Has anybody tried boiling the ball cups before running them? My kit is coming on Thursday and I was thinking about boiling before swapping ball cups.

I must be insanely lucky as my ballcups do not pop off at all. I had one come off this weekend when I broke a front A Arm but that is the first time I have one pop off. This is on a desc410r though not a dex210 though. On my DEX410 I used to have, I put the stock ball cups back on it after switching to rpm ballcups and not liking them.

I had trouble with those popping off too. It was mostly just the ones on the steering. It seemed to be mostly caused by the flex of the ackerman plate. I made one from carbon fiber and it seemed to fixed it.
Would everyone agree that the ballcups that are mostly popping off are the steering links? or is it randomly the whole car?

I have been running my desc410r for 6 mos and have not had a ball cup pop off, but front arms seem to pop off once in a while...

Somone just mentioned that it is the new HD style on the 210 with the issues.

RM 3 setup I swapped my rear hubs. and installed the ball cups so they are straight. Ever since that change I have not popped a ball cup in the rear. I also have not popped a front in weeks.... Allaignment on the ball cups is key. Pay attention to the natural float of the ball in the ball cup. And dont hit anything or bottom out.

I know it has been talked about on here, but what is everybody running as far as the balls and the plastic links go?
This is because when you build them to the correct length the ballcup actually goes over the non threaded shank of the link. You can do one of two things: trim/sand a small amount (1/8 inch or less) off the end of the ballcup or counter bore the hole in the end of it about an 1/8 to allow the non threaded shank enough room to rotate freely in it. Also, make sure to lube the threads before assembly. Ive been using black grease but chapstick or beeswax work well too.

Ive now had a good few hours with the car... orsm is all I can say.

Ball cups , Ive had a few pop off but all in all thats because I crashed or hit something. Make sure that you have them at 90* to both ball studs that they are connected to that way they have a little play.

When you build them use grease and if you can out one end in a drill and slowly drill them in and out several times. Even after this I may need to hold/press down on one of the ball cups with my fingers while adjusting them.

Diff, no problems here, build it right and run it in and enjoy, its still smooth.

I use the ace 1015, maybe a little overkill but made a difference as it weighs more than the sav÷x low profile
And I fited tamiya battery holders and reamed out the stock battery holder so now I can use body clips instead of thumb screws, really easy

But your servo could be next in line. Sketchy. I'm thinking plastic is the play.

As far as "something's gotta give/break", just from past experience, the force of an impact has to manifest itself somewhere.
I have fitted the Tamiya #51000 hi torque servo saver to mine. Fits nicely and is really precise. If it is good enough for the Tamiya 417 TC it is good enough for my DEX210
