I urge everyone to boycott these cheap Chinese knock off's. We all like a bargain, but ultimately we will shoot ourselves in the foot. If the likes of Durango, Schumacher etc can no longer afford to design and sell kits then the game is over.
They are giving us all the rope we need to put a big ol' noose right round our own necks.
RebelRC has got it right, if you see one, squash it. Just be sure it isn't a real Durangotango, 'cause that would be awkward.
