After more than a month, since my initial attempt to email them, I received a reply and instructions on receiving the 'free' sample motor from Pulso/Danlions.
I tried from all my email addresses (5 of them) and got bounce messages from one or two or simply no reply at all. I then started searching on the various electric forum sites (RCGroups, RCUniverse and Wattflyer.com). Eventually, a sticky thread on Wattflyer started by "Pulso Systems" came up and I joined that forum/thread and made a couple of posts and a couple of PM's to Pulso Systems. Unfortunately, it seemed that Pulso Systems had abandoned their own thread, and stopped posting, even before the Sept. 15th deadline had been reached.
Then news that the Danlions website had extended the offer to Oct. 15th was posted, but still I got no answer to my emails or PM's.
I had finally given up, and decided that there was some hoop I wasn't jumping through or the Chinese government was fouling up the email or something when suddenly, I got a notice that I had a new PM at Wattflyer.com, which turned out to be instructions on who to Paypal the shipping charges to.
So I've Paypal'd them $20 for shipping of a '2826-10' (numbering appears to mirror the Axi line) - which is not really out of line for shipping from Chinese sources.
The other Wattflyer users who have reported contact and Paypal' ing funds have begun to receive motors, kind of out of the blue - no shipping notice or tracking numbers and there is no real limit to what you can request, as far as motor sizing, although they are reported to be "out of stock" on some sizes.
So, we'll see if something turns up in the mail, now. I'd like to fly it yet this fall and if I do, I'll report impressions in this thread.
