Not at all. It is about efficiency, agility, and maneuverability of your drone. Just like wheels on a car, the size of the propeller needs to be matched to the rest of the power system. For example, putting 3” props on a motor designed for 5” propellers will result in extremely high RPM and power draw and will create very little thrust. Likewise, putting ...

For a simple answer: no, most mobile robots do not use variable transmissions. I believe it is far easier to just design a motor and gearbox combination that works well in your narrow range of desired speeds, than deal the extra mechanical complexity and cost of a variable transmission. The long answer is that it depends on what you consider a mobile ...

Increasing the number of blades in the props increases the amount of thrust generated but at the cost of efficiency i.e. more current will be drawn as we increase the number of blades. This is due to addition of weight and also because of increased drag, as each blade will have to cut through the turbulent air from more preceding blades which will result ...

Motor and blades must be selected on the basis of amount of thrust required. Estimation of thrust of a motor depends on battery voltage, prop size and motor choice. Changing one of these will change the amount of thrust generated. Motors must be purchased from the manufacturers providing thrust tables that shows how many grams of thrust will be generated ...
