Honda RC213 V '14 REPSOL Tamiya 1/12


Recommended Posts

Hi Olivier

Obviously the RC2013V of 2014 had a carbon fairing

https://motogp.hondaracingcorporation.com/rc213v-2014/

Bodywork

The lightweight carbon-fibre bodywork plays an important role in making the RC213V as aerodynamic as possible. The 2014 RC213V has a modified fairing to reach the maximum compatibility and performance between handling and drag.

 

and in addition in the link of the article you have lots of photos of the moto GP  😉😉

Thanks a lot gamblor916 for these great pics, even if they plunge me into the greatest perplexity!

Unlike you, I am far from being a specialist in bikes, GP etc.

Your pics suggest that, finally, it is very possible that the inside of the upper cowl was the same in 2014 than in 2018, while I have just removed the carbon decal and repainted Flat Black this inside!!

More, you could find pics showing the inside of side cowls:

I could find a carbon decal that could be more appropriate than the Tamiya one to represent this yellowish carbon kevlar:

Of course, I could also use the painting option with the stocking (with lemon yellow instead of Gun Metal)...

 

And the Honda Repsol bench, showing a mechanic in nearly the same position than mine, is also inspirating for my project:

Well, my friends, I'm learning a lot with you two!

Thanks so Manu for this link, which confirms that the bodywork was made of carbon fiber:

I had found this HRC site while I was looking for pics and it contains indeed many great pics (none of the inside cowls, pity), with the major benefit to show the 2014 version (among others) and this for the 2 drivers, Marquez and Pedrosa.

It is mainly these photos that I was referring to in my N.B of yesterday post, but I missed the bodywork chapter...

Curious if so that the article you put previously in link suggested that the use of carbon for the fairing was experimental in 2017.

I don't understand that. Do you?

My friends,

 

Considering the new docs and infos brought as well by gamblor as by Ghost69, and the comparison below, here is what I will do, first on the upper cowl, and probably on side cowls too (partially):

 

spacer.png

 

For the Yellow Green, the XF-4 Tamiya will be used.

 

To be followed...

I now think my first link is to be taken another way.
"Le carénage beaucoup plus radical en carbone" certainly speaks to the aerodynamic shape being more radical...regardless of the materials used.

 

Carbon is sharp and brittle, it does not only have advantages, which is why carbon rims, for example, are prohibited.

 

While we're on the subject of carbon, another very interesting link on the big checkerboard carbon.
https://www.paddock-gp.com/technique-motogp-le-carbone-a-gros-damier/
I had an industrial client who weaved carbon fiber and when you had approached the carbon rendering I wanted to point out to you that depending on the weaving used we did not have the same rendering at all and sometimes we are far from the "basic" representation that generally found in model making.

Sorry, it doesn't help you much but the subject is very interesting

Your work is superb 😉😉

Thanks again a lot, Manu, for the explanation about the article (you are most likely right, it was referring to the shape rather than to the material), for the additive link and for the kind words. 

Just a precision: the stocking would not be convenient on the very concave surface I have to deal with inside the upper cowl.

I have just ordered the Gravity carbon fiber box set, including 3 grades of 8 x 8 cm nylon mesh that should be much better imho.

Other precision: on second thought, I will lighten a bit the XF-4 with X-2 and X-8...

Hello chaps,

 

A new update:

The job on the outside part of the upper cowl is on the way, nearly over (pic this afternoon). I ever removed the wrong notches inside and applied the Yellow background. I will have to be patient as I should get the nylon fiber until about 10 days. 

If gamblor916, or anyone, could find me a pic showing the inside of the Honda Repsol side cowl, it would be absolutely great, of course...

 

Cheers, O

Photos of the inside fairing are extremely rare. When you see them off the bike they're usually placed with the outside up, likely to protect the finish from scratches. These are from 2006 and show the same yellowish carbon. It's likely following year models will have the same look. I'd use something like this to replicate it.

It's logic indeed and it is so that they will be exposed in my little "scenario". That is why I will represent the inside of these side fairings quite simply, but though with the carbon kevlar.

In this regard, thanks a lot for the link to the carbon kevlar decals on Spotmodel, the 1/20 SK decals look good, I could order them for the side fairings inside unless I use the painting option.

On my side, I just got the Gravity Carbon fiber box set and I decided to apply a different option than painting to represent the weave fabric inside the upper cowl that is not plain. I will indeed use the intermediate grade (among the 3 grades of nylon nets provided) not as mask but as material itself, glueing it on the Yellow background.

