velinion esc on LRP vector 4.5T sensored

[ThaMule]

I hooked up my LRP sensored motor to my velinion esc on a maxamps 2 cell lipo. When I power it up everything comes on fine but when I apply the throttle the motor acts as if it has a rev limiter on it at like 10k or 15k rpms. I tried it with and without the sensored wire hooked up and still got nothing. Anyone know anything about this? I call to traxxas netted me no results as they told me it was the motor. I said no, I have tried it on 5 different motors2 of which were new out of the package. Then they just told me I was out of luck. Please helps guys.
