I ordered 8 more batteries, a charger and some other stuff from HobbyKing. What arrived a couple of days later was a motor and an SBEC.
They sent me someone else's order.
So I contacted them to get this sorted out. It took them 15 hours to respond to the message I sent them; this is because they have a customer service disaster going on. What happened, is they've been sending Lipo batteries by air from Hong Kong and they've been told that they can't do that any more. And a large number of their orders included those, so sorting out that mess is consuming all their customer service resources. My stuff is coming from the UK, so isn't affected, but I'm caught up in the overall customer service resource bottleneck.
Eventually, I got a reply. I have to send the wrong goods back to them (fair enough), they'll then give me either a refund or a credit note, and I'll need to place my order again. I'm guessing it'll be at least a couple of weeks before I see the stuff.
