FPV camera -> VTX -> antenna -> goggles or receiver

Main Types

Type Pros Cons
Analog 5.8 GHz Low latency, cheap, simple, light Lower image quality
DJI digital FPV High image quality, integrated ecosystem More expensive, heavier hardware
Walksnail Avatar Digital HD with many form factors Ecosystem-specific hardware
HDZero Digital with racing-focused low latency Image quality and penetration depend strongly on setup

Selection Factors

  • Latency: racing prefers very low latency.
  • Image quality: cinematic flying usually prefers digital HD.
  • Weight: tiny builds may need analog or lightweight digital hardware.
  • Range and penetration: antenna choice and VTX power matter.
  • Cooling: digital VTX units can overheat without airflow.
  • Betaflight integration: VTX tables, SmartAudio, Tramp, or MSP display port may be needed.
