Can anybody help me please! i am not very experienced and after months of waiting for parts and building i finally got it running...(Not for long Though )

Ok here is my problem i got my car up and running and it was sweet!!! but the second time i came to run it the something has gone wrong with the motor(i think) let me explain a bit better when pull the trigger the motor tryes to move but seems like it jammed it will jerk foward and backward but that's it. the motor is new and it's not seized it moves freely any idea's? i've got the dualsky track & field brushless car XM540TF motor & Hobbywing EZRUN-SC10 brushless ESC
ANY Help is greatly appreciated... Thanks!

check the wire connections/solder points from the esc to the motor

i have checked all the solders for loose connections and for possible arching but that does not seem to be the problem... thanks m8

Possibly broken or disconnected sensor wire.

Take the motor out and make sure it will spin free, you will feel it move in clicks or notches as the magnet turns and the poles kind of push and pull, it will be smooth and silent though.

Also check the drive train with motor out it should be free and smooth as well.

If the problem is not mechanical then the next thing to look at would be electronic issues.

That too, I have had them look like they were in there and just not be seated well... The wire is cheap as well and something to have a spare of anyway. Get a new wire to work into testing as well.

My motor feels fine the same as it was when i put it in i dont really want to open it and mess with the internals because am not that experienced but if i must i will... like i said it worked perfect the first time i ran it i'm thinkin it maybe sumet me m8's messed with on me transmitter maybe? my motor and esc are both sensorless

can you make a video of the issue and post it?

I shall get straight on it. Will i be having issues posting the video/url? just saying with me being a noob to the forum n all... i'l cross that bridge when i come too it anyway lol

If you can not get it to post the forum (a very possible issue since you just signed up and are up to 4 posts right now). Then just put it on youtube and somebody here should be able to help with a link in this thread.

put it on youtube and link it.

its is probably your esc or motor. being sensorless, that removes that issue. That esc is a 60amp esc. and your powering a 4x4 of some sort. do you have a friend with a brushless motor you can try and hook to the esc?

i dont the only other person that i know who is into rc runs a brushed system and my esc is the SL569 70A version

i just dont understand how it can work perfect then just mess up like it has...
