Hello,
Is it worth upgrading my fatshark attitude v2 (quite old but work ) to some eV100? I just saw them on second hand for 50. Is that worthwhile? Or should I wait to get something actually good?

I wouldn't bother. They wouldn't be any better than what you have, smaller screens, slightly better resolution, no diversity. Good as a spare set though, or for someone else to see the flight with you. They do have focus adjustment so helpful for people that don't want to spring for diopters.

The reviews I saw of the EV100 were mediocre at best. I echo what Sugs said. I would save your $50 for something else and just stick with the FatSharks. At least you can still get service, support, and parts for them if you need it. Try getting any of that with the Eachine goggles

Okay, thanks for the suggestions, i won't get it.

hello, i bought EV100 about one year ago, are really bad, fov is really small, haven't real diversity but only one receiver and switch from one to other antenna. But i think the most real problem is FOV. For real money wasted ,for example my old ev800D are really cheap but better.
