Sidewinder SC

[twisted8]

anyone having problems with this motor esc combo ?

heres my problem : (copied and posted this to a couple of places)

so i went out and bought one and put it in my hpi mini trophy. i ran it the 1st pack geared 14/87. truck was slow and every once in awhile it would cog and make a squeal noise and not move. i would have to get completely off the throttle to get it to go again. temps never got hot.could hold my finger on the motor for 10 + seconds.

so today i geared up 3 teeth. truck was faster but not omg faster.then it started doing the same thing, squealing noise and then i would have to get off the throttle to get it to go again. so after 5 minutes the truck stopped, no power, just steering. the esc thermaled and the motor was hot but i could still touch it (didnt temp it as i ran my other truck)...after the esc cooled i ran it again and it made the same noise but this time nothing got hot. i temped the motor after 4 minutes and it was 120.

i have to call castle to see whats going on, im not sure what that noise is. sounded like a seized bearing but this is only two runs, not even complete runs.

any one have nay ideas ?

...................

i talked to castle today and the tech said sounded like something was wrong with the motor. he told me they would send one out to me or if the local shop had another in stock they would send it to them so i didnt have to wait if the shop was ok with that and they were.

ill get this one in the truck and give it a whirl.

well i got it together and went out today. 17/87 and it never got hot to where i couldnt touch it for more then 2-3 seconds and when i did temp it it never was above 120 degeress(motor) .the problem i have with temping mine is it takes so long to get the duratrax temp gauge in a place to read the motor temp it starts to cool down.with the cage and body its pia. so for now i am using the "touch" method.iam also not running the fan as there really is no room.(hpi mini trophey)

now for that noise...the squeal or chatter... i did hear it with this motor too but only twice and not as bad.

truck was faster with the same set up, gearing and battery just different systems (both cc sidewinder sc systems) so there was something wrong with the 1st one for sure...the second one with the same noise ? idk is this noise normal ?, is it a cogging noise ?(none like i heard before, coggin is usually a stuttering and a low ringing noise.this is a squeal.

on the truck i did notice the rear bearing on the gear box, the one that sits in the aluminum and is held in place by the top gear cover(its on the shaft with the spur and slipper) looks like it is spinning in the case, like the case isnt tight enough. the bearing isnt seized and i dont see how this can cause the truck to stop..

idk, its got me scratching my head. what your guys thoughts ?
