501X setup discussion

[Fabs]

I'd use a TRF 415 if I were you

[trf14]

Does anyone know how the TRF501x pistons compare with those of a B4?
thx

In this post, you could find my set-up from the first French National, I'm sure this could help you for starting !

Good Luck

If you have a look on the oOple setup sheet I compare the pistons to AE B4 ones directly. I am not sure the hole sizes are a direct comparison, but they aren't far off.
Thats how I translated my BJ4we setup easily to the 501X.
The Machined pistons are not worth getting, they change the damping too much (too hard) over the kit ones.. so you need to readjust your setup to suit.

Hi all,

in terms of keeping the setup consistent, what kind of maintenence schedule would you keep on parts? I am thinking of:

axle bearings

driveshafts

suspension balls


I am asking because I am getting very close to a good setup now (putting a one way in has made the car soo responsive its transformed the handling) and don;t want to keep chasing if I could be losing out from not replacing the above?

Also, I have the option pistons (1.2) and damper rings in, and am running 30wt, is this a reasonable damping setup?

For those who are looking for setup, there is this thread and especially this post. You will find some base setups!

Also it will be updated soon!

Hope that help!

Hello all
Can anyone tell me what effects using the hopup steering has. How will long arms change the handling or short arms

Thanks
Stan

Somebody knows what the colors of the Tamiya springs mean? The kit has standard yellow ones... and how they are compared with those from AE.
I purchased a set of Tamiya Hop up springs with the following colors:

Red:
Blue:
Yellow:

Thanks

[B4james]

Springs are rated the same as their touring car springs

RED = Soft

YELLOW = Medium

BLUE = Hard

Hope this helps,

[delanobe]

Yes, thank you!

If somebody has the colors for the associated ones I'm set

Thanks

[B4james]

Associated springs going from softest to hardest,

Black 1.74lb
Green 1.90 lb.
Silver 2.10 lb.
Gray 2.33lb
Blue 2.55 lb.
Gold 2.75 lb.
Red 2.95 lb. ASC

Has anyone tried the Hop up shock pistons ?

[TRF_Tastic]

You wanna read Jimmy's post above number 145.

[stefke]

I've read it, but he essentially talks about the difference in setup with the new pistons, not their quality.

I find the stock ones a little bit inconsistant. Also, In the SETUP thread, I saw Hupo using the hopup pistons (With Kyosho springs )

[B4james]

I actually like the improved pistons, yes they are harder than the kit ones but that is because they actually make the oil go through the holes rather than around which allows for more pack.

You also have less issues with the seals leaking because they dont allow side to side movement. I also now run the rod guide kit and Kyosho X seals from the Ultima shocks, heaps smoother and dont leak so far.

Hey Jimmy,


We have a big title event in a week and a half in Australia on the weekend of the 11-12th of August and the track surface looks very similiar to the Euro track.

You mention that you will have Hupo's 501X set up to put up soon, any chance of this being before this meeting date?

[jimmy]

balls, I didn't bring it in to work - I will write it on my hand so I remember as I don't have a scanner at home.

The biggest difference I made to my car was to put in the original pulley configuration, big rear and small front - this really settled the car down especially at the rear. and that's what Hupo advised (and was running himself)

but yeah, I will get the setup online asap.

[delanobe]

So the front one way is a no no?
