Some of the best and most known drones

1. SOME OF THE BEST DRONES

2. INDEX
Multi Rotor Drones.
Fixed Wing Drones.
Single Rotor Helicopter.
Fixed Wing Hybrid VTOL.

3. MULTI ROTOR DRONE
Multirotors are UAVs that use more than two rotors with fixed-
pitch spinning blades that generate lift. By changing the speed of
the rotors so that the thrust generated is greater than, equal to or
less than the forces of gravity and drag acting on the aircraft, the
drone can be made to ascend, hover or descend.

4. FIXED WING DRONE
A fixed-wing drone has a rigid structure which generates lift under
the wing due to forward airspeed. This is produced by either an
internal engine or electric motor-controlled propeller. They will
require either a handheld or runway take-off and can fly
continuously over long distances as opposed to hovering.

5. SINGLE ROTOR HELICOPTER
While a multi-rotor has many different rotors to hold it up, a single
rotor has just one, plus a tail rotor to control its heading.
Helicopters are very popular in manned aviation, but currently
only fill a small niche in the drone world

6. FIXED WING HYBRID VTOL.
Hybrid VTOL Fixed-Wing UAVs combine the benefits of multi-rotor
platforms with fixed-wing drones and transition between the two
modes during flight. ... The ability to vertically take-off and land,
without the need for a launcher or runway, means these drones
can be operated in almost any location
