Drone Motor Specification Calculator

This calculator helps you determine the required motor specifications based on your drone's weight and desired performance. The calculations are based on these key principles:

• Thrust Requirement: To fly properly, a drone needs to generate more thrust than its weight. The Thrust-to-Weight ratio determines how agile your drone will be.
• Motor KV & Voltage: The KV rating (RPM per volt) combined with your battery voltage determines motor speed, which affects thrust generation.
• Propeller Efficiency: The prop diameter and pitch affect thrust generation and efficiency. Larger props generally produce more thrust but require slower motors.
• Current Draw: Higher thrust requirements lead to higher current draw, which affects battery selection and flight time.

The thrust calculation uses the formula T = C_T × ρ × n² × D⁴, where C_T is the thrust coefficient, ρ is air density, n is rotations per second, and D is propeller diameter.
