I saw by coincidence this website:
The prices looks extremely low and they even claim to have APM2.5.2... is that a scam? anybody purchased there before and can give some feedback?
lol... you confirm what I was expecting...
I bought something from this site before (a video receiver module). It worked without problems and was delivered quickly. It cost only 7$ so I risked it.
I own this http://www.rctimer.com/index.php?gOo=goods_details.dwt&goodsid=818 and the 3DR one, and they are identical. The both work just the same.
