Drone Motor Calculator
Find the per-motor thrust needed for a multirotor.
Pick motors that together give enough thrust to fly responsively.
The math behind it
thrust per motor = total weight x thrust-to-weight ratio / number of motors. Aim for a TWR of 2 for good control.
Worked example
1500 g quad at 2:1 needs 750 g thrust per motor.
FAQ
What TWR do I want?
About 2:1 for general flying, 4:1+ for racing.
