wtcc's Group C studio: Carbon parts anyone?

[wtcc5 5758]

This thread comes with a bit of delay. When the C11 was announced about two years ago, I ordered two. One went into the NiB stock and one was build in February last year. It was also then, when I checked my favorite R/C shop and found a new Nissan R91CP body set plus all body parts for it (except cockpit and sticker set). This went into the box, too.

Unfortunately I didn't made any build photos of the C11, because of being selfish and wanting to enjoy the build  Of course this car got some Hop-Ups. First the result of the C11 build:

 

Why the gold braces you might think. I wanted to make it golden all around (the body too), but then lost all motivation as I saw how the wing has to be masked. At that time I could buy a factory painted wing in silver, so the body became silver too. As Tamiya cheaped out of proper body parts, I bought the body parts for the Mercedes C-Class DTM body and used the mirror and wiper from it to complete the C11.

Another thing, that bothered me, was the position of the rear wing. The real car has it sitting higher and a bit closer to the body. I did some drawings and printed three versions until I was satisfied.

 

The chassis received 90s electronics and a fitting black and gold Sport Tuned motor. The yellow damper was replaced by the short Hi-Cap variant. And of course ball bearings for the front tires... come on Tamiya 

 

Now, with the Porsche 956 being so late (Germany seems to be the last country to get the shipment...), I wanted to build another Group C car. So the Nissan R91 will be next here.

What mirrors are they? Ive tried to make some myself from the tamiya subaru brz ones and cutting the stalk off - they are ok as an approximation but yours look better

[svenb 4240]

Don't think the UK has had it's consignment yet either!

Very bling with the gold 👍🏻

I can help you out with the sticker set for the RCP. The only minor flaw is that they come with a body and wing attached.

You can have it if you want it and cover the postage. It looks like it would be going to a noble cause.

Hi! These are Tamiya h-parts 9005434:

I can understand the selfishness of wanting to dig into that build, Kevin. I'd LOVE to have one but.........

Like the gold braces. In fact I like the whole car! These have come so far from the flat fiberglass chassis's of the 80's and 90's. I'm interested in seeing it run. Also looking forward to the Nissan R91... one of my favorites.

Very clean build!, is 787B body fittable in this chassis?

[wtcc5 5758]

@-maydeN: Thanks Yes, it is. 

 

I ordered another C11  Prices went down to 109€ including shipping in Germany  The prices for spares, foam tires and body became so high in the last months, it is much cheaper to just buy the whole kit in a sale...

[wtcc5 5758]

In the meantime @Fuijos body arrived:

 this one is a beauty! No scratch, with body parts and very well build. Saying thank you isn't enough. This generous gesture will not be forgotten!

 

I went on to the CAD-software and draw the rear wing mount and the front body post mount, taking measurements from the original R91 parts sprue. Then the printer took over:

 

The result:

 

In anticipation of the delivery of the body, I build another C11 chassis during the week. On it I installed the new parts.

The front body mount brace:

 

... and the rear wing stay:

 

I wondered why the "GoodYear" sponsor decals were missing. Fuijo told me these were not part of the rere decal sheet. You must wonder why some companies refuse to have free advertisement? No problem for me fortunately  I have a huge sticker "collection" and found six fitting ones for wing and body:

 

While at it, I put on the tire stickers and painted the C11 wheels with a chrome pen to get closer in look to the original-hard-to-get-R91 wheels. This all came together to this:

What a view 

 

[Fuijo 938]

Very nice job on the printed parts and wheels. It's looking good!

[wtcc5 5758]

Practicing my CAD skills on a diffusor design for these chassis. I try to combine realistic look with function, although the pod layout is not helping. It is also more difficult than hoped.

Work steps:

 

Comparing it to a design "juanmedinar20" uploaded on "printables.com":

 

Now, I need to make a test print and hope for the best 

[wtcc5 5758]

I will try some more things for these chassis. Somehow, I thought about a proper bumper for the C11. The classic honeycomb design with a branding:

Easy to print and nice to look at.

 

With so much space in front of the chassis... why not make it an aero-bumper? I added two front diffusors and closed all open surfaces at the bottom:

Now, this is a more challenging print...

Absolutely stunning body! 😍❤️❤️

"WHY wouldn't Goodyear want free advertising"? Brings up a short, sad story, putting down my country's selfish, litigious nature...

In the past, Companies welcomed when scale models used their logos and liveries. As you said, it was free advertising. 

For decades, Walt Disney charged Royalties on any companies using their branding on other products, related or not. This didn't really affect any of us at the time....

But in my other hobby, Model Railroading, in the mid 1990's, the Union Pacific Railroad decided they didn't like that. THEY called it infringement and "unlawful competition"...... you know, because our 1/87th scale trains hauling imaginary goods were stealing from the real Railroad! Anyway, after 5 years of a messy fight, the UPRR won a portion of the suit, for its images only. So in the hobby, every UP branded model train became slightly more expensive than any other. 

Then other Railroads decided they wanted that too... raising the cost of the whole hobby! 🤬

Then many other companies joined in. By the early 2000's, toy and hobby companies had to pay Royalties to use corporate branding on their toys! So if you wondered why all Re-Re sticker sheets are different now, with fictitious branding? That's why.

… too much greed everywhere…

I could print the diffusor and it became very nice:

 

Installation comes next.

[wtcc5 5758]

The installation went nearly fine… 

I hit all the difficult marks, but missed the easy one  

Which results in the kit spur not fitting. As I wanted to have the diffusor on the car, I switched to a Modul 04 93t spur.

Enjoy:

I decided to make a redesign that is more scale for the R91 and make variants for the 104t/70t kit spur as well as the 93t.

[wtcc5 5758]

Spent another 5 hours with CAD to make the Mercedes C11 diffusor:

The wing stay is now mounted on the diffusor, because the original is much too deep and interfered with the center part of the diffusor. As I want a balance of scale look and performance, this was (in my opinion) a necessary step  

[wtcc5 5758]

C11 diffusor printed and installed:

[ThunderDragonCy 8380]

Love the way the diffusor shape integrates into the width of the drive pod. Excellent modelling work Sir

[wtcc5 5758]

Porsche 956 time!

Body first this time with the C11 chassis used temporarily as body stand.

Looks great with the Speedline/C11 wheels!

I can’t wait for someone to come out with some livery decal sets like the 1983 Kremer Kenwood, Joest Racing Marlboro or the RLR Canon 956’s. 

[wtcc5 5758]

I am slowly coming forward with this body. It is easy to underestimate its complexity. What you see next, took eight hours… Well it is worth the struggle no doubt 

As you see, not finished yet.

@RennsportEd: I think of them the same way. The C11 wheels look fantastic on this body. I am normally not a fan of black wheels, but here they look racy and realistic. Unfortunately they will leave for dished wheels front and rear.

I don't know what it is about official tamiya photos of their models these days but they never seem to look very good, whether it's because of the angle or lighting or ride height or something else I don't know, but when people on here show their own photos of the same cars they look so much better, this one included. It looks great. 

Good work on the 3D modelling of the diffusers and other parts too. Do you make any of your work available to other to print themselves?

[wtcc5 5758]

@rich_f: Ah, yes! I forgot  

 

The diffusors are ready for download here:

Enjoy!

I think the C11 at least is a bit high, wheel wells a bit too large. My C11 sits much lower because I trimmed it lower-including the front splitter.
