Upgrading from Caddx Vista and DJI 03 air units. The 04 is a great step up from the 03 when flying in sunrise or sunset lighting. The 03 sucks in anything other than great light - the Caddx Vista is good with a Nebula Pro camera, or a Polar Starlight camera in near pitch black lighting but the 04 is better overall across the lighting range. Been flying quads for 13 years or so, from Analogue through to 04. I might just buy another one to pop in another frame.

The image quality is just amazing, compared to other HD FPV systems, I also find the range to be much better compared to some of the other systems, this is my first time using the DJI FPV system and I definitely don't regret the change so far, at least for my style of flying, these are great. The downside is when you get a signal loss, its very disconcerting when the image goes static, other systems which break up the image you can still roughly see where you are. This has to be the worst part of the system but the penetration is so good that the image break up is much rarer. If you are after a high quality image in both the goggles and the DVR which is very close to an action cam without the additional weight then this is the system for you. I know the race mode is supposed to bring down the latency but it also brings down the image quality so I’ve not used/required this mode yet.

Ok

Came as described

Can’t fault it!!!

the goat in FPV transitions systems. I've knocked a star off for the camera size as it doesn't fit into a lot of older frames, but for what you are getting it is worth the pain, nothing else compares to the quality
