In truth, Speed passion is the main brand and OEMs to Hobbywing. Hobbywing provides Speed Passion with quite a bit of local R&D, just like we do for Speed Passion, but from several thousand miles away.
We at Schumacher USA are the US exclusive for Speed Passion, and therefore are not only aware, but we have some say as to what comes into the states as OEM product while working so closely with Speed Passion.
You can certainly buy Hobbywing directly from them if you wish.
