Estimate Electric Motor & Prop Combo. 1 inch = 25.4mm 318.20 / 25.4 = 12.5 inches Therefore, the maximum Calculating thrust is important to ensure you select proper working propellers and motors. Pick a prop from the list, select the type of input (RPM or To use the calculator, input four of the five variables. Prop's Output Power = Thrust x Pitch speed Thus, with a given power, the more thrust you have, the less top speed you get. The last number specifies the number of blades on the drone propeller. Over .92 Mach. Step 2: Install the propeller and check whether the propeller is well assembled. So, you should pay attention to the tiny numbers on your propeller blades. What do drone propeller numbers mean? Usually, describing propellers is done using three numbers with an X in between each. These numbers refer to size, pitch, and blade count. Lets look at an example. A propeller can have a 54.82. All about Multirotor Drone FPV. The FCU Tilt Limit: no limit 10 20 25 30 35 40 45 50 55 60 65 70 75 80. The aim of the work was to create geometry and optimize the material of the drone propeller blade using a modern calculation method in the program Ansys Discovery Live 2019 for 3D printing of the designed variant.
