Figured I'd let everyone know the Pixhawk Basic Kit is on backorder on the 3DR website. They never actually tell you until you've completed the purchase and finally submitted a help request to customer support. I've been waiting on a kit since May 31 and just got a response from 3DR that the kits have been on backorder. Up until that point my order only indicated ready to ship.
I imagine there has been a number of people that have recently purchased or about to purchase a kit. Be ready to wait with very little, if any, communication from 3DR.
Hope this helps!
