Interesting to hear.

I have tried multitude of roll center adjustments, different pivot block widths, spring, oil & piston changes & while those helped, my 417 Raceberry was just easier & more consistent which ultimately led to faster total times.

Was your Yoke comparison an original BD7 or the 2014 version?

Rheinard posted a link on his facebook page to a race report. There are a couple pics of him wrenching on his car in there. You can see the motor mount a bit. I'm sure it's just like the BD7.

I'm sticking with my 418 for a while. Too expensive to switch and, if I do, I'm going to give the Arc 2015 a real hard look. :nod:

I think I'm gonna unload my brand new half built 418 for pretty cheap. If anybody in the US is interested send me a PM.

I owned the original and drove a 2014 several times. Neither one felt particularly good to me on carpet. The 418 is a bit nervous, but it turns really well which is what I care about most in a car.

Think this is the latest vid. Notice the new suspension mount holes from under the chassis. Gotta buy all new ones...

Don't think Tamiya will be nice enough to give us an insert style split block? or is that wishful thinking?

Those sections do not make sense to anyone who does speak English as their first language!

It's a bit of bad translation

Doesn't help that there are words in the Japanese language, especially when it is technical type terms, that do not have a direct English translation.

Like "Giyadefu" - it pretty much means "gear diff assembly"! :)

You see it a lot in full size car tuning circles, as well as plenty of japlish. there are some awesome marketing statements out there. Especially ones from the 1980's!

It seems it is only really the mod guys complaining though - and MR in particular obviously! - but for the lower specs, it seems to work really well.

It's tough, easy to build, doesn't tweak easy etc etc.

I'll still buy the new one though. Will give me a good car for 21.5t and one for 13.5t :)

Maybe they'll clear old stock by releasing a 418MS - Maximum Sh!t edition. :lol:

ROFL the irony in the acronyms. but knowing them, they probably waited until the very last one was sold before announcing the 419. Now that they also developed suspension blocks unique to the car, I wonder where they will take this to.

EDWARD2003 08-20-2014 06:34 PM

Food for thought :)

The correct term is "Katakana" not japlish. Their syllabary consists of three writing systems; hiragana, kanji (Chinese characters), and katakana. Hiragana and kanji is used for Japanese language words. Whereas the katakana writing system is used for Western words.

Their alphabet is completely different to ours. We have A,B,C ect. Where Japanese have a ton of pairings such as Ka,Ki,Ku,Ke,Ko. The only similarities between the two alphabets would be Japanese letters A,I,U,E,O.

My name is Edward and is obviously it;s a Western name. So my name would be E-DO-WA-D0.

Giyadifu GI-YA-DI-FU
Amerika A-ME-RI-KA

Also, Japanese sentence follow a S.O.V structure. English is S.V.O, so that's why you get some really messed up translations. Also, Kanji has multiple interpretations, so you'll get some really odd words thrown into sentences.

Thought this would be interesting for some of you.

Onomatopoeia is simply describing something by using sounds. For example, to describe a cat we say "meow" or pig "oink." The Japanese have thousands of these sounds and use it in everyday life to describe many things. I find this is especially prominent in r/c racing.

When I started gluing my 1/12th foam tires, the store owner helped me. He kept saying "guru guru".. I was like what the hell are you saying? He showed me that once the foam is on the rim, you put the glue nozzle in between the two and "guru guru"... Guru guru??? I found out "Guru guru" is an action of moving something in a circular motion. :rolleyes:

Well, I don't "know" exactly but reading around coverage of the larger races like ETS people have been talking about these redesigned diffs that hold a bit more oil. I would think Tamiya would be correcting the fact that to really build a solid, reliable diff you must sand the backs of the gears and at least in my experience throw out the thin 0.1 shims and use individual 0.2 or 0.3 shims depending on mesh.

What do you think is wrong with the motor mount? Not challenging, I am just curious myself.

I don't think there's anything wrong, but if they changed it (and it seems they just followed the Yokomo/Samix recipe) they must think something's wrong, I imagine?

I always sanded the gears (including in Xray diffs), and I found the best diff on the market right now is probably the Schumacher. And yes, I have all the Tamiya diffs, Schumacher, Corally, Xray, Spec-R, Yokomo (don't have AE, but I guess those won't be far from the Yok ones). The Xray diffs are again a brilliant diff, light, precise, smooth, perfect material (seems to be the same as the Schumacher). Tamiya is lagging behind, but not the volume, I don't think that's the problem. Their diffs are too chunky and look just like a Spec-R diff coming off a better mold. That's it. Not worth the 50 bucks or so, really.

