Ball cups
 

I have managed to get my turnbuckle to disappear all the way into the plastic ball cup on the front. I wondered why it looked so strange and could not work out why the drive shaft was so close to the yoke. I have found that after a heavy crash the camber or toe is usually out and I am checking this after every race just incase. I was wondering what other people are using or if anyone else has experienced this.

Yes, the ball ends strip or push in on impacts and not just during crashes. I landed at an angle from a smal jump at a corner and stripped a rear camber link.

I also think they develop play quicker than other makes. I also never really had to be carefull before about which way round the turnbuckles were as if they are wrong they tighten with the suspension action.

I've ordered JConcepts ones to try next as the stock ones aren't available at the moment. I noticed in photos that the Team Durango world champs car has White turnbuckles that look like they could be the JConcepts ones.

Try using the white Losi ball cups and HPI ball studs, these are excellent and seem to stop the problems :thumbsup:

Glad you like my work Alec;):thumbsup:

LOL, i've only just finished taking both diffs out. I thought I'd better have a look and see how it all works :lol:

what size ball studs do I need to use the losi ball cups?

would the RPM rod end fit on the durango's ball stud ?

I would like to know this as well :)

Ball cups!
 

Guys do you have part numbers for these items (Ball studs and RPM cups) as my Dex will be here next week and I'd like to have all my option parts in hand by that time.

Thanks!

Yes the rpm trackrod ends fit the standard durango ball studs(be sure to buy the long version of the trackrod end though) i,ve just fitted mine allround and its taken all the slop out plus the rod ends are a lot tighter fit on the trackrods so i would imagine theres less chance of them moving.
The best thing is though they look totally sexy in white rather than black:p

Are these RPM ones the Super Duty Turnbuckles for Lunsford ball studs? I ask as I have tried some J Concept ball ends on the turn buckles but the ball stud is not big enough for the Durango ball stud and was horribly stiff.

They are just the standard version but a bit longer,The only thing i have noticed is that where the track rod end fits onto the inner durango ball end thats a bit stiff and does restrict the shocker movement but i,m hoping with a couple of runs this will free off

This was a problem which i highlighted to TD when i gotten the kit (1st few batches) and was politely brushed off by saying none others has had this problem. Anyway, you'll be safer with rpm ball cups with 4.3mm studs. The kit studs are a tad bigger

The Associated TC5 ball studs are the smaller "standard ball" but with Metric threads. I've been using these with the losi dark grey extra rigid cups with excellent results.

ASC31280 Short neck, 5mm thread
ASC31282 Short neck, 10mm thread
ASC31284 Long neck, 8mm thread
ASC31285 Long neck, 10mm thread

LOSA6016 Extra rigid ball cups GREY

I ordered these ball studs because I was told I only needed 8mm

Is this going to work????

Yep, either of those studs will work. The black are the short neck and the silver are the long. The long neck ones will have the same height as the originals so camber gain will be the same. You can use the short neck to play with camber gain or bump steer too.

The cups you have pictured there will work also, they are similar to RPM's plastic. These are the losi HD cups I'm talking about, they seem to be super hard compared to others. Either will work though :thumbsup:

Just for anyone that is interested the Losi and AE ball stud diameter is around 4.27mm I reckon this is why HPI use 4.3mm. Being of the 4.3mm type you can use any ball end that will fir AE, Losi or HPI. The Durango ball stud is 4.47mm which is more similar to Kyosho 4.5mm size. Currently HPI and AE TC5 ball studs have a 3mm metric thread and will fit the Durango holes.

Schumacher ball studs are 4.3mm so I have got some of these from M K Racing and am going to try them with some J Concepts ball studs. Pictures to follow.

Hey Guys,

With the problem of the ball cup, any one tried to put a drop of cyano in the ball cup to reinforce the plastic of the ball cup?

Thanks

losi/associated b/studs wont fit as they are imperial

Just get the newer versions of the ball cups from Durango and it should now be fine as they have made the whole where the turnbuckle screws in slightly smaller which stops it from jumping threads.

Correct as you need ball studs that have a 3mm thread like Schumacher, HPI and the ones from Associated for the TC5. Trouble is the ball diameter are then different as I stated in an earlier post.

Has anybody had any problems with the small ball joints ( servo link and roll bar ) splitting ? About half of mine (NEW 2010 spec) have split and the rest are showing stress marks :( Can anybody tell me a substitute that can be used ? part no's would be great. :)
All the other ball joints look good :thumbsup:

Yes, I had this prolem as well. I just built up a 2010 spec kit and ran into the same thing. I even tried reaming out the hole and they were still splitting open on me. Luckily I had some spares from an R kit.

I think the 2010 spec kit has better ends than the R kit for stiffness, however. You can even adjust the turnbuckle on the car, but I still haven't narrowed out the possibility that I will have to get some nitride balls from AE and those extra heavy duty LOSI ends.

Finding that the ball cups pop off on the 410R when I'm adjusting the turnbuckles.

Anyone else have this problem?

Yes I had the same problem with mine, it had it's first outing today and I was very impressed with it

ball cups
 

me too and loads of others
fitted schumacher balls and losi rod ends now works spot on.
i copied what a few other people had done

Hi,

What are the part number for the Losi bits?

Seen HPI and RPM mentioned too.

did you grease the thread before putting them into the ball ends? just a thought
Your car did look good ian, and drove real nice

They were already built as I got the car, new but built. I'm tempted to strip them down and re-grease / check!

I also use Schumacher balls and Losi rods (Losi A6016) they dont come off now!!

Don't suppose you know the part number? .May try and get some Core RC ones.

Have people changed them on the steering arms too?

Schumacher ball studs and Losi HD (white) ends and have had no problems after that. In fact found that the XX4 Lunsford turnbuckles work as great replacements for the Durango and are much cheaper! I have only done the camber links not the steering links.

Part number of the Schumacher balls do you mean? I had some U2722 left and the Losi ends A6016, I have only changed the steering ones as for me there the only ones that have come off.....

Got the prob with all of them, but going to strip down and grease and recheck in the mean time.

i had the problem with all of them too
i used the losa6016 ball cups and sorry don't know the schumacher number got them loose

I'm using Losi HD cups, and AE TC5 balls, (silver, and black), and have seen a definate improvement in performance, as well as durability. No stripping, no flex, no popping off. It's what the 410 is meant to be, now. I set the track record the first race after the upgrade. :)

Fabs suggested using Kyosho 97021H hard ball cup set, i am yet to get mine, will let you guys know how gud they are.

im using rpm ball cups long ones and schumacher ball studs


im trying to find a cheaper replacement for the turnbuckles

anybody know of any part numbers


thanks colin

Kyosho ones are a no go!!!!
