Will's Limitless Street Racer

[Will89]

Some new parts arrived

Some carbon fiber, titanium rods and ceramic ball bearings.
With the rods I save around 12g in total...
I also took my mugen mbx7 to check the pivot balls... And what a luck, nearly the same diameter but much less weight!

(left one is the mugen pivot Ball )
So I ordered 2 pair (E0160 if you want to know)
That should save around 25g!

And the last thing I could do before I have to go to work was changing the shock oils.
I try 700 CST in front and 600 CST at the rear. I think arrma used 2k in both, to thick for me.

BTW, I had many air bubbles in each shock... I hope I can do it better with vacuum

I hope I can start with the re ensemble next week

So, my 'chassis brace' is ready now...

The original one has around 81g with screws.
My try weights only 36g with screws and nuts and the weight is lower to the ground.
I used a 4.2mm thick carbon fiber plate and I have to say the chassis is much stiffer than I thought it would be but I think it has enough flex to generate good grip for the tires.

Now I think about printing some caps for these nuts because they don't look very sexy

The front and rear Diffs are also ready, for the center I try something else...

Looking good.
You could probably get away with 1/2 the screws and nuts that you have and still be effective. The quantity and spacing they have is necessary for plastic, but way different needs for CF.

So... a little update before christmas

My "roller" is done so far, I build a servo mount and I finished my Lipo holder.

The Lipo holder has around 67g

I think I can do it lighter if I relieve some carbon parts, but I want to finish it first as Version 1.0
I also changed the damper mounts in front and on the rear to mugen parts and changed nearly all nuts to alluminium nuts.
Here is the comparison between original and the mugen parts, but you have to rework them a bit.

So that saved me nearly 13g (for me, each gramm counts ?)

I also bought some 4mm Titanium grade 5 rods and shorten them on the right dimension to use it as hinge pin.

Here you can see how I shorten the body mounts for the Infraction

And the mounted servo mount.

So … at the End of it the most important question … what is the weight of it completely?
(At the moment I just can use a kitchen scales ?)

So, all in all around 525g … I am very satisfied with this result. (3.988g -> 3.463g)
With GRP wheels and some more modifications I think it is possible to reach 550g lighter than stock.

After the christmas time I went over to the electronics ...
And I can make some better pictures ?

I wish you all a great christmas time! ?

Great update!! Looking very good so far and very much surprised how much weight you have removed!

May I bother you for the name of those tires you have installed??!! Those honestly look like they would grip really well for some parking lot track racing!! Appreciate your time! Merry Christmas to you and your family as well!! Have good one!

Thank you, the tires are some Team C rallye game Tires [Klick] and they are nice for some bashing with buggys on parking lots ?

I still want one of these.....!!

Soo, my setup is ready for some testing

Now I have some used GRP wheels (S3 in front and S4 on the rear) and some wheel hubs with 2mm offset in the back.

4.680g ready to run with a 5S 5000mAh lipo... I can't wait to test this beauty

Love that radio (jealous)
That 4274 looks so little in there. Should be a fun parking lot racer!

I know what you mean... Normally it is no small motor but in this long chassis it looks realy tiny ?
