Do not ever buy in hobbyking!!! They tell people they have item in stock, then they contact you by email to tell you that they actually do not have the item in stock, and then give you "bonus points"!!! To buy in their website!!!.
Moreover, the live chat takes more than half an hour to give you some unuseful reply, they have technical issues quite often.
It took them more than 2 weeks to prepare the order for shipping!!
