There is a new Huoniao Owners Club (http://www.huoniao-owners.co.uk/). Although the web site is still under construction, large parts of it are operational and you can register etc.
Aimed specially at the growing numbers of owners of Huoniao/Hoatian HN125-8 and simliar clones such as Lexmoto Vixen. A useful place to import tips from into this forum!
