Have been lurking in your forum for some time now. I decided that I needed to join as I have many questions. I am a 107 pilot and I have the P3, P4P+, and the Inspire 2. My interest is in inspections. Everything from cell towers to solar panels and even roofs. Finding that these DJI units are not going to fill my need and I don't plan on spending upwards of $35,000 for the new M210 RTK with the Zenmuse XT and Z30. I have been waiting for the release of the H520 but I'm beginning to wonder if they have changed their mind. I guess the H920 Plus would work just fine, but I guess the CGO-ET doesn't fit it. I also am having a hard time trying to find out if the V18 Zoon would fit as well. I know they have the CGO-4 that is a 3x zoom, but I don't know if that would be enough. All these questions at my age can make one dizzy. Thank you in advance for any answers.
