Science Popularization | FPV Basic Technology Theory for Crossover Aircraft

     A Racing Drone, also known as a racing drone, is a small unmanned aerial vehicle used for first person view (FPV) flight competitions and stunt flying, capable of flying quickly in narrow spaces. Usually used for tasks such as photography, video recording, exploration, search and rescue, and also commonly used for entertainment and competitions

    Compared to traditional drones, time traveling aircraft have a smaller size and lighter weight, and are typically controlled for flight attitude by high-precision gyroscopes and acceleration sensors. Crossover aircraft typically use high-speed electric motors and propellers, which can quickly fly and perform various maneuvers in narrow spaces.

Basic knowledge of time traveling aircraft

A time traveling drone is a type of unmanned aerial vehicle that uses high-speed electric motors and high-speed propellers for flight. Its flight principle is similar to traditional drones, changing the flight attitude and speed by controlling the speed of the electric motor and the angle of the propeller. Crossover aircraft typically use high-precision gyroscopes and accelerometers to sense flight attitude and position, and adjust the speed of the electric motor and the angle of the propeller through control algorithms to maintain a stable flight attitude and speed.

The electronic equipment of the time traveling machine is the core part to achieve its functions. Usually includes a main control board, sensors, motor drivers, wireless communication modules, etc. The main control board is the core of the entire electronic device, responsible for receiving and processing data from sensors, and outputting control signals to motor drivers based on control algorithms. Sensors typically include gyroscopes and acceleration sensors, which are used to sense flight attitude and position. The motor driver is responsible for controlling the speed and direction of the electric motor to achieve adjustment of the flight attitude. The wireless communication module is used to receive signals from the ground controller and send data to the ground controller.

The battery of the time traveling machine is a key component that provides energy. High energy density, lightweight, and durable lithium batteries are commonly used. Energy management involves how to allocate and use battery energy reasonably to ensure that the aircraft can fly continuously and stably. Energy management typically includes aspects such as battery charging management, discharge management, temperature management, etc., to ensure the safety and effectiveness of batteries.

The navigation and positioning technology of a time traveling aircraft is one of the key technologies for achieving autonomous flight. Time traveling machines typically use devices such as GPS, IMU, and barometers for navigation and positioning. GPS is used to provide geographic coordinates and time information, IMU is used to provide flight attitude and angular velocity information, and barometer is used to provide altitude information. By combining these devices, the time traveling machine can achieve precise navigation and positioning, and complete various tasks.

The communication protocol of the drone is one of the key technologies for achieving communication between the ground controller and the unmanned aerial vehicle. Communication protocols typically include control protocols and data protocols. Control protocols are used to transmit control signals, such as flight instructions and parameters; The data protocol is used to transmit data signals, such as sensor data and image data. The design of communication protocols needs to consider aspects such as transmission efficiency, stability, and security to ensure accurate transmission of control signals and data signals.


The difference between a time traveling aircraft and a drone
Design purpose and performance characteristics: Crossover aircraft: mainly used for competition, entertainment, and extreme flight, characterized by fast speed, strong maneuverability, sensitive response, and the ability to make rapid acceleration, steering, and rolling actions in a short period of time. It has extremely high flight flexibility and first person perspective flying experience (FPV). Time traveling machines are usually small in size, have a short battery life, and often use DIY assembly methods for personalized customization and performance optimization. Drones: Covering a wider range from consumer to industrial levels, their application areas include aerial photography, remote sensing surveying, agricultural crop protection, logistics distribution, security patrols, scientific research experiments, etc. Drones usually focus on stability, endurance, and payload, and in many cases require carrying devices such as cameras and sensors for data collection. Therefore, reliability and practicality are more emphasized in design.

Construction complexity: Crossover aircraft: compact structure, focusing on weight reduction and improving power performance, usually using lightweight materials, equipped with high-speed brushless motors, high-performance motors, and small flight control systems. Drones: The construction may be relatively complex, and in addition to basic flight systems, they may also be equipped with more advanced navigation systems, obstacle avoidance systems, visual positioning systems, as well as larger capacity batteries and more stable structures to cope with harsh environments.

Control method: Crossover aircraft: Generally, first angle flight is achieved through FPV glasses, and the operator can see the scene in front of the Crossover aircraft in real time, and operate it with a high-speed responsive handle or joystick, requiring high control skills. Drone: It can be remotely controlled through a remote control or ground station software, and can also set automatic flight paths and perform preset tasks. The difficulty of control can vary according to different models and functional requirements.

Application scenario: Time traveling aircraft: mainly used for drone racing, fancy flying performances, small item delivery experiments, etc., emphasizing speed and agility. Drones are widely used in various fields such as commerce, industry, scientific research, and public services, including aerial photography, geographic mapping, disaster relief, crop monitoring, and cargo transportation. They focus on task execution efficiency and data collection quality. In summary, time travel aircraft tend to focus on extreme sports and competitive entertainment, emphasizing speed and handling pleasure, while drones cover a wider range of practical and commercial uses, emphasizing stability and task execution ability.
