HobbyKing has rebranded from just about everyone, from XRay to HSP, Nanda, Sakura, TeamC.. they've been all over the place, their X-Car ESC was definitely not made by SkyRC, some have claimed the X-Car was made by HobbyWing but with low quality parts which is why they haven't been as reliable as the HobbyWing branded products which they have also sold.
Looking forward to seeing what they will be introducing with these "28 new models", how many will be surface based and will they be kits or RTR?
Hopefully they continue to maintain a balance between quality and price!
