Now im sure all your RC fans out there have bought parts from HK. Its cheap, normally decent quality, but how often does it come late, or never at all.
I have found that if they send via HK post, with a tracking number, it always gets here within 5 working days. Often, they will choose the cheapest option, without a tracking number, and i only have a 60% succes rate of it actually getting here... So next time you buy from HK, ask for a tracking number, and if they wont give you one, ask for a postal service that does.
