SoCare-MSI supplies Civilian FPV machine parts

The term "civilian FPV machine" broadly refers to a drone built or customized for First-Person View flying, where the pilot sees a live video feed from a camera on the drone as if they were in the cockpit.

These machines are typically built from individual parts, not bought as a ready-to-fly system. Here is a comprehensive breakdown of the essential and common parts that make up a civilian FPV machine, categorized by system.

The Core Components (The "Must-Haves")

These are the absolute essentials to get the machine in the air.

1. Frame

· Function: The chassis or skeleton that holds all the components together. It determines the drone's size, weight, strength, and orientation of components (e.g., "X" shape for acro, "Long Range" for efficiency).

· Key Specs: Size (e.g., 3", 5"), Arm Style (True-X, Wide-X, Stretch-X), Material (Carbon Fiber).

   2. Flight Controller (FC)

· Function: The "brain" of the drone. It houses sensors (gyroscope, accelerometer) and runs flight control software (like Betaflight) to stabilize the drone and execute your commands.

· Key Specs: Processor (F4, F7, H7), Firmware (Betaflight, Emuflight), UART Ports.

3. Electronic Speed Controllers (ESCs)

· Function: The "muscle controllers." They take signals from the Flight Controller and rapidly switch power to the motors to control their speed and direction.

· Common Form: Often a 4-in-1 ESC board that handles all four motors, simplifying wiring.

4. Motors

· Function: The "engines." Brushless motors spin the propellers to generate thrust.

· Key Specs: Size (e.g., 2207), KV Rating (RPMs per volt, e.g., 1750KV). Lower KV for larger props on 6S batteries, higher KV for smaller props on lower voltage.

5. Propellers (Props)

· Function: The "wings." They bite into the air to create lift and thrust. Their design drastically affects performance, noise, and efficiency.

· Key Specs: Size (e.g., 5.1"), Pitch (e.g., 3.1"), Blade Count (e.g., 3-blade).

6. Video Transmitter (VTX) & Camera

· Function: The drone's "eyes" and "broadcast station." The camera captures the view, and the VTX transmits that video wirelessly to your goggles.

· Key Specs (Camera): Sensor Size (e.g., 1/1.8"), Lens (e.g., 1.8mm), FOV (Field of View).

· Key Specs (VTX): Output Power (e.g., 25mW to 1200+mW), Band/Channel Support (Raceband, etc.), Antenna Connector (MMCX, SMA).

7. Radio Receiver (RX)

· Function: The drone's "ears." It receives control signals from your radio transmitter (controller) and relays them to the Flight Controller.

· Key Protocols: ELRS (ExpressLRS - most popular), TBS Crossfire, Tracer, Frsky.

8. Battery & Cabling

· Function: The "heart and veins." Provides power to the entire system.

· Key Component: LiPo (Lithium Polymer) Battery.

· Key Specs: Cell Count (e.g., 4S, 6S), Capacity (e.g., 1300mAh), Discharge Rate (C-Rating).

The Pilot's Gear (Controlling and Seeing)

These are the parts the pilot holds and wears.

1. Radio Transmitter (TX) / Controller

· Function: The handheld controller you use to pilot the drone. It sends your stick and switch commands to the receiver on the drone.

· Key Features: Gimbals (hall effect are best), Internal/External Module Bay (for protocols like ELRS), Ergonomics.

2. FPV Goggles

· Function: The screen you wear on your head that displays the live video feed from the drone's VTX, creating the immersive FPV experience.

· Key Types: Box Goggles (single screen, good for beginners), Low-Profile Goggles (twin screens, more immersive).

Common Optional/Upgrade Parts

1. FPV Antennas

· Function: Critical for both the VTX (transmitting) and Goggles/Receiver (receiving). They dramatically affect video range and signal quality.

· Types: Omnidirectional (e.g., "Stubby" or "Rubber Ducky") for all-around coverage, and Directional/Patch (e.g., "Mushroom") for long-range in a specific direction.

2. GPS Module

  · Function: Adds GPS coordinates. Used for:

  · Return-to-Home (RTH) safety feature.

  · Displaying coordinates/altitude/speed on your OSD (On-Screen Display).

  · Rescue mode in Betaflight.

3. Action Camera

· Function: To record high-quality, stabilized footage. The FPV camera's feed is usually low-latency but low-quality.

· Common Models: GoPro, DJI Action, Insta360.

4. Low-Noise (LC) Filters

· Function: A small electronic component that cleans up electrical noise from the power system, leading to a cleaner video feed. Many modern ESCs and VTXs have them built-in.

How It All Fits Together: The Signal & Power Flow

1. Pilot Input: You move a stick on your Radio Transmitter.

2. Signal to Drone: The signal is received by the Radio Receiver (RX) on the drone.

3. Brain Processes: The RX sends the command to the Flight Controller (FC).

4. Command to Muscle: The FC calculates needed adjustments and tells the ESCs how fast to spin the motors.

5. Power to Motors: The ESCs draw power from the Battery and drive the Motors, which spin the Propellers.

6. Seeing the World: The FPV Camera sends its video to the Video Transmitter (VTX).

7. Broadcast to Pilot: The VTX sends the video signal via an Antenna to the FPV Goggles on your head.

This ecosystem of parts allows for immense customization, from tiny "toothpick" drones for backyard flying to heavy-lift "long-range" machines for exploring mountains.

The models of DJI Crossover mainly include ‌DJI FPV‌, ‌Avata 2‌, ‌Neo 2‌ and ‌Mini 4 Pro‌. Among them, DJI FPV and Avata 2 are core professional models, and Neo 2 and Mini 4 Pro are entry-level derivative models
