VTX Performance
Here you'll find a summary of all my VTX testing data as well as links to the best performing products in my testing (affiliate policy). Access to the full database of test data is available to my Patreons.

Best on Test
Foxeer 5.8G Reaper Infinity 5W 40CH 5.8Ghz VTx
5W of output power for the maximum possible range on 5.8GHz. Foxeer also do a 10W version (only available direct from Foxeer). It supports up to 8S input voltage and has a 5V output for the camera. It's not legal to output more than 1W from a drone in the USA so bear that in mind.
Avatar GT VTX
The Avatar GT VTX delivers a ridiculous 2W of EIRP output power across 2 antennas. This is the most powerful Avatar VTX to date and is perfect if you're looking to fly long range or need a VTX with the power to punch through obstructions to give you clear video.
Foxeer HDZero Race VTX
Foxeer made a HDZero Race VTX! I actually prefer the specs of this VTX to the HDZero one because it can be powered from up to 6S LiPo voltage! Everything else is the same as the HDZero Race V3.
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.
iFlight Blitz 1.6W VTX
1.6W of output power in a compact package makes this analog VTX suitable for 5"+ drones. At maximum output you can get excellent range with a quality omnidirectional antenna on the drone and high gain antennas on goggles/ground station
Walksnail Moonlight Kit 4K Avatar VTX Kit
The top of the line Walksnail Avatar VTX. Onboard 4k60 recording and 1080p60 or 720p100 video in the goggles. The image quality is not as good as DJI O3 but the price is much more reasonable and this camera does better in low light.
Flywoo Naked O3 Lite
Slightly heavier than the Naked O3 Ultra this version is slightly cheaper and retains the shielding cans on the air unit for slightly better durability. You can remove these manually if you wish to get down to the same weight as the Ultra for a little less coin.
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.
Blitz Whoop 5.8G 2.5W Analog VTX
Don't let the name fool you this VTX is not for whoops! With a maximum output power of 2.5W this VTX will give you solid analog video out to extreme range when paired with a quality omni antenna on the drone and high gain receiving antennas on goggles or a ground station. The integrated fan helps prevent the VTX overheating before takeoff.
HDZero Race V3 VTX
If you're a racer then HDZero is the HD system for you and this VTX is designed for 3" and 5" racing quads. Make sure to use a flight controller with at least a 5V 1.5A / 9V 1A /12V 1A BEC. This VTX cannot be powered from battery voltages above 2S.
Flywoo Naked O3 Ultra
If you want O3 at the lightest possible weight this is it. All the O3 features you love in an ultralight form factor. This can be suitable for quads with props as small as 2". Just like Porsche the less it weighs the more you pay! Also consider buying the Naked O3 Lite and removing the shielding cans yourself.
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
