Lightweight VTXs & Cams
HDZero Whoop Lite
A smaller and lighter version of the HDZero VTX. It uses a super lightweight camera and runs on up to 3S battery voltage
Happymodel ELRS Fyujon AIO Board - 5.8GHz OPENVTX + 2.4GHz ERLS RX
An all in one 300mW VTX and ELRS 2.4Ghz receiver. If your flight controller doesn't have this build in it's a great solution for tiny drones and weighs only 2.1g!
Walksnail Avatar 1S VTX
A smaller and lighter version of the Avatar VTX. There is a version with the standard Nano camera and a LITE version with an even lighter board and camera. It only works up to 5V though so you'll need a 5V 2A BEC if you're running 2S batteries!

vtxs & cams
HDZero Freestyle V2 VTX
True 1W output power for the HDZero system just got better. The smaller 30x30x14 mm form factor and 20mm M2 mounting pattern make this VTX perfect for 3" - 5" Freestyle drones and pilots who want the lowest possible latency of any FPV system available today. De-cased the VTX can be used on Lightweight 3" builds.
Rush Tank Ultimate Plus 5.8GHz VTX
A solid choice for Analog with a high transmit power and good reputation for reliability.
Caddx Vista / RunCam Link
The Caddx vista is a great option for DJI pilots who prefer to record their HD footage on a Go Pro.
Avatar V2 VTX
The full size Avatar V2 VTX comes in two versions: 8GB and 32GB of onboard storage. You can also choose between the Standard camera (best for daytime flying) or the Pro camera (best for lowlight flying). With better image quality and features than the Caddx Vista at a lower price, this is a solid recommendation.
HDZero 1W Freestyle
The best range and penetration for HDZero with 1W of transmit power. Ideal for aggressive freestyle where the benefits of low and fixed latency are key.
Walksnail Avatar
The full size Avatar VTX offers diversity video transmission and 8GB of onboard recording as well as supporting up to 6S input voltage.
HDZero Race V2 VTX
HDZero offers unparalleled performance for racing and competitive freestyle flying. This VTX fits on 20mm M3 mounting which is the standard for racing quads. The 200mW output power is modest but most racing events limit output power to 25mW so this isn't a serious limitation.
DJI O3
The DJI O3 system pushes digital FPV in a new direction. Here the focus is onboard recording and image quality at the expense of latency. It is a great looking system, some pilots are reporting issues with vibration sensitivity of the IMU used for electronic image stabilisation, hopefully this will be resolved in a future firmware update.
RXs
Happymodel ExpressLRS Nano 2.4GHz EP1 RX
Happymodel were the first to bring out ELRS hardware and their EP1 and EP2 receivers closely follow the developers reference design and are incredibly tiny. I lean towards the EP1 as the UFL antenna is much higher performing than the ceramic antenna on the EP2. If you need the smallest size and weight the EP2 is also a great choice.
MATEKSYS ExpressLRS 2.4GHz
I've made my mind up. I'm only recommending ELRS moving forward. At this point it does everything better than any other radio link. LoRa for range and penetration, yes. 1000Hz update rate for crazy low latency, yes. Loads of manufacturers are making receivers for ELRS and I think this diversity offering from Matek is certainly among the best performing and most reliable.
