Default anyone seen carnage like this before?? (pic)

so i bought a nitro stampede 5 days ago... got the itch for more power (yea i know the stock motor couldnt even keep the front tires down i just wanted MORE ) anyways i ordered part number 4400 off tower hobbies and i installed a new 2.5r on it, broke it in, and when i started really thrashing on it, all of a sudden it locked up and i heard grinding. so i was like uh oh the diff just exploded or i stripped a spur... i go over to the truck and the spur was fine. then i made sure the axle shafts were still tight onto the yokes, and they were... yup my diff is junk. so i pulled it apart (there are 3 main gears) they all looked fine!!! WTF!!?!??! so i pull the big axle gear out (the one with 4-6 metal gears inside it) yup they were all shreded... wow this really bums me out because i dont know of an upgrade for it!!! i guess ill just order a new one...

Looks pretty clean other than the one broken gear. I was hoping to see some serious damage..

I think the gear looks great. I'd say put it back in and do some real damage. Make it work replacing. You know..

Tear it completely up...



Just kidding....

It is too bad these parts are not made of some good old real steel and not plastic. or cheap compressed powdered steel.

When i was working at hobbytown usa last weekend.I had to fix the same problem.It was a rusler vxl tranny....and of course on 3s lipo with a newb.Well he didn't know how to control the truck i was guessing.These gears never have issues.Especially being brushed motors.
