What ratio should I use?
For general flying/filming, 2:1 is good. For racing, 4:1 or higher is common. Below 1.5:1, the drone will feel sluggish and hard to control.

How to Use
Step-by-step instructions
- 1Enter the total weight of the drone (including battery).
- 2Enter the number of motors.
- 3Enter the desired thrust-to-weight ratio (usually 2.0).
- 4The calculator will show the required thrust per motor.
Thrust Requirements
Calculates the required thrust per motor based on the total drone weight and the desired thrust-to-weight ratio.
Thrust/Motor = (Weight × Ratio) / MotorsVariables:
Ratio2:1 is standard for good controlMotorsNumber of motors (e.g., 4 for quad)Example
1kg Quadcopter
Inputs:
Weight:1000g
Motors:4
Ratio:2:1
Steps:
- 1.Total Thrust = 1000 * 2 = 2000g
- 2.Per Motor = 2000 / 4 = 500g
Result:
500g Thrust / Motor
