new here, but my 4-tec is grinding...?
Hey all, im new here. But got a question...My electric 4-tec has been making this odd grinding noise lately. What started it, i was running it around in my friends driveway and he had a plastic lawn chair up, he distracted me for like 1/10 of a second (i swear thats all it takes) and my car went straight for the chair, and crash right on it.
So since then, it's been making this horrible grinding noise in the rear of the car, but i cant tell if its the drive shafts or the motor or what? In addition to the grinding, it maxxes out at about 10 mph since then. Pretty much its just slow and grinding.
What's the problem? Anybody?

um yeah the 4-tec
i would say check the gear mesh. i had the same problem with mine . but here is the thing the two stock gears on my car will make a grinding sound. and ive messed with them alot to get it to stop.. but it dont . now ive put on a new spur gear and it went away. or i can use the old spur with a new pinion.. so the stock pinion and spur get put back on the car and the sound comes back..... if that dont help just remove all the screws from the car tilll all you have is a pile of parts. then clean them all and put the car back together. yull need the practice!!! ive had my 4-tec about a year now and broke every part at least once. but i drive it hard and put it a way wet .

Thanks for all the advice guys...this weekend i'll dig my 4-tec out of the burroughs of my garage.
haha since i've moved, it's been kinda of "disorganized" if you will.
Also, just so i know my car better, it has these two little white bars, and over top of them is a blue anodized casing. I think my stampede had this when i had it...can't remember. What is it? Heat sink?

resisters...right...and they do what?
#13
resistors are used to drop voltage on my esc i plug in a 7.2 volt batttey but after the esc im only getting 5.2 volts so on your sc those must be doing the same thing why there is a voltage drop i do not know
