501x ball cup problem
 

anyone recomend a good set of quality ball cup ends for the turnbuckles as the standard ones cost me time during the racing last night when they popped off 3 times :mad: and a link to a good supplier please

neil i no serpent do good ones

yeah i know just thought there mite be another alternative as cant seem to find serpent ones

kirky said bout em didnt he :D

Have you tried the new Tamiya ones?

51283 5mm Heavy Duty Adjuster - 8pcs

whos selling them m8 :confused: are they from tamiya site

Try http://www.racingfactory.fi/shop2/ca...ails.php?p=850

btw if the Kyosho cups fit they'd be the best I think..

I've got the Serpent ones on my 501X right now. With the kit turnbuckles though there isn't a heck of a lot of rod in the rod end. I might switch over to some B4 titanium turnbuckles for the extra length - but the short serpent ball cups don't give a lot of adjustment.
I gave the car an immense beating and the ball cups never jumped off.. they aren't a direct fit though and have a bit of friction unless you are careful - so not ideal.


On woodys car this weekend I tried some Hot Bodies D4 ball cups - but they are a smaller size and need HB ball studs too. But he didn't have a failure and they seem a good fit with the kit / kanzen ti turnbuckles.

were did you get your serpent ones from jimmy :confused:

Elite Models / Elite models in Halifax is the UK Importer - but I'm sure other shops can get this stuff. I will post a few words on them soon maybe :) They are good, not ideal - but then I've not found anything that is yet. The Tamiya ones are good for a couple of meetings, then get progressively worse.

I'm using RPM bal cups. Had to change the ball studs to Schumachers

I use the ball cups from the RB5 Ultima on my car - no problems since I fitted them, plus they are the same size as the original ballstuds so no need to change other parts :)

ive got some white losi ballcups but need some ball studs with the same thread as the tamiya if anyone knows of any ?

have you the part number for these ?

Schumachers use a metric thread. That's what I used anyway

I have them in stock.

so i gather these below are the the kit ones :confused:
Tamiya Low Friction 5mm Adjuster (8pcs)
[53601]

Seems like they are identical to the kit ones??? :wtf:

Or not???

UM112 4.8mm Ball End. I have just ordered some from RC Champ along with a load of other goodies... :cool:

Ahahah, those Tamiya ball cups are so crap! I popped them off twice today and did NOT even hit anything.

I'm going to order the Kyosho cups..

Are these the Losi ball cups Hupo Hönigl was using on his 501X: http://www.losipartshouse.com/servle...ty-Ball/Detail ?
Do they fit the stock turnbuckles of the car?

yes and yes - just remember Hupo was running yokomo ball studs, I think Hotbodies would work also though.

When i use a Losi ball cups.
Do they fit the ball studs of the car?

Unfortunately no.

You will need Schumacher, Yokomo, or HPI Ball studs.

Are these the correct HPI ball studs??

4,3x10,3mm PRO4

Thanks

HPI Ball studs can i use a Ball studs for D4?

thank you

I am using the d4 studs, though I'm using d4 cups as well.. but the losi cups should fit though I've not tried.

Hi Jimmy,
I'm thinking of following your example and buying myself the HPI Heavy Duty Ball Cups and the ball studs for the D4. Does it require any modification to my TRF501x parts? Thanks in advance.

no, the only thing I noticed though was the ball cup on the inside hole on the rear camber link - the HB ball cups will slightly rub on the chassis, it's only slight though so you can either sand them down or leave it.. I left it.

Other than that, I think it's all good. I won my first regional today with the HB stuff on. I am using B4 turnbuckles but the kit ones will do the same job.

Thanks Jimmy!
And congratulations on your win :D
Oh yeah. And thanks for this awesome website.
It was your articles that made me get the 501x as well as the nosram matrix evo 2007.

Im running the grey Schumacher ball cups but I also use the Schumacher ball studs too.I wasnt happy with the original tie rods so I opted for some tungsten items aswell.Never had anything come off yet.

The Kyosho ball cups are a direct fit. They feel very free, but I've been racing with them for 3 weeks and haven't had one come off yet.

Since i started this thread the buggers havent popped off since :D how ironic is that ....
