disclaimer: Calculations are theoretical estimates. Real-world performance depends on motor efficiency, ESC timing, temperature, altitude, and battery health. Always verify your current draw with a watt meter during static testing before flight.
