Drone Thrust Calculator

This drone thrust calculator helps you determine the motor thrust required of your drone's motors to get up and flying.

How to Use the Drone Motor Thrust Calculator:

  • Note: Units of measurement can be whatever you would like...just be consistent across each input (i.e., if you use lbs, stick to lbs)
  • Weight: input what you know about the weight of your drone
  • Power-to-Weight Ratio: often expressed in grams or ounces, this is the weight that one motor can lift! It is safe for most people to assume a 2:1 ratio, which would allow you to hover your drone at half throttle. If you want a racing drone or plan to shoot FPV style videos, you will want to bump up your ratio to between 4:1 and 7:1 (note that the higher your ratio, the more difficult it will be to fly your drone smoothly--a ratio of 7:1 would be for extreme flying by highly experienced pilots only). The type of conditions you plan to fly in will also make a difference; for example, flying in windy conditions will be harder if your power-to-weight ratio is 2:1 rather than 4:1.
