Introduction: Recently, some netizens asked how to determine the multi-rotor wheelbase. I would like to take this opportunity to briefly introduce the calculation method of the four-axis six-axis eight-axis wheelbase. Everyone has better methods and suggestions to communicate in the message area.
Points to note on wheelbase design:
1. Ensure that the blade does not interfere when it rotates.
2. Each motor is placed on a circle.
3. If the spacing between adjacent propellers is too small, it will have an adverse effect on aerodynamic efficiency.
figure 1
Figure 2 shows the minimum wheelbase obtained when the propeller size is fixed and the distance between the two propellers is 0.
Sin45°=r*2.54/L
D = 3.59 * r
(Note: r is in inches. If you don't understand the definition of the propeller size, you can get back to the "7" in the background of the drone public number to learn about the propeller.)

Figure 2 shows the minimum wheelbase obtained when the propeller size is fixed and the distance between the two propellers is 0.
Sin30°=r*2.54/L
Get L=5.08*r
(Note: r is in inches. If you don't understand the definition of the propeller size, you can get back to the "7" in the background of the drone public number to learn about the propeller.)
