No Response From Brushless Motor

[Dave31]

Decided to change my motor from brushed to brushless in my M05 yesterday and I am now wishing I had'nt! I'm running out of ideas so if anyone can offer some advice it would be much appreciated.

I put a 13.5 Speed Passion sportsman and hooked it up to my hobbywing xtreme stock esc and when I turn everything on all I get is a constant tone from the motor and no response when I try to excellerate although the red light comes on the speedo however it does not seem to pick up the end point of the acceleration as it does not show a green light. I have checked that the motor is ok by hooking up a robitronic brushless to it and that works fine, so I have updated the firmware on the xtreme stock to make sure that is ok and I have no problems plugging in the program box and changing the settings. the steering works fine. I am guessing the speedo has died. I am hoping I have missed something simple, any ideas?
