A buddy of mine is getting his this week. I'm excited to see how it is compared to my DTM2. The shorter/stiffer chassis has me nervous, as my driving style may not appreciate that. I would love to get a DTM3 tower and try that though, for some extra droop.

I'd not worry about chassis stiffness. With the shorter chassis, new shock package and battery mount, it will generate a lot of grip. My CAL3 was super planted with the kit set-up from the get go, and I'd be surprised if they did not manage as well with the dirt car. I sent arn0 a few lines to complement the built report, and they should be online soon.

The DTM3 is a nice piece of a kit.
The Cal3 therefore is a shame. The Ca2 was a way better deal for the money.
Yokomo did nothing good for the high grip community. Did you see, that not a single piece of alloy parts ate included, neither
are the any graphit goodies in it.
Even the rear arms are S3, so the car is very narrow in the back. Way to much grip, so they decided to take the grip away,
look at the strange setup fot the rear suspension.
My S4 arms car is 4mm! wider in the rear for onpower steering, which lacks the Yz2 platform anyway.

And for all who wants to use the -3mm rearshock plate, you do not need the truck shock bodies.
You can still use your original shock bodies, with only 3mm spacer inside.

And for the steering rack. If you have the Worlds alloy steering or the Dtm2 alloy steering, its the same as the Truck plastic one.

Sorry but Yokomo has not done sny favour for them with the new kit.
Expensive and no real innovation or expensive parts, like the Worlds Edition, in it.

yeah that was a typo, corrected it.

The new parts, are they different material wise than the plain plastic ones? I was thinking they are harder than the plain plastic but not quite as stiff as the graphite ones? maybe better durability that way?

As for the alloy parts not being included, one thing posted up on facebook was I guess they did this due to some complaints on breakage issues, so this may give more flex / less breakage. I don't recall much breakage issues personally on my YZ2 lineup of cars, but maybe others were pushing stuff harder than I tend to do.

I am curious on how the shorter a-arms will perform, will be interesting to see. Do you plan to do any back and forth testing, if even possible, of long S4 arms versus the new shorter ones?

Do you run into any issues with the shock body being longer than the truck fronts?

To confirm, you are saying the center link portion from this is the same as the the plastic center link (Z2-200-3) for the CAL3/DTM3?

Did you drive the CAL3? Obviously not.
FYI the inboard steering set-up is completely different. I don't think you can swap those items.

When it gets here I have a YZ2T I can do some comparison on at least for the steering link part since that is in question. In general how the vehicles performs is going to be a big factor relative to perceived value based on what is or isn't in the kit. Folks love bling,and when you are at the top of the price point, lots of them think more bling the better, regardless of how it actually affects performance.

No, I did not mean comparing the new Ca3 steering and Worlds one,
I mean the Plastic +2mm is the same as the alloy Worlds, alloy Dtm2 one.

No problems running the longer shock bodies on the shorter stays.
You still have 1-2mm uptravel, when chassis on the ground.

When all plastic works better, why I am around 1sec. faster with graphite plastic and almost everything in aluminium.
My goal is getting a setup that the car reacts always the same on every part of the track.
All plastic makes the car a little easier to drive, but very unpredictable, and I cant stand this.

I am not a real racer, but I could match up the speed of Bruno Coelho at our home track.
He and all the other Xray racers had a hard time at our fast and bumpy Astro track.

got a setup you can share? we run on bumpy astro here.

Personally, I prefer aluminmum for the inner ball stud mounts but that may just be my hang up.

Looks likemy CAL3 will be here today.

mes 08-14-2019 09:34 AM

Yay, the interweb swallowed my reply once more...
Short version:
- aluminium and graphite plastics can be valuable set-up options, but can make your car slower on certain tracks (in my experience this was the case on smooth Astro and indoor carpet)
- the CAL2 was insanely well equipped, which makes seem the CAL3 a worse package than it actually is (coated shocks, machined internals, adjustability, steel bulkhead...)
- world-class drivers not outperforming local heros speaks volumes of the difficulty of the track in question
- my P2K is finished

What tires are you using?
This is the most important factor for the setup.
At our track Schuey Cactus are the best, long lasting, do not tend to grip roll, best handling, wear and grip.
Schuey Mini Pin best grip but difficult to drive
Schuey Dart good grip, but after 3-5 batts done.
Schuey Mini Spike less side grip, also short life span
JC Swaggers, Lockness the best rain tire on our astro

my set up is for Cactus and Mini Darts
https://cimg0.ibsrv.net/gimg/www.rct...26e079738.jpeg

you can also use RP orange for more rear grip.
Body is the best one JC F2, front wing,and for tighter tracks use the steel bulkhead.
For open fast tracks, longer bends use the alloy bulkhead with 11gr. weight.

DirkW 08-15-2019 02:06 AM

So, you are running the DTM, not the CAL on there?

A lot of the guys at my track cut the rib off the front of the Schumacher cut staggers. Are you guys doing the same?

Cain 08-15-2019 09:22 AM

here for tires it can bounce back and forth between cactus and mini darts in yellow compound for our turf. I prefer the mini darts personally as they last awhile and seem a bit more consistent since we run into the night when it starts to cool off, offer better grip.

Lockness can work here too, but our astro has gotten really "packed' lately for lack of a better term. so at times it feels like the pins are not driving into the turf like they were before. I'd be curious if nessi's would be better.


CAL3 is here, and of course injured my pointer finger before I could get into working on it go figure lol. so its been doing a good job of the box starting at me. Lots of building this weekend going on, CAL3, LC12B1, CAL2s for comparsion, YZ2T and YZ4SF setup changes, and then some 1/8 scale JQ stuff to round it out. lol

smrcboy 08-15-2019 10:21 AM

yes you are right, cactus are only good on sunny days.
for any other condition mini darts are the better option.
are there any good astro tires from proline, like the prism?
wevuse them on trucks, and these are way the best ones.

dont know how to name this car. ca dtm? its my yz2 for astro.
we are running the -3mm shock stands for the complete season, as we make these for ourselves.

Cain 08-15-2019 11:42 AM

its the DTM Worlds edition with some upgrades if i recall correctly. I proably would have saved the chassis and got another regular to run on it lol.

for guys runing proline the pyramids seem to be popular.

mes 08-15-2019 10:29 PM

On our track, Darts are the fastest (for a few batteries) and you can get away with Cactus. Pyramids will last long but are quite slow compared to the Schumacher tires. My personal favorite are the Nessis, which are very close to the Darts but last much longer. I will have to give the Twin pins a try, but at the moment I don't think it's going to get better than the Nessis. Great tire all in all!
