I looked at the site yesterday and didn't look for availability. Just checked again and it looks like you can hit the "Buy" button and see a price of $1,899.99 for the Color Box version. Living in CA the last thing I would want to do is order from a California shipper and increase that price by at least 7.75%, or $147.00.
There's a bunch of videos made with the Plus being made in the EU and UK now hitting YouTube. It appears Yuneec is again using dealers and early testers to generate the advertising. No issues with that as long as they are factual and representative of the consumer product release. So far things are looking good but I want to wait for Yukay to perform a full shake down of the one he's just received before making any serious considerations. Right now I'm also looking at Parrot's new Anafi drone as it appears to have a pretty good camera that swings 180* vertically that would be ideal for some types of inspection work. I don't like using a phone for a view screen though. The H plus is more than double the price but if good enough may be worth a buy in addition to round out field capabilities.
Something to consider and more info becomes available; as it's already been established the 580 can fly with H-480 batteries, will the Plus be able to do the same? If that's so then buying really expensive 580/H Plus batteries to roughly double mission duration might be a price versus performance consideration going forward. As we've found with the 920, there's also the possibility of finding standard lipos that fit the battery bay for a lot less money if one elects to modify the connection.
