Their prices on X3 gimbal parts are also good, other parts not so good, both helipal and himodel are good for some parts on prices.
I've also seen centre frame components on ebay for ~$160 USD - they used to be ~$800 here in Oz and not much cheaper from overseas.
BTW - not an ad for these guys above, I just stumbled across tienda whilst looking for X5 yaw motors, they had them listed once, and I thought cool, good to know - I should have bought 20 because when I went back the items were no longer listed
