It is also possible to fit quadcopters with guards that enclose the rotors, further reducing the potential for damage. However, as size increases, fixed propeller quadcopters develop disadvantages relative to conventional helicopters. Increasing blade size increases their momentum.
Quadcopters can also be fitted with protective casings that surround the rotors, reducing the risk of damage. However, as the quadcopter's dimensions increase, fixed-wing designs begin to have disadvantages compared to traditional helicopters. As propeller blades grow in size, they gain more momentum.
