I happened to chance upon these cloned 3DR Radios at HobbyKing while looking into the "DIY Electronics" section.
Really sad to see that they haven't credited DIYDrones / 3DR at all except a link to the wiki page. The have just coied the description from the 3DR website too. Being a staunch supporter of OSHW , I am appalled to see open-source hardware abused like this.
Their price is a real steal though, but not surprised since they take advantage of Chinese labour costs, etc. and spend no real development time on it or have any plans to give back to the community.
MinimOSD clones are stocked too : http://www.hobbyking.com/hobbyking/store/__31137__Minim_OSD_v0_1.html
They are stocking GPS modules which are not cloned from 3DR but are "updated GPS module that can used with ardupilot mega v2" : http://www.hobbyking.com/hobbyking/store/__31135__NEO_6M_GPS_Module.html
I will still support 3DR on this topic though, since they do the real development and give back to the community. Go 3DR!
