- Specs: rc_protocol: ExpressLRS 2.4 GHz (built-in module) + CRSF; supports external modules, tx_power: ExpressLRS up to 250 mW internal (100 mW typical), channels: 16 channels via CRSF; 12 channels stick + AUX, protocol_compatibility: ELRS, CRSF, Crossfire (external module), Multi-protocol (external), gimbals: Hall sensor gimbals (long-life, no pot wear), display: 1.9" 240x240 color IPS LCD, firmware: EdgeTX (open source) — model setup, mixes, telemetry screens, usb_type: USB-C (joystick mode + charging + sim)
- Verdict: The right first FPV radio — gamepad form factor lowers the entry barrier, ELRS built-in skips the external-module rabbit hole, and EdgeTX handles every FPV protocol you'll meet.

### RadioMaster Boxer
- Chip: STM32F407 | Manufacturer: RadioMaster
- Specs: rc_protocol: ExpressLRS 2.4 GHz (built-in) + CRSF + 4-in-1 multi-protocol module on some variants, tx_power: ExpressLRS up to 250 mW internal; external module via JR bay up to 1W, channels: 16 channels via CRSF; 12 channels stick + AUX, protocol_compatibility: ELRS, CRSF, Crossfire / Tracer (external), Multi-protocol (external), gimbals: AG01 Hall sensor gimbals (premium 4-bearing), display: 128x64 monochrome LCD with white backlight, firmware: EdgeTX (open source) — model setup, mixes, telemetry screens, usb_type: USB-C (joystick mode + charging + sim)
- Verdict: The right upgrade from a Pocket once you outgrow internal-only ELRS — premium gimbals + the module bay make it the do-anything FPV radio under $200.

### DJI O4 Air Unit Pro
- Chip: DJI proprietary SoC | Manufacturer: DJI
- Specs: video_system: DJI O4 (4th-gen digital HD, 5.8 GHz), output_power: Up to 1.6W (region-locked: 25 mW CE, 700 mW FCC, 1.6W when unlocked), latency_ms: ~20 ms end-to-end (claimed) with Goggles 3 / Integra, resolution: 1080p @ 100fps with 4K 60fps onboard recording, range_km: ~13 km FCC, ~6 km CE (line of sight, ideal conditions), frequency_band: 5.725 - 5.850 GHz (channel bandwidth 10/20/40 MHz selectable), camera: Integrated 1/1.8" Starlight sensor, 4K 60fps recording (RockSteady stabilization), microsd_slot: microSD up to 1TB for onboard 4K recording
- Verdict: The right VTX if you already own DJI Goggles 3 / Integra — best-in-class image quality, but you're locked into the DJI ecosystem and region-locked TX power.

### HDZero Race V3 VTX
- Chip: HDZero proprietary SoC | Manufacturer: HDZero
- Specs: video_system: HDZero (low-latency digital, 5.8 GHz), output_power: Switchable 25 / 200 / 500 / 1000 mW, latency_ms: ~8 ms glass-to-glass — lowest in the digital VTX category, resolution: 720p @ 60fps (optimized for low latency over high resolution), range_km: ~2-4 km typical race / freestyle line of sight, frequency_band: 5.658 - 5.917 GHz (8 channels, race-band compatible), camera_compatibility: Runcam Phoenix HD camera (sold separately) or HDZero-native cameras, input_voltage: 2S - 6S LiPo (7.4V - 25.2V)
- Verdict: The right VTX for race builds — lowest latency in digital FPV, but skip for cinematic builds (resolution is intentionally capped at 720p).

### BetaFPV Cetus X FPV Kit
- Chip: F4 FC + BLHeli_S ESC | Manufacturer: BetaFPV
- Specs: frame_size: 2.5" 95mm wheelbase (Cetus X frame), skill_level: Beginner — designed as first complete FPV setup, weight_g: 76 (without battery) g, kit_includes: Cetus X quad + LiteRadio 3 transmitter (ELRS) + VR03 / VR04 box goggles + 2x 450 mAh batteries + charger + spare props, motors: 0802 22000KV brushless motors (x4), recommended_battery: 1S HV 450 mAh LiPo (2 included), flight_time: 3-4 minutes per battery in typical freestyle flying, prop_size: 40mm 4-blade (BetaFPV Gemfan 40mm props)
- Verdict: The right first FPV kit — buy the Cetus X, fly it for a month, then build a 5" quad with the SpeedyBee F405 V4 stack.
