1. Quadcopter Frame

  • Frame Size: Choose based on your requirements (racing, freestyle, camera drone). Common sizes are 150mm (micro), 250mm (freestyle/racing), 450mm (camera/freestyle).
  • Material: Carbon fiber is lightweight and durable. Avoid plastic unless for toy drones.
  • Mounting: Ensure the frame supports the components you’re planning to use (motor mounting pattern, flight controller size, etc.).

2. Motors

  • Motor Size: Defined by numbers (e.g., 2205). First two digits refer to the stator diameter; the second two are stator height.
  • KV Rating: Determines motor speed. Higher KV = faster motor, but less torque. Choose based on propeller size and battery.
  • Type: Brushless motors are most common due to efficiency and durability.

3. Electronic Speed Controllers (ESC)

  • Amperage Rating: Choose ESCs that support the motor’s current draw (check motor datasheets). Add a 20-30% safety margin.
  • Number of ESCs: 4 individual ESCs or a 4-in-1 ESC board. 4-in-1 simplifies wiring but may be harder to replace individually.
  • Firmware: BLHeli_S or BLHeli_32 are common for advanced features and performance

4. Flight Controller (FC)

  • Processor: F7 or F4 processors are common. F7 provides more future-proofing and features.
  • Gyros: Look for FCs with high-performance gyros for smoother flight. MPU6000 is reliable for most builds.
  • UART Ports: Ensure enough ports for your accessories like GPS, telemetry, and receiver.
  • Firmware: Betaflight or iNav for FPV racing/freestyle, or ArduPilot for more advanced features.

5. Propellers

  • Size: Propeller size should match the motor and frame size. Common sizes are 5-inch for freestyle and racing, 6-8 inch for medium, and larger for camera drones.
  • Pitch: A higher pitch increases speed but reduces flight time. Choose based on your flying style.
  • Material: Nylon with glass fiber is durable and affordable.

6. Battery (LiPo)

  • Cell Count: Defined as 3S, 4S, etc. More cells mean higher voltage (3S = 11.1V, 4S = 14.8V).
  • Capacity (mAh): Larger capacity gives longer flight time but increases weight. Balance capacity with weight for your drone size.
  • C Rating: Defines discharge rate. Higher C rating = more current output. Choose at least 30C-50C for racing drones.

7. Radio Transmitter & Receiver

  • Channels: At least 6-8 channels are recommended for basic drone control.
  • Range: Choose a transmitter with sufficient range (consider 2.4GHz or long-range 915MHz systems for FPV).
  • Receiver Type: FrSky, FlySky, Spektrum, or Crossfire depending on your preferred brand and features.

8. FPV Camera & Video Transmitter (VTX)

  • FPV Camera: Look for low-latency cameras with high-resolution (600TVL to 1200TVL) for a clear FPV feed.
  • Video Transmitter (VTX): Choose based on the required range (25mW for short-range, 200-600mW for longer ranges).
  • VTX Band: Make sure your VTX operates on legal frequencies in your country (typically 5.8GHz).

9. GPS Module (optional)

  • Purpose: Adds features like Return-to-Home (RTH) and position hold. Essential for camera drones and advanced features.
  • Compatibility: Ensure it’s compatible with your flight controller firmware.

10. Power Distribution Board (PDB)

  • Current Rating: Ensure it supports the combined current draw of all your components.
  • Built-in Features: Some PDBs come with built-in voltage regulators or OSD (On-Screen Display) for telemetry.

11. Miscellaneous Parts

  • LEDs: For night flying or visibility.
  • Buzzer: Helps locate the drone in case of a crash.
  • XT60 Connectors: Common connectors for LiPo batteries.
