What did you break today?

[djrahbee]

Exploded rear diff case on K8. Looks like it shares diffs with rtr and oc. First for me. Just ripping around on dirt/gravel. No jumps.

Anyone seen this before? If so what do you think caused it? Looking at the HR metal diff cups. Vitavon internal gears.

No clue. Did you have a bad day at the greens and come home and beat it with you 9 iron?

Nah I played pretty good. I wasn't giving it hell by no means. I wasn't even EXB'n it! Maybe turned the punch up too much.

Ah...cool. Thanks for the links! Looks exactly like mine. Don't feel as bummed now.

@Hammer Down what cups did you end up going with, and gears??

Can’t remember what the census was.. but I think the Vitavon cups are the best solution so far.

Oops

You all know the price of running in fine dirt or sand. Inner wheel hub bearing locked up and melted inside of rear hub. Luckily had a replacement from last order. Will we run in dirt again?... absolutely!

Seen these yet? They're only 18/20 bucks. I got some Vitavons but saw those and was curious. Some guys have good luck with cheaper stuff and some say STAY AWAY.

 

[BashTillBroken]

not me but one of monster trucks at the show this weekend broke there rear steering (shameless) so I hopped the fence and took the bolt that broke
The bolt it bigger than I looks just got huge hands

 

[speeding_Infraction]

What part of the bolt is that? Not seeing any threads

 

[BashTillBroken]

It where it sits on a bearing I believe here you can see the thread a bit better

I have not seen those yet. The cheap stuff is a gamble…

So I setup the backyard track and decide to go for a race with my 11 year old. Then she decides to play bumper cars. The Trophy Rat has a broken front arm (If those are the same L & R I have a spare) and her Rustler has a broken shock, again, this time they were aluminum shocks and still she killed them. My little girl is quite the thrasher.

 

[fozzy71]

oops, well-done traxxas i guess ¯\_(ツ)_/¯

 

[Notorious J]

Was hearing a funny noise while blasting the Kraton today. Thought I had blown a diff or maybe a drive cup. Nope. Turns out the RPM arm was bending out of shape and the noise was the cup digging into the arm. Bye bye RPM, that's the last time I watch you bend out of shape and ruin a run

Dang! That sucker is seriously deformed!!

Same. Just yanked the ones off the front of mine last night. Broke the rear ones about a month ago. Back to all stock arms now.

What has happened to RPM quality? 10 years ago we swore by those arms on our big and heavy Losi 5th scales. Now all I hear is negative.

 

[jkflow]

That is standard RPM quality, they bend out of shape just being installed, but it takes several months.
You can always toss them into cooking water and they straighten out.
