1. A multicopter system comprising:
a chassis, with at least one lift motor and at least four control motors mounted to the chassis;
at least two lift propellers configured to create a vertical thrust;
at least four control propellers configured to generate a horizontal thrust;
a transmission connecting the at least one lift motor to the at least two lift propellers;
the at least four mounted control motors each connected to a respective control propeller,
wherein the at least two lift propellers and the at least four control propellers are coplanar or in parallel planes; and
wherein the at least two lift propellers are at least twice as long as the at least four control propellers;
a computer mounted on the chassis, the computer in communication with the at least four control motors and the at least one lift motor, the computer configured to control the at least four control motors to vary rotation speeds of the at least four control propellers and to control the at least one lift motor to vary rotation speed of the at least two lift propellers such that the rotation speed of the at least two lift propellers is always varied less frequently than the rotation speeds of the control propellers during maneuver operations;
an electric power source mounted on the chassis, the electric power source connected to the at least four control motors; and
an antenna mounted on the chassis, in communication with the computer.
