wtcc's Group C studio: Carbon parts anyone?

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.

Looks good!

I put two more hours into this body.

I discovered that for this livery the wing plates have to be blue on the outside too. So another paint session was needed:

 

Then I could install the wing and add the sticker:

So this is it. Not difficult to build, but it takes a lot of time.

Some more pics with the body on the C11 chassis:

The taillights add so much realism to it

What's next Kevin? Any chance you might source a 787b body?

[Carmine A 2565]

Kevin.... I only wish there was a LOVE button!!

[wtcc5 5773]

Thanks guys 

@Pylon80: Would love to have a Mazda and a Jaguar, but chances are low to get them for an ok price. At the moment, I have other things in the pipeline for these chassis and the 956 is not finished. I hope these things will entertain you, too

Great new thread Kevin. Outstanding results for sure. Where did you source the Rothmanns stickers?

 

[wtcc5 5773]

Thanks! MCI who else 

I made so much more for these cars, but found no time to post it, yet…

 

[ruebiracer 1181]

Thank you Kevin.

Are planning to go to EDC Tamico Cup next year again? Just curious, if you will attack a Madcap project for 2WD Retro? I rember reading it somewhere. If yes, we hope for a nice build thread, even if it´s more "serial" than the Fox.

Greets,

Matthias

A longer post coming up. I filled the small slots of free time with developing parts for the Group C series cars, but then was so exhausted and lazy to post it step by step... sorry.

@ruebiracer: The MadCap project will come, but not before next year I assume. The KRv5.2 development for the KleinSerie World Championship is next in line. The Kinzigtal Event is already blocked and the Room is booked. As it has a Kyosho event, @Quincyand I also got new Kyosho cars for it too 

When driving the F103GT some years ago, I worked a lot with the friction-plate-setup. Until today this setup has its fans and it is for me typical Tamiya pan car design. As it also works pretty good, I want to have it on my R91 runner too. It is easy to implement regarding the design, but to make it perfect, it cost more time than thought. This is because the upper pod damper mount differs from that of the F103. Also some parts aren't available any more and I want it to work on more than just my car.

One of the early designs:

The front shall feature a vertical servo position. Unfortunately the links will collide with the upper frame.

A new design, then solved that and got rid of the unavailable aluminum front damper mount:

 

This is how I drove yesterday and proved the concept:

 

Now I wait for the invoice of my manufacturer for the carbon parts.

 

The Porsche was in need of rear wheel covers. These were an easy task and look superb (still need paint):

They press fit so are maybe not good for racing, just show and rolling around showing off 

 

Then I made the diffusor part for the Porsche. This took a lot of hours to get it right. Fortunately the first design was spot on and just needed small detail changes to make it perfect:

 

It consists of three parts to simulate the towing-eye and the air-jack-post.

 

Then it gets installed on the body:

 

The C11 bumper print was outsourced to a friend, who has more skills how to handle TPU material than me:

 

Last saturday Mario and I let our Group C cars fly at Indoor Racing Senden. I am happy how the car handles, but it needs a lot of skill to run it on the limit and hit the sweet spot. The friction-plate-conversion is a must for these chassis in high-grip condition. Marios all stock car was very twitchy to drive in comparison:

 

Had the 956 with me that day to create more attention for these cars as it looks fabulous:

 

All my designs are also available now at Thingiverse for you guys. I even made a friction plate conversion for you to print (and so save money). Check it all out here:

Enjoy!

Kevin, you've taken an already good chassis, and made it great! If you had access to a super speedway, you might pass 100mph!!

This is interesting as I recently found that in very low grip conditions (Desert Dust of badword parking lot), my roll dampers did not make much difference although the car is indeed a bit difficult to drive - but I  might need more practice and more sleep too . I am sure that when I take it to my other spot, the ones that sometimes has very high grip (Sandpaper Courts of Heaven), the car will be faster with the dampers. I am going to convert the rear to F103, mostly to improve the pod lateral balance and the grease roll dampers will go back on since the 3 holes on the forward bulkhead of the F103 pod will make the damper installation straight forward.

What a spectacular set of parts for all 3 Group C cars, incredible! I would love to see that vertical servo mount up close  Are you going to get the white parts re-done in carbon fiber as well or are they staying on the Nissan for good?

Your CAD and printing skills is very inspirational to me and I am sure a lot of other modelers looking at your work from all over the world.

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...

 

now this looks very challenging, and in fact... yes a very nice way to fill up the huuuuge space in front. Will there be any STL files available, please?
Love this thread!!

 

[wtcc5 5773]

@Pylon80: Yes, the white plastic will leave as soon as I find enough people to jump on board the carbon conversion train.

@Fomoco90: I posted the link to all .stl-files above… The aero bumper would need a redesign for a print. I know what to do, but time is limited these weeks.

@all: Please let me know here if there is interest for the conversion shown in the picture below:

 

The grey parts made from carbon will fit plug and play to your Group C chassis. The black parts are 3d-printed ride height shims and white are not included parts. I would need about 20 pieces made for my manufacturer to start. The price will be approximately 50€ plus shipping to your home.

I love the rail to adjust Ackerman 👏

As you know I went to some length to rework the kit plastic parts 😅 so I'll pass on the carbon.

Count me in they look great 

I have 3 shelf Group C's and currently building one for some racing
