The Walksnail Goggle X Extension Board arrived just in time for me to try flying an analog tinywhoop quadcopter that (hopefully) will be easier for a beginner to manage in a small back yard. I don’t have much to add about it, especially now that “real” reviewers have had time to give their opinion, but one point I think that they consistently forget is that the double-sided adhesive pad supplied with the module makes packing the goggles a total pain and (I think) should be avoided.
Self-adhesive heavy-duty Velcro strips are an obvious win here: you can set up the extension board, VRX and antennas as a unit (I zip-tied my VRX to the module so that it doesn’t pull out in transport) and attach/detach the whole unit with the Velcro. It isn’t a perfect contact area because the curves on the top of the goggles, but the Velcro strips do their job just fine. Apart from that, as the reviewers say, the extension board works fine with a Foxeer Wildfire VRX and there was really nothing to complain about given the Goggle X as starting point (so, no analog DVR)). I’m not picky enough about latency to notice anything worth mentioning and picture quality is… Well, analog.
Obviously, this would not be my first choice if I were looking for an analog goggle “daily driver”, but as a way of adding on analog video to a primarily digital ecosystem, it really isn’t bad at all. We can quibble about whether Walksnail should have designed a more analog module friendly goggle, but this isn’t bad as a “slap it on for occasional use” kind of thing.
