I have had similar bad experiance with them. I got a Aplus 400v2 on Ebay with Buy now. was supposed to ship in 3 days.
2 weeks past with lame excuse about having assembly problems. I was under the Impression that they had the kit ready to go!
Seems like they don't get anything until they have your money.
The Email was 2-3 days behind my questions most often they answered 1/2 of one question and did not respond to the others.
English was real poor.
If you want to deal with a Hong kong dealer try Eddie Wu at Flying-kit.com he is great! good email, Fast , honest , good english
Last order with Rc-expert the parts that were shown as in stock ...Paid for them and then was informed that they would not have them for 2 months .
On the status of my order on their web site said ( success ) I told them this added insult to injury as the only success was they had my money and I had nothing.
If you do order from them make sure to inquire that they do have the parts in stock and ready to ship before you send the money!
Rc-expert said they could not get the parts for 2 months i wrote Eddie wu and he sent all the parts on my list the same week.[&o][:'(]
