Tamiya's Latest: Countach 1/10!

[DeeMiller]

but it is...

Thank you!

[mosiac]

The average CNC machine only runs a PC of 'average home grade' specs. Alot of the G code files we were using never went over 25k in size. They aren't supercomputers.

[terry.sc]

If you actually sit down and think about it, which of these is easier to do. Enlarge a 3D model, then just let the computer create a new set of toolpaths,

Yup!

Like "flipping a switch"...

Now we're getting somewhere!

Nope, sorry Dennis. You can 'agree' all you want but it isn't the same, in the same way that enlarging a jpeg by scaling it up isn't the same as using proper interpolation software. Enlarging the 3D model and getting the computer to recalculate the toolpaths isn't the same as just telling it to make it bigger, you have to create a complete new file to send to the miller.

If you take the 204mm wheelbase of the TTG and multiply it by 12/10 or 6/5, you'll come up with 245mm wheelbase for the 1/10 version.

Maybe Tamiya has found a way to shorten it even further or maybe the shell is bigger than usual if they stick to the 251mm of the SWB TT01 (which I doubt).

I've measured the width of the shell which is 166mm and did the same: width will be 199mm (if they keep the 1/12 proportions to the 1/10 one, which is still my point).

All you are doing is enlarging the TTG while keeping the same proportions, which just doesn't fit a TT-01. You can speculate all you want but Tamiya isn't going to build a special extra short wheelbase, extra wide TT-01E just to keep you happy with the proportions. It will be on the 251mm wheelbase TT-01E, and most likely to be 190mm wide. BTW the Countach is more accurate at 200mm wide on the 251mm wheelbase than it is on the TTG chassis, the TTG chassis was designed around the Porsche so the Countach has been shortened to fit.

PS Do NOT call a CNC MILLER a dumb machine!!!

It is dumb, it's as intelligent as those 'follow the line' toy robots you can buy and they work in a similar way, give it a line and it will follow it - except the toys stop when you put your hand in front of it

Some Tamiya provided info on the LP500S TT-01 Type-E kit:-

-New polycarbonate body captures the beautiful form of the Countach.

-Mirror, rear wing, and metal plated light case are separately-molded parts.

-Head lights are in the down position (Can not pop up)

-Short wheel base (251mm), Rear wide tread (Uses long wheel axle).

-Countach LP500S (TT-01E) wheels. Front offset [+2] Rear offset [+4].

-Racing Slicks (Item 50419) provide excellent traction for high speed racing.

-LED Lights: Fog lights (5mm white) x 2, Taillights (5mm Red) x 2 are included.

-Both front & rear light cases have two 5mm and four 3mm LED Light installation points.

"-Head lights are in the down position (Can not pop up)"

Mr Dremel begs to differ.

I thought the US spec bumpers were ugly enough

then i saw this

THANK YOU!

I guess I have to find someone who's going to CNC some custom OZ wheels for me then...(looking at the 50547 wide racing slicks for the rear).

humm... and so my speculation was correct... even though 50419 pops up as racing radials as per tamiya usa search result.

Rear long axle + 4mm offset should be around 6mm offset.. quite similar to HPI's vintage rears. Nice, fat *******. HPI's countach looks so skinny now...

[gt6++]

Anyone else disappointed that this will be on the TT-01E???

These 251mm wheelbase bodies are getting on my nerves!!

[terry.sc]

1) language

2) The offset will just move the wheels out, it will still be on standard 26mm wide tyres.

The 6mm offset does mean that the HPI vintage wheels and tyres will fit under no problem.

[Blacque Jacque]

I fail to see how you can accuse the HPI Countach of being skinny, it's 200mm wide at the front & 210 at the rear!!

Technically the wheelbase is longer at 255mm, but that's less than a 2% difference.

As for the chassis choice, I would imagine the TT01 in it's various guises is Tamiya's biggest selling tourer chassis.

[TA-Mark]

Ewww... 251mm on a TT01E chassis. Guess I'll be buying the HPI one and fitting it to the same chassis I run my HPI GT-40 Body on, a modified TA03 RWD only.

As for the chassis choice, I would imagine the TT01 in it's various guises is Tamiya's biggest selling tourer chassis.

You get that when they sell all the nice bodies on an entry level chassis. I'd rather just buy the body set and fit it to a real chassis, but they fixed that by changing the wheelbase...

TY Mr Tamiya

Hmm, now that I think of it...

Does that mean the wheels are actual Countach wheels???

Grtz Dee.

I call the hpi countach as skinny, not looking at the actual width, but looking at the rear wheel flares. at 200/210mm width, it's simply mean that it's made to fit 200mm chassis.

it a visual impact thing. HPI did the body a tad bland... I have the body right in front of me.

All these bodies and still not a Vector...

