Couple of days ago,,I tried to buy lipo but,,can not,,live chat cs said,,"may be some problem" but still same problem. last night I bought planes and some parts except battery, it was o.k.
Only lipo battery buying is problem. Live chat cs said ,,Check in 24 Hr,,but it is already 48 hr passed. HK ,, you need to check your system. I think this is web system problem. check detail and make it happen.
