FPV goggles: matched to the video system, used within the observer rules.

What goggles do not change

No pair of goggles changes what the law requires of the person wearing them. In every jurisdiction below, the authority's own rule decides whether and how a pilot may fly from a screen, and no goggles are presented here as making a flight legal or safe. The rules are set out country by country, each in its own row.

Association rules sit on top of the law and are not law: the AMA's Document 550 (3 March 2021) requires a spotter next to the pilot on every FPV flight; the BMFA's Article 16 page requires a competent observer for general FPV flying, while racing in a cordoned-off sterile area under a race director needs no individual observers; for models under 2 kg or below 100 ft, section 8 of the MAAA's MOP066 (19 August 2019) has an FPV model flown by two members, with the observer able to take over at once. Detail is on flying with goggles and observers.

What racing rules ask of goggles

From the FAI's Volume F9, 2025 edition (effective 1 May 2025), class F9U. A 2026 edition exists and was not read; its effective date is reported as 1 January 2026 and as 1 June 2026.

• The goggle itself: the pilot wears a headset goggle showing the live video from the on-board camera and flies from that picture, with a mandatory helper beside them.
• Receiver and antenna: a competitor's own video receiver and antenna must be mounted directly on the goggles, no more than 160 mm above the goggle antenna connector; mast- or stand-mounted personal receiving antennas are prohibited (C.1.5).
• Both systems at the venue: the organiser's receiving system must handle analogue and digital transmitters and both LHCP and RHCP antenna polarisation (C.1.5). The earlier 2019 edition also had the organiser announce the video system before the event and let it require a type of transmitter antenna polarisation.
• Keeping them on: flying after removing the goggles, even briefly, is a ground for disqualification from the race (C.9.1); after a crash, the pilot removes the goggles to show they are out (C.7.3).

MultiGP's class page (read 30 October 2026; its Rule Book was not read) sets no video system per class. For its Pro Spec class the sources differ: the class page says any video transmitter is permitted, while MultiGP's Pro Spec page for the 2025/26 season says any HDZero or analogue transmitter and camera. The video system a race accepts therefore comes before the choice of goggles.

Analogue and digital, as sources describe them

Wikipedia (secondary, and carrying its own warnings for missing citations) describes a basic FPV system as an on-board camera and analogue video transmitter, with a ground-side receiver matched to the transmitter's frequency and viewed in goggles or on a monitor. Digital systems are described here only through their makers' claims, none of which was independently checked:

• DJI claim (31 July 2019): its first digital FPV system used eight 5.8 GHz channels, allowing up to eight drones at once, with 28 ms end-to-end latency and 720p video at 120 frames per second.
• DJI claim (current air unit specification page): a minimum latency of about 15 ms or 20 ms, depending on the air unit, in its racing mode with its own goggles, measured outdoors without interference. DJI lists only its own goggles as compatible, and notes that permitted bands and power limits vary by country and region.
• Caddx claim (24 March 2023): its Walksnail system has goggles with 1920 by 1080 OLED displays and a 46 degree field of view, and an average delay of 22 ms, on eight channels between 5.725 and 5.850 GHz.

The country's radio regulator, not the maker, decides which bands and powers may be used; see radio equipment rules.

The other half of the link

Goggles receive what a video transmitter on the drone sends. In the United States, the FCC (FCC 18-71, 5 June 2018) described these audio/video transmitters as intentional radiators that must be certified before marketing unless they operate only in amateur bands, and operating amateur equipment needs an amateur licence. The FCC's fact sheet of 7 January 2026 names data transmission devices and cameras among the drone components whose new foreign-produced models cannot get FCC authorisation since the December 2025 Covered List additions; models authorised before those additions can still be sold and used. No later FCC statement was read, so the list's state on 30 October 2026 is unconfirmed. See the FCC Covered List.