[stulec52]

Am I missing something?

Seems to me the Coutach while certainly iconic, was an ugly ugly ugly car.

Give me a Porsche over one of these any day, real or model.

Just my opinion of course.

[Origineelreclamebord]

I don't really like Lambo's, so neither the Countach (it looks better as an RC than 1:1 though), but this should be interesting.

A shame they will release it on a TT01, why not use the body on the TB03? It will be interesting though to see how they are going to widen the car so far so that the wheel wells are nicely filled up. Plus, it will be another 1/12 --> 1/10 release. And even better, it's not a space age japanese monster like all those Nissan's they've been releasing over the past few years

[B.M.T.]

The HPI Countach looks skinny, becasue it's too long for it's width.

[irenL]

correct-o....... which is why tamiya shortens it another 5mm on the wheelbase.

the other thing i don't like about HPI's is that they got the lexan too thin at several parts of the body, that it cracks easily when trimming.

WOW.... 3 pages already...

anyways, if it were to go on the TB03, whom reversible rear arms doesn't change wheelbase from 256mm either way, then they might as well commission HPI to do the bodies.

I'm currently waiting for my 200mm NSX body (non-GT style) to arrive... should make a good pair...

And I think I'll go for another F40 as well.....

[Blacque Jacque]

The HPI Countach looks skinny, becasue it's too long for it's width.

Actually, it's not.

It's too wide for it's length:

Wheelbase : 2450 mm (96.5 in)

Front track : 1492 mm (58.7 in)

Rear track : 1606 mm (63.2 in)

So for a true 1/10th model it should ride on a 245mm wheelbase & be just 149mm / 160mm wide front & rear respectively.

Tweaking it for the 251mm TT01E gives (2.44% larger):

Wheelbase : 251 mm

Front track : 152.6 mm

Rear track : 163.9 mm

Those specs are for the LP400S, the 25th anniversary / QV has 50mm longer wheelbase but identical f/r track.

Using the QV dimensions makes it even narrower as the wheelbase is just 0.4% off in 1/10th scale.

The HPI shell is 255mm wheelbase & 200mm / 210mm f/r track which is way off in scale terms.

All of which brings us back to Terry's point earlier about setting the wheelbase, then stretching & squashing it in various dimensions to make it "look right".

These are NOT true scale models, they are very good approximations.

The original 934 / 935's are probably the only truly accurate rc models Tamiya produced as they were derived from static kits rather than dropped onto existing chassis'.

correct-o....... which is why tamiya shortens it another 5mm on the wheelbase.

the other thing i don't like about HPI's is that they got it too thin at several parts of the body, that it cracks easily when trimming.

You'll find that a potential problem on any lexan shell, the sides are stretched most when vac forming & areas such as the return around wheel arches etc will be particularly thin. The HPI shell I have shows no thin or weak areas at all, the HPI Pantera was the same.

On the other hand I have an ABC Stratos that is very flimsy in a couple of areas, it's just the nature of vac formed bodies.

You can use thicker material to produce a stronger shell, but that will generally sacrifice detail.

[B.M.T.]

Track isn't over all width, in it's true sense. Track is measured from the center of tread to center of tread. So, in the 1/10th equation, you could another 25mm or more to the width. That only gives you outer sidewall to outer sidewall. Add x amount to come out to the edge of the body work.

In over all width, a Countach is close to 2 meters wide.

if memory serves me right, the countach replica made out of the chopped and add pontiac fiero I saw some time ago was 2 meters wide..

running on 15" donuts.

looks nice.. but the wheels turns me off... it'll look better running donuts IMHO, especially in the rear. Side naca ducts could have been made deeper...

O well, at least i can confirm that I'll be ordering the body set.

any part number?

[DeeMiller]

Thx for posting the pic!

From that angle, it looks too wide for it's lenght...(or too short for it's width) which is remarkable considering the 251 mm wheelbase.

Hmm, must be the picture then.

One thing I really don't like are the wheels but I was already afraid of that.

Hope to see more pics.

[B.M.T.]

I don't know. It looks to be in proportion to this

and

I think I have worked it out.

It's the new wheel arch lines, to accommodate severely over diameter wheels make it look short, becasue the apertures look closer together, becasue they are much bigger than they should be.

[Blacque Jacque]

Scale wheels just don't seem to exist, the only thing close are Mini wheels & the tyres to fit them are way under size.

It seems you can have anything as long as it's a rubber band on 20" scale rims

There's just nothing out there with a tall sidewall, HPI's vintage tyres are a reasonable effort, but they need special rims which severely curtails their appeal.

And whether you love or hate them, the telephone dial wheels are as much a part of what defines the Countach as the rear wing, air intakes etc.

From what I've seen so far Tamiya's effort is no worse than HPI's, so yeah, I'd buy one