But for capacity, I would guess the Schumacher diff is the smallest (if you discount the Corally) and I don't see a problem with it.

If I had a recommendation about diffs that would be to go to lower tooth count so we can get the spec ratios easier instead of resorting to intergalactic pinions that obstruct access to motor mount screws. I changed my diffs to my liking (my 418 is running Xrays) for that reason, but also to take advantage of what I consider the best gear. I have on my list a test run with the Schumacher diffs in the future as well.

This would offer Tamiya the option of lowering the bulkheads too.

As for the motor mount, from the video above it seems they just went straight to a Yokomo 2013 type with the possibility they'll move on later to a BD7/14 or Samix type.

The suspension blocks are again identical to Yokomo. If the holes match, even better for me!

All that's left is to adopt an Xray type servo mount (like they have in the TRF503) and I'm happy.

But all of that is no innovation. A revolutionary move would be if they tried a proper development of their shaft drive car to bring it up to spec and push into Awesomatix territory. Looks like a very tasty chassis, but it just doesn't convince, reports are mixed and results inexistent, some crap basic problems with plastics, and gears from last century. This is where they have a choice. Leave Awesomatix to get further ahead, or dive in balls out so to speak. I mean serious stuff, hypoid gears, titanium bulkheads, the works. Especially since it seems they want almost 700$ for their car.

Yeah, exactly.

It's a little more like this when pronounced - Ge-yaa-dif-foo

Katakana and hiragana look different too. Katakana syllabary has a sharper look to its design. Hiragana has a more smooth and flowing.

タミヤ Tamiya is in katakana
ヨコモ Yokomo is in katakana

Now both in hiragana

たみや
よこも

See the difference?

My name is Edward.

エドワド in katakana
えどわど in hiragana

You will never see my name or western words spelt in hiragana. It's strange to do so. Since Tamiya and Yokomo are international brands I guess they have decided to switch to western style of writing. If you have a manual with Japanese check it out.

Ah, so is it more of a case of thats the Japanese way of saying/spelling an English term as opposed to the Japanese word for it? (ie: cause there isn't actually one?)

They get foreign words, and pronounce it in katakana, and then it becomes a new vocabulary. The term RC(radio control) becomes ra-ji-o ko-n-to-ro---ru. On top of that they usually abbreviate it with the first two characters of each term and end up with a single term (ra-ji-ko-n), which almost everyone in Japan understand its meaning.

Exactly, but this isn't the case for all words that we think are "westernized."
For example, baseball. You would think it would be BA-SU-BO-RU. Interestingly the Japanese have their own word for it, and it's called Puro Yakyuu (ぷろやきゅう). See how it's not written in katakana, because it's a Japanese derived word. Same with car, which is called Kuruma. But these words are very common and be interchanged without much confusion. :cool:

I won't hijack the tread anymore :lol:

So that 419 looks すごいですね!

d16dcoe45 08-21-2014 06:42 AM

Looks like the layshaft mount is rounded on top like the Yokes which means you lose the ability to connect the top deck to the layshaft mount with the 2.6mm screws & 0.5mm shims. Has anyone actually tried their 418 with the mount connected to the top deck? More/less rear grip?

On another note, why doesn't Tamiya do the obvious logical change and locate the pivot blocks PROPERLY using a couple holes in the chassis and 2 locating dowels per sude that actually fit tight, unlike the floating servo mount & upper bulkhead ones which more or less do nothing. So many times I have to shim one pivot block different than the other because they are being located entirely by the flat head screws going into the chassis. If the screws are a little crooked or not perfect (even new screws) those pivot blocks wind up sitting a little crooked. One side could be 3.2 degrees, the other may be 2.7!!

I love Tamiya, but I don't run this car because I think its the absolute best sedan, I run it because of the quality of parts, the different options they have, the parts sharing across platforms and frankly the fact I grew up with them--my first hobby grade RCs were Tamiyas and they got me in this awesome hobby, but it would be nice if some of their ideas were executed better especially on a $500-$600 TRF chassis in a crowded sedan market. So many cheaper options that are as good or possibly better, that you have to LOVE this company to want to run this car.

I am probably a Tamiya fan-boy and I got no problem admitting it!

niznai 08-21-2014 07:37 AM

Those crappy images look like they adopted the Yokomo style of keying the suspension blocks. I have noticed the slop in their keys too, hence the expression "tamiya slop".

Here's my way of dealing with the blocks. When I tighten them down I have a piece of square tool steel clamped across the chassis to both blocks to make sure they point towards each other (I assume that's the best way to make sure they're square; if both have the holes in the chassis skewed the wrong way, I'm screwed). Then I do up the bolts from underneath. Seems to be working fine, no difference between left and right toe.

