RC Speed Calculator

Calculate actual and scale speed from motor RPM, gear ratio, and wheel size.

How to Use

  1. Choose KV×Voltage mode or enter motor RPM directly.
  2. Enter your motor KV rating and battery voltage (e.g., 3S = 11.1V, 4S = 14.8V, 6S = 22.2V).
  3. Enter the gear ratio (pinion teeth ÷ spur teeth, e.g., 18/45 = 2.5).
  4. Enter wheel diameter in millimeters.
  5. Set the scale denominator (e.g., 10 for 1:10 scale).
  6. Click Calculate to see actual speed and equivalent full-scale speed.
