Multirotor


Multirotor

A multirotor or multicopter is a rotorcraft with more than four rotors. Unlike most helicopters, multirotors, like quadrotors, use fixed-pitch blades, whose rotor pitch does not vary as the blades rotate; control of vehicle motion is achieved by varying the relative speed of each rotor to change the thrust and torque produced by each. Multirotors share similar advantages of quadrotors, versus comparably-scaled helicopters.

Due to their ease of both construction and control, multirotor aircraft are frequently used as amateur model aircraft projects.[1][2][3][4]

e-volo

The e-volo is a prototype electric multicopter with 16 rotors, the first electric multicopter in the world to achieve manned flight.[5] The large number of rotors make it economical, quiet and provide redundancy.
