caption_attribution_description: English: World’s first manned flight with an electric multicopter. At the end of October 2011, Thomas Senkel of e-volo had completed a series of unmanned tests and was ready for the first manned flight on an airstrip in Karlsruhe, Germany. The flight lasted one minute and 30 seconds. Deutsch: Weltweit erster erfolgreicher bemannter Flug mit einem elektrischen Multikopter. Nach einer Entwicklungszeit von ca. 1 Jahr und einer Reihe von unbemannten Tests gelang Thomas Senkel vom Team e-volo der weltweit erste bemannte Flug mit einem Prototyp des neuartigen e-volo Multikopters. Français&#160;: Le premier vol habité avec un multicopter électrique. A la fin octobre 2011, Thomas Senkel de e-volo a réalisé une série de tests inhabités pour se préparer pour le premier vol habité sur une piste de Karlsruhe, en Allemagne. Le vol a duré une minutes et trente secondes. Türkçe: İnsan taşıyabilen elektirikli multikopter. Alman havacılık şirketi ‘e-volo’, dünyanın ilk elektrikle çalışan ve insan taşıyabilen çok pervaneli hava aracını geliştirdi. Uçlarında motor ile pervane olan ve merkezde birleştirilmiş çubuklardan oluşan ‘multikopter’ cinsi çevreci hava aracı, geçtiğimiz günlerde Almanya’nın güneybatısındaki bir iniş pistinde ilk kez denendi. e-volo’dan Thomas Senkel’in pilotluğunu yaptığı multikopter, yaklaşık 1 dakika 30 saniye havada kaldı.
context_page_description: 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. Unlike single- and double-rotor helicopters which use complex variable pitch rotors whose pitch varies as the blade rotates for flight stability and control, multirotors often use fixed-pitch blades; control of vehicle motion is achieved by varying the relative speed of each rotor to change the thrust and torque produced by each.
  Due to their ease of both construction and control, multirotor aircraft are frequently used in radio control aircraft and unmanned aerial vehicle projects in which the names tricopter, quadcopter, hexacopter and octocopter are frequently used to refer to 3-, 4-, 6- and 8-rotor rotorcraft, respectively. There is also the X8 configuration that is similar to the quadracopter design, except that it has eight rotors; the lower of which have a reversed rotation direction.
  In order to allow more power and stability at reduced weight, coaxial rotors can be employed, in which each arm has two motors, running in opposite directions which cancels out rotational torque.

  Due to their ease of both construction and control, multirotor aircraft are frequently used in radio control aircraft and unmanned aerial vehicle (UAV) projects in which the names tricopter, quadcopter, hexacopter and octocopter are frequently used to refer to 3-, 4-, 6- and 8-rotor rotorcraft, respectively. There is also the X8 (also called octo-quad) configuration that is similar to the quadracopter design, except that it has eight rotors; the lower of which have a reversed rotation direction.
  In order to allow more power and stability at reduced weight, coaxial rotors can be employed, in which each arm has two motors, running in opposite directions which cancels out rotational torque (one facing up and one facing down).
  Also possible is the addition of horizontal propellers These types of rotorcraft (which have just 4 vertical propellers) are called quadplanes.
