Also, just because everything is new doesn't mean you may not have a faulty product. If you can, I would start with swapping out the receiver and testing, and then swapping out the ESC and testing (not at the same time, one at a time to see if one fixes the problem). I don't know where you are located but you may have someone local that will let you borrow an ESC for testing if you don't have another vehicle you can borrow from...
