so ive been running fatshark dominator v3s for like 4 years now and honestly they still work fine but everyone in my local group is switching to digital and im getting serious fomo watching their feeds. the clarity difference is kinda nuts when you see it on someones goggles vs what im looking at.

main thing im trying to figure out is whether hdzero is actually the move or if i should just go dji o3 and be done with it. i fly mostly freestyle, some light racing, nothing super serious but i do care about latency a lot. heard hdzero has better latency than o3 but the range and penetration through trees is worse? or maybe its the opposite, i genuinely cant tell anymore from all the conflicting stuff ive read.

also whats the deal with the antenna situation on hdzero ? do you have to run the specific antennas they bundle or can you swap in whatever lhcp stuff you already have. i have a bunch of axii antennas sitting around from my analog setup and itd be nice to reuse them if possible.

ran both for a few months before settling on hdzero for racing and honestly the latency thing is real. o3 is gorgeous but if you're doing anything fast or in a tight course you will feel the difference, its not massive but its there. for freestyle tbh either works fine and o3 image quality is just better period.

on the antenna question ? hdzero uses standard sma connectors on the goggles so yeah you can run your axii's no problem. just make sure you match polarization on both ends, rhcp on both or lhcp on both. mixing polarizations will kill your signal way more than any antenna choice. i run a pair of pagoda style omnis on my goggles and they work great for close-in stuff, switch to a patch for longer range cruising.

dude i went through the exact same thing like 6 months ago. ended up going o3 and have zero regrets but i also dont race at all so latency wasnt a dealbreaker for me. the through-obstacle penetration on o3 is genuinely impressive, flew through a parking garage once and it barely broke up at all which wouldve been static hell on analog.

the goggles themselves tho, the o3 goggles 2 are kinda bulky and the foam is mediocre. just a heads up if face comfort matters to you.
