A helicopter includes a propulsion system, gimbal assembly, and a controller. The propulsion system includes a first rotor assembly and a second rotor assembly. The first rotor assembly comprises a first motor coupled to a first rotor and the second rotor assembly comprises a second motor coupled to a second rotor. The second rotor is coaxial to the first rotor and is configured to be counter-rotating to the first rotor. The gimbal assembly couples a fuselage of the helicopter to the propulsion system. The controller is communicably coupled to the gimbal assembly and is configured to provide instructions to the gimbal assembly in order to weight-shift the fuselage of the helicopter, thereby controlling movements of the helicopter.

Systems, devices, and methods for a vertical take-off and landing (VTOL) aerial vehicle having a first GPS antenna and a second GPS antenna, where the second GPS antenna is disposed distal from the first GPS antenna; and an aerial vehicle flight controller, where the flight controller is configured to: utilize a GPS antenna signal via the GPS antenna switch from the first GPS antenna or the second GPS antenna; receive a pitch level of the aerial vehicle from the one or more aerial vehicle sensors in vertical flight or horizontal flight; determine if the received pitch level is at a set rotation from vertical or horizontal; and utilize the GPS signal not being utilized via the GPS antenna switch if the determined pitch level is at or above the set rotation.

An aerial drone having a flying platform and has detachable and interchangeable cabins. Each cabin can have an energy storage unit that supplies energy to the flying platform so the when cabins are exchanged, a fresh supply of energy is made available to the flying platform. The flying platform and the cabins can have motorized wheels as well as floatation devices for water landing.

An aircraft support leg (2), the support leg (2) being movably connected to a main body of an aircraft. The support leg (2) can rotate to at least a first position and a second position. At the first position, an angle is provided between the support leg and the main body of the aircraft, and at the second position, the support leg (2) substantially abuts against the main body of the aircraft or is at least partly arranged in the main body of the aircraft. Such a support leg is convenient for the storage of the aircraft. Also disclosed are a control method for said support leg and an aircraft having said support leg and a control method for the aircraft.

The present disclosure provides a device for detecting carbon emission of a passive house. The device for detecting carbon emission of a passive house is arranged on a metal rain cap at a top of a chimney. The device for detecting carbon emission of a passive house includes an unmanned aerial vehicle, a guide assembly, and two landing gear assemblies. The two landing gear assemblies are arranged at a bottom of the unmanned aerial vehicle, the guide assembly is arranged at a bottom of the two landing gear assemblies, and the guide assembly includes two split assemblies. The two split assemblies correspond one-to-one to the two landing gear assemblies, and the split assemblies are in linked connection to the landing gear assemblies. In the device for detecting carbon emission of a passive house, the unmanned aerial vehicle, the guide assembly and the two landing gear assemblies are arranged to cooperate with each other. The present disclosure can have a function of delivering and fixing a device for detecting carbon emission to a chimney by means of an unmanned aerial vehicle, and can further effectively avoid the shielding of the metal rain cap on the chimney and make the detector smoothly correspond to an air outlet of the chimney. The present disclosure is greatly convenient for personnel to use.

An unmanned helicopter platform includes a fuselage, a tail coupled with the fuselage, a payload rail coupled with and extending along the fuselage and a main rotor assembly coupled with the fuselage. The tail includes a tail rotor and a tail rotor motor. The tail is removably coupled to the fuselage. The main rotor assembly includes a main rotor having an axis of rotation and a main rotor motor.

A battery powered octocopter drone with a protective frame. An articulating arm is mounted to the drone with a battery powered chain saw positioned along the end of the articulating arm. The chainsaw allows for the trimming of remote trees and bushes previously only accessible by a ladder or bucket lift. The drone is adjustable forward/aft to compensate for the center of gravity. The drone includes a remote control receiver, telemetry and an antenna allowing an operator to control all aspects of the drone from a remote position.

A heavy-lift UAV frame includes a central frame portion and a pocket area for receiving an avionics package. Top and bottom plates are secured to the central frame portion and include four corner members that extend diagonally outward therefrom. A plurality of boom hinges are interposed between each of the corner members pivot a boom arm between an extended position for flight and a retracted position for storage and transport. Each boom arm and hinge combination includes a complementary dimension to one side of the central frame portion to position a boom arm parallel thereto when in the retracted position. A plurality of landing gear hinges are positioned along the bottom of the frame and transition a plurality of landing gear legs between a ready for flight position and a storage position. In the storage position each of the legs are positioned diagonally beneath the central frame portion.
