Can anyone from Hobbywing tell me when the new Xerun XR10 Pro will be available for purchase in the U.S.? I sent an email to Hobbywing North America a couple weeks ago and never received a reply, and when I call nobody answers. I seen on the main website where it says it will be avialable end of the first week of April. I figured if that was accurate you would be available to pre-order them by now.
