WIP: Tamiya 1/20 Tyrrell Yamaha 023

Tyrrell Yamaha 023
Mika Salo
Brazialian GP – Interlagos – 1995


(Image from Formula Perfect Manual Series, Volume 6)

My next build is the Tamiya 1/20 scale Tyrrell Yamaha 023 driven by Mika Salo in the 1995 season opener at Interlagos. Mika finished 7th in the race, the podium filled by Michael Schumacher, David Coulthard and Gerhard Berger respectively.



The most obvious difference between the car on the box and the one in the photograph is the colour. I decided to build the all blue version primarily because it will involve less masking but also because it looks better and I haven't yet seen one built. I choose to build Mika's ride rather than Ukyo's ride simply because Ukyo didn't finish the race. Also, I wanted to even things out as most of these models have been built as Ukyo's version. Also, Mika scored all of Tyrrell's championship points that season.

The less obvious difference is that half way through the season Tyrrell ditched their innovative hydraulic suspension system. Therefore, I am going to attempt to recreate their original suspension system using the reference pictures in the wonderful Formula Perfect Manual Series.

Anyway, on with the build...

The first part the I am going to focus on the the front wing and nose cone assembly. I separated the nose cone from the monocoque (as it is one piece in this kit ).



It also meant that the underside piece needed to be separated too. No big deal, I just wish the kit had been designed to have a removable nose cone. I also drilled out the little holes on the front wing side fences, as I am going to hinge the front wing and place a pin through the hole.



You can see in the final image, I had drilled holes ready for the metal bolt heads.



As you can tell, I plan for this build to be quite an adventure

Kind regards,
Bill

Cool,
nice start here Bill!

Good start Bill.It will be nice to see the all blue version built up.I must admit I have only ever seen the blue/white version before.It will be a lot easier to mask out the all blue one for sure.When you say this will be quite an adventure,will you be going to town on detailing the engine etc or just keeping it simple?

I will be going to town on the detail on this model, especially in the engine area. I plan to use lots of the RB motion hardware I got recently (replacing nuts and bolts) and scratch building anything that is omitted.

The only area that I plan to leave alone is the top of the front suspension under the front monocoque cover... the reference photos all show the geometery covered up so I really am not too sure what it looks like. In any case, I don't think my scratch building skills are up to getting it perfect and any issues there will be magnified with front ride height and what not.

Kind regards,
Bill

Nice one Bill, I'm looking forward to seeing this build come together.
It's also on my to do pile so hopefully I'll learn a thing or two from your experience!

Tell me, what do you think of the Formula Perfect manual?

I have four Formula Pefect Manual's for all the 1/20th scale cars (Jordan, Bennetton, Lotus, Tyrrell). The whole series is excellent even if, like me, your Japanese is not what it should be . The Tyrrell book is no exception and is excellent too and is the primary reason I am building this car now.

I could be critical about the photographs as they are not always as detailed as one would like. Also, it can be quite difficult to work out which race an image is from. However, you won't find reference pictures as good as these anywhere else for this car (unless there is an issue of F1 Modeling covering this car that I don't know about).

Price wise, the books are a little on the expensive side but at least they are in demand and so their second hand value is high should you wish to sell on after the build. I got mine from Mac at Mac Modeling and I think he has some more.

Bottom line, if you are building this model and plan to do any detailling, the book is essential. Even if you are not, the under the cover photographs will help you learn how F1 cars of that era are plumbed, wired and the types of CF used too.

Hope that helps,
Bill

Great start, I'm looking forward to watch and learn as this one unfolds. I like the cars of this era as they look fast sitting still but aren't super-complex.

Thanks for sharing.

I am building this version. Brazil or Argentine GP or Presentation car. They are similar but different.

Here I have some extra pictures. take in account the air intake entrance above driver´s helmet. It is different from tamiya version. it needs some scratch job here.

There some ways to that. At night, I can put photos of the way I have choosen to do it. See that there are some differences to do that part of the car where driver touchs the back of his head on car. I do not know how to say it in English. I hope I can be clear. It is different according to presentation and others GPs.

here all that I have.

Cool. Is it on here? If it is I must have missed it. Thanks very much for sharing you reference photos. They really do help to understand the differences --- not just between the white/blue car and the all blue car, but also the differences between the three iterations of the blue car (Presentation/Brazil/Argentina).

Yes you are quite right, there are a number of changes/decisions that need to be made:

1) In profile, the sides of the head-rest need building out so that it is flush with the downward leading edge.
2) When looking straight over the driver's head into the air intake, the bottom of the top of the loop has a horizontal surface (clear to see on the Mika Salo/Brazil photo in my first post) but strangely not on the presentation car.
3) Colour/material. Some photos show the head rest to be dark blue, others white and blue. Some photos appear to be a smooth leather type material, while others show a fluffy suede like material.

Thanks very much for your help,
Bill

[badi]

well,

this is the way I did. I just sand the air intake until it only faces the head rest.....this was the word...thank you!!! and I glued it all together.

You can. My car is going to be a curbside, cause I have the other version with the cowl opened.


I think my links are working now...

[billypee]

Yeah, we call it a head rest here in the UK, although strictly speaking rest is a contraction of restraint rather than somewhere to rest your head although for most people the distinction is subtle.

That is a very nice start you have made to your Tyrrell 023. I notice that you have closed the cooling ducts on the rear cowling side pods. Do you know for sure that was how they were? I have been unable to determine how to model them for the Brazilian GP.

Kind regards,
Bill

Hi Badi,

I have been trying to answer my own question about the cooling ducts on the rear cowling. Salos car in two of the reference photos you provided has the cooling ducts open. However, it could be Brazil or Argentina in those shots, I just don't know. The title of the images says ersteLackierung which translates from German to English as first lacquer finish (well according to Systran on my Mac it does). And, well, to be honest, that makes no sense. Can anyone here who speaks better German than I confirm if it also means something like Salo's first GP finish?

The images appear to be from the same race, and it appears to be wet. However, it says that Brazil was a dry race. However, the horizontal bottom surface to the top of the hoop appears to be evident on these photos, indicating that they are Brazil, because according to F1 Facts photos, that part is arched for the Argentine GP. Compare these images:





Bottom line: I guess that the cowling will be open for both Brazil and Argentina. Presentation cars tend to have no cooling requirements so they cover up all the holes to make it look pretty. Unless I find evidence to the contrary, I'm going to model this car with the cooling ducts.

Kind regards,
Bill

[Shunter]

Excellent choice of version. I really liked the all blue version as well. Look forward to seeing this one come along. Nice start with the nose and front wing.

[badi]

You are right !!!

both ducts were opened during these GPs.

In Brazilian GP there was no small deflectors in front of car. During Argentine GP, I do not know.

Have a look in first 2 pictures I post before. They are from Brazilian GP. It rained during this part of this GP.

here I have pictures of other version of this car built in 2004.