Yeah, you may be a fanboy but if you didn't catch on, most people here are. Personally I like Tamiya cars, but I think they could do a lot better for my money.

xrayaustin 08-21-2014 06:41 PM

I'm not sure where everyone comes across as seeing the 418 as so bad. I mean let's be honest the c hubs need work and the kit chassis is way to stiff (almost backward weave imo)

But this car is very good and absolutely capable. Yeah it may take work to get good and time and effort but let's face it. At the top level you're going to wrench to find that 1 tenth anyways. It'd always like that. Coming off of being a very accomplished racer of the xray line of cars I couldn't be more happier.

all cars need help and tlc. This is not a bad car imho. Not perfect but not nearly as bad as everyone claims it to be. Not trying to be mean but the ones saying how bad it is probably need more wrench time and they would realize working on ur car goes along way.

Sorry about the rant...

on to the topic. I hope the car is good. Kind of shocking to not see a newer version but can't wait for the release. It all lools like good changes. :)

frozenpod 08-21-2014 07:01 PM

+1.

JimmyMac 08-21-2014 07:08 PM

The "bad" talk of the car didn't stop me from buying it. I actually like it a lot (except chubs). I just picked up the Samix Aluminum chassis for it. Gonna give it a go in practice this weekend on carpet. It'll be my main car this winter for carpet season starting next month.

Commenting on the new style suspension mounts, I think the "L" style separate mounts help prevent chassis tweak. What I noticed when installing the aluminum chassis on my 418 was that when you tighten down the separate mounts, the chassis will start to tweak. Not left to right but front to back. Loosen the separate mounts and it goes away. Not only that but with an "L" shaped mount, you can narrow the chassis a hair more in those areas.

These are just my observations so far.

syndr0me 08-21-2014 07:08 PM

On carpet, I think the 418 is the second best car I've driven, second only to the Awesomatix. It feels quite a bit better than the T4'14 and BD7.

The gear diff has needed some attention for a while. I'm glad to see they're taking another look at it.

I sincerely hope they're not just trying to copy the BD7 though, because everybody I've seen drive that car goes slower with it. Ronald is amazing, but that car has never looked great to me in the hands of mere mortals.

The opposite is true on our carpet track

Though I have also seen many other brands go well occasionally, even the 418

Which cars are working the best at TQ?

Burlap 08-21-2014 07:28 PM

I'm surprised that Tamiya are bringing out the 419, considering how long the 415 and 417 lasted in the market.

There were huge bulkhead changes between the original 415 and 415 MS/MSX and Tamiya stuck with calling it the 415. Will be interesting to see clearer photos of the 419 to see what the changes are

EDWARD2003 08-21-2014 07:42 PM

The main culprit who started this whole 418 is "bad talk" started by none other than Mr. Maximum Sh!T. After his unsavory comments about the chassis and his mediocre results psyched out some potential buyers and therefore opted out from purchasing the chassis.

Also, I would say this is the year of the "Volker." Very well Marc has passed his prime and it's hard for him to accept..

frozenpod 08-21-2014 08:20 PM

To say the person who regularly finished ahead of everyone except one other racer 'is passed it' is a very big call.

Agreed Marc should have kept his mouth shut but venting frustration is to be human.

In the later rounds with a few updated parts they were by the end of the events toe to toe with RV. Shame they didn't run as well during qualifying as they may have won a few more rounds.

cplus 08-21-2014 09:33 PM

Someone once told me "MR could put a TT02" in the amain.

And it is probably true. The guy is very, very talented.

The difference for Volker this year is timing/luck/consistency.

He has dominated ETS for a while now and was pretty close to WC in 2012 don't forget. He hasn't just all of a sudden appeared on the scene.

The difference isn't necessarily the fact that volkler is any better. I was told by one of the best American factory mod drivers at a race recently that at the top level (ETS, worlds, etc) that all of the guys Iin the A main have the same amount of talent. He said the only thing that matters at that level is your mind state and mentality. And that is absolutely 100% true. I you don't have the mind state of going into a race feeling like your going to win and don't have the confidence In your car (MR calling his car maximum shit) then at that level you're going in already behind the cue ball. All it will take is him to win one big race over Volker and the whole team will rise up.

do not count any of the Tamiya drivers out at world's this year

cplus 08-21-2014 10:09 PM

Hell no.

And you've seen a distinct shift in attitude since there has been a mechanic (Kiyo no less) and set up guru groskamp at the meets.

That will help a little....!
