Front spool
Rear gear diff 1000k
45wt oil all 4 dampers
White front springs
Blue rear springs
Alum c hubs
Stiff swaybar front and rear
2.25mm lower deck
2.5 mm upper deck

Issues: waaaay too twitchy. I have a very fast servo, can that be the issue? Should I go back to the stock decks? The rear is too eager to kick out. I feel that once the twitchiness is resolved, this too will be reduced/removed. The twitchiness is at initial turn in Abd my correction does nothing to assist in reducing it.

A local who also raced the 417 said ot was never good on carpet, tge chassis flexed too much. I explained that I now have the stiffer decks and he said he may bring his to do carpet also.

The surface is traction compound soaked carpet. It's very high bite.
Try less toe out in front.

Also what shock positions are you running? Getting them more inside calms the car down quite a bit

what is the reccomendation for swaybars? Remove them also?
All 4 hubs? I'd shave a few grams by doing so...

Go back to the kit roll bars, they work on pretty much all tracks/surface's. Most racers dont run any Aluminium parts (uprights) on the cars as they can bend quite easilly, but the bend can be hard to find. Causes a lot of tweak issues and car missbehaviour. Your shock oil is also very hard, try going softer and as others said lay the shocks over if you are still running them upright, and less rear toe in.

Did a spring clean of my 417x on the weekend and replaced a few bits that were wearing. Amongst these were the front spool cups. I'm using the Tamiya DCJ's, but noticed that they seem to bind a little on the new Tamiya spool cups.

Is this something I should worry about? Would replacing them with something like the Spec-R spring steel ones be a good idea? Is there another approach?

Roche makes some made of spring steel. I cracked 2 of the tamiya ones, these show no signs of wear with 2x as much use.

Surprisingly the arena ones are good too, half the price as roche and come with two sets of slots! #winning

Most of the time the team guys use cst rating for oil, so 450cst is not 45et etc. Im not sure what brand oil you are using, but associated shows the cst rating on their bottles. Personally I use Muchmore oil which is all rated in cst

I didn't know that. I am running muchmore 450 and thought 450 was 45 weight.

First of all there is a reason why no one of the top drivers use aluminium c-hubs! ;-)

They bend fast and you canīt notice that easily! And also they stiffen up the suspension...

You can try the setup which iīve posted, it works great for me!

You can try the kit rollbars, so medium in front and soft in the rear, but also medium all around!

But 3,5 deegres toe in is to much for 17,5T stock racing, even the pros in modified just run 3,0 deegres toe in!

450 Much More Oil should be just fine, also the springs and the camber settings! But reduce the front toe out!

And the other things you can copy out of my setup sheet! ;-)

But never measure the camber with one of that million dollar setup stations, if you measure it on the wheel with a camber gauge, the wheels have exactly 2° or 1,5°... That was the reason why my corally felt horrible back in the days!!!

But your servo isnīt the reason, i run a sanwa sdx-801 and tested the sanwa srg low profile servo last weekend 0,05sec to 40°!!! Feels just fine with a little bit negative expo, even in ssr mode!

Many of the racers are running tc6.1s (all but 2, me and one other driving an X-ray) are all running 3.5. They have terrible tire wear, and are much faster in the corners (which this track consists of a 25 or so straight, medium sweep, followed by 2 u turns, a very slow c-hub breaking chicane and 2 more u turns. It's a medium sized track with very little straights. The right line and you can run a 3.5 fdr.

I have replaced all the hubs back to plastic, sways back to stock and I'm back to 3* toe. I may also increase the diff side front roll center from 4mm to 5 and see where that puts me.

Does this kit would fit a TRF417 kit?

Yes it will fit.

But be sure that tis items are not made of real carbon fiber. it is something different, with carbon pattern printed on it.

Also only the lower deck is compared to the stock 417 one about 20 gramms heavier.

I orderd the lower deck, and the thickness of it was left to right NOT equal.
One side was 2,1mm and the other 2,32 mm thick.

I want to return it to rcmarket, and buy the original Tamiya, but they wrote me back that it is not possible, bla bla bla....

I defenetly never buy CSO parts.

The only thin wich is good in my opinion is of course the price, and the qualtiy of the CNC shapes and holes..

Greetings Rainer

got mine (417x) on thursday, built it the same day, raced it yesterday on carpet, 13.5 blinky with 39t pinion, 113 spur, using sorex 24's, nosram additive and a protoform speed6.

Love how this thing handles, never span out once, its so forgiving and predictable. Loads of people commented on how it just seemed planted, never stepping out of line.
