Actually I think it's very valuable for people like Alex to share experiences just like this. Clearly there was some fault with the Solo that caused it to lose signal, but maybe it was out of range or something else. But he's not blaming the Solo....just sharing.
Solo has SO many features that like RTH and SmartShot that make it so easy for anyone to fly it. But it's still SO important for people to understand how these features work, and what type of possible unforeseen consequences there can be from using them. Heck, when I first got mine I had NEVER flown ANY drone before, and within an hour of opening the box, I was up in the air. But I lacked any basic knowledge of how to fly. I let Solo do it all. In hindsight I was lucky that I never had a bad crash. Now I've spent some time in open areas flying in Manual mode, trying to learn basic manual flight, but I still suck! But when it comes to using RTH or any of those features, I understand how they work and what could possibly happen if there's obstructions in the flight path.
I honestly think that a large part of the complaints and bad press we hear about Solo is because of uneducated pilots. People who rely too much on the autonomous features but lack the basic knowledge of how they work and how to control the drone without them.
