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 ...
