Just the luck of the draw sometimes.. anything can fail

does it do it if you take the motor out of the car also?

This happened with my son's Blitz. It turns out it the Lipo cut off. Are you using Lipo or NiMH? Check the Lipo cut off on the esc.

if you are using nimh batteries with a lipo cutoff, could def be an issue. If your using lipo, the cutoff should be 3.0volts

will have a look now thanks guys sorry just got bk in i had to pop out for a few mins

how many cells are your running and how many turns is that motor

yes i'm using lipo the low voltage cut off threshold was set at 3.2v/cell so i changed it to 3.0v/cell but it hasnt helped any

2 cell 5300mah 7.4v lipo nano-tech - 7.5t 4460RPM motor

did you change any of the default esc setting or the motors timing?

i've set all of them back to default i did not touch the timing its set at 15

i might be time to take the motor out and blow it out. make sure you note the timing position and take your time. I had the same issue once, I took the motor apart and cleaned it, put it back together and made sure everything was tight. and it worked fine. also, make sure nothing is loose. I had a motor once get a loose timing adjuster and it was at like -120 deg timing and it didnt work from crap. I readjusted the timing and it was good.

Ok thanks for all your help guys am going have to do abit of research on the motor before i take it apart & clean it. i will let you know how it goes... Thanks again!

how long ago did you buy the esc? still have a warranty?

the 6th of may not sure about the warranty umm...lol how do i take my timing position i've got no compressed air but i'l give it a brush and a blow will mine be as easy as youtube.com/watch?v=JoLT1ZUE7Ig&feature=related that?

well timing is different from motor to more. some use those 3 long screws that can be screws in 3-5 different positions. Some are on the end of the motor near the 3 wires and is held in place by 3 screws. normally if the screws are loosed, you can rotate the timing on the end. take several pictures of both ends of the motor. and use them as a reference when reassembling. you can also video take your disassembly and the use the video to reverse your steps.
