What is multi rotor system?
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.
How are multi rotor planes controlled?
¶ A multicopter is a mechanically simple aerial vehicle whose motion is controlled by speeding or slowing multiple downward thrusting motor/propeller units.
What are 3 uses for Multicopters?

What are multi rotor drones?
A multirotor or multicopter is a rotorcraft with more than two lift-generating rotors. An advantage of multirotor aircraft is the simpler rotor mechanics required for flight control.
What is the advantage of multi-rotor drone?
Pros. Greater manoeuvrability – One of the biggest advantages of multirotor aircraft is their manoeuvrability compared to fixed-wing aircraft. This enables them to fly in areas other drones can’t reach, hover in a stationary position and provide vertical take-off and landing (VTOL) ability.
How much can a multi-rotor carry?
This model, called “Dauntless”, is designed to set new records for what multi-rotor UAVs can carry. At 78 pounds, the Dauntless has easily lifted an additional payload of 100 pounds as a tethered quadcopter. It is designed to lift over 200 pounds as an octocopter, with a generator-powered flight time of several hours.
How do Tricopters work?
A tricopter has two rotors that are spinning in opposite directions but there is a rotor left who produces torque that tries to spin the tricopter. Because of this, a rear servo was used to tilt the rear rotor to compensate this torque in the same manner a helicopter tail rotor does.
How far can a multi-rotor drone fly?
A new super class of long range multi-rotor drones are now competing with fixed wing drones but with all the advantages of multirotor drones. The best products in this genre supports a maximum range of over 30 kilometres and flight times of over 60 minutes.
