The funny thing is, raidentech.com, xheli.com, nitroplanes.com and I'm sure many other online RC shops all seem to be registered by a Jun Ma in California... I think this is too much of a coincidence to overlook. I would say they are definitely run by the same person. What is truly strange is that the prices are xheli.com seem to be slightly higher than the prices at raidentech and nitroplanes. This might be because the rep for xheli is slightly better than the rep for the other two. I have heard nothing but bad things regarding raidentech and nitroplanes. Raiden Technologies has a HORRIBLE BBB record, with 19 unanswer complaints and an F rating by the BBB. I wouldn't recommend purchasing from any of these shops and I would do a WHOIS search on any other site that looks like it might be affiliated with them just to make sure you're not getting jipped. I recommend
