RC best upgrade parts

[greg006]

I was looking in e bay and come across RC Best for origional thunder tiger upgrade parts. For example a tail case costs $50, this seems a bit cheap compared to the cost of a kasama tailcase which is about $90. I looked at the rather bad web site for thunder tiger which does not list any optional upgrade parts. I don't know if RC best sell origional thunder tiger upgrade parts. Does anyone if their parts are origional or stay away from RC best. the link is below.

Thanks for your reply,,, i should have been more specific. On the link below there is a place in tiawan which claims they sell genuine thunder tiger parts, they seem a little cheap. e.g. complete TT head for $159,, tailcase $50.. is anyone aware that this place sell genuine TT parts, or has anyone had dealings with them. The TT web site has no information on upgrade parts

I recieved a E-Mail from the manufacturer in tiawan. The parts are not genuine thunder tiger parts as stated on his ebay web page. They look the same but are copies.