To do that, I first applied on the net a coat of Gravity Dark Surface Primer, then 2 coats of Dark carbon fiber basecoat (included in the set).

Then I used a wide masking tape (50 mm Tesa) to create a pattern of the upper cowl inside:

 

spacer.png

 

Then I used this pattern to cut in double sided tape (Pocher) and in the nylon net the shape of this inside.

I could so assemble the Black nylon net inside the upper cowl, getting the desired weave fabric look, not plain:

 

spacer.png

 

N.B: not only the net is too shiny, also the clear dst...

 

But I am gonna need your help one more time:

 

spacer.png

 

I have also been working on the logo:

 

spacer.png

 

A posteriori, it appears that the decal is a bit too small (4,7 mm diameter). I will print it a little bigger (5,1 mm diameter). 

So, the "Chrome" ring will be narrower, closer from truth...

 

Yesterday afternoon, Internet didn't work in my area, and I couldn't post the pic showing my upper cowl as mentioned in my previous post. Here it is:

 

spacer.png

 

Well, things go slowly but quite surely. I hope this first Honda Repsol (the Pedrosa one) will be over in September, October at the latest. I got yesterday the kit for the Marquez one…

I want to thank again all of you, especially the ones who gave me a hand and the ones who encouraged me by liking or writing nice words…

I apologize for not taking the time to see other builds in the forum, but if I don't spend the few time I have to go on with my own build (and to share it with you in this thread), it will become so slow that I will give up.

 

Cheers, O

Waooh, again a great pic, gamblor, thanks a lot!

It brings interesting infos:

 

spacer.png

 

Notice that this carbon has a tiny pattern, that is why it is visible only on this close-up. Considering the 1/12 scale of the build, the question to represent it or not may is pertinent. If it is decided to represent it is taken, the 1/48 scale carbon fiber plain weave (Scale Motorsport) is a good choice, as its pattern is tiny. Personally, I have not taken such a decision up to now but I don't exclude to apply portions of this decal on the Black lower area of my upper cowl.

About this A12 part, it seems to be quite correct. The fact that Top Studio suggests only to modify it (see above my february 2 post p. 3) leads me to trust in this proposition, still without knowing if logically, it should be assembled on the uppercowl. In the doubt, I will assemble it.

Yet,  precisely, if I wanted to assemble it on the upper cowl, I had to remove the lower portion of the weave fabric, the thickness of the nylon being an obstacle to a fine assembly:

 

spacer.png

Cheers, O

 

Edit a bit later: I decided to apply the 1/48 carbon decal mentioned just above on the bottom part of A12 first, to see if it is worth it to apply it more widely. The great close-up gamblor brought leaded me to reconsider the option for another area:

 

spacer.png

 

In a previous post (July 23, previous page), I said this area should be painted Anthracite Grey. I could decide finally to rather apply the 1/48 carbon decal, what will be a challenge considering the complex shape of this bottom rear cowl...On the other hand, applying the Anthracite coat without affecting neither the inside (Silver), neither the upper surfaces of this rear cowl, is not so easy too...

 

I also went on with the fuel tank cover, that is now over:

I personally used a brand new 3000 grit Tamiya sponge with care to get a smoother limit.

Hello chaps,

 

If you remember, I had replaced advantageously the Tamiya decals screws by GSW ones on my front fender (last May 19 post p. 8).

I had tried to find more same screws in the jar where all my GSW micro screws are stored, but I could find only 2 ones among the probably 1000 screws.

I wanted to order another set on the GSW site but pity, they remain out of stock from May up to now.

I supposed I could find some other same screws if I decided to patiently sort all the micro screws and I was right: I could find 17 screws, what should be largely sufficient at least for this first bike, especially if you consider that some screws will not be in place, logically:

 

spacer.png

Of course, I should have done all these corrections before painting my upper cowl. As usual, I was too much of a hurry and I realized too late. If necessary, I will remove all the paint and redo the whole painting job on this upper cowl...

 

Cheers, O

I think that mesh inside looks a bit too thick. You should spray metallic black over it to get that pattern then remove it. I think you can get a good result from that.

For the silver just use any thin foil. I think it looks better than paint.

I suppose you talk about the nylon net. I think you are right, it is indeed a bit too thick. I may try the option you mention here, or as well the carbon kevlar on Spotmodel you put in link previously.

Here is my strategy: I will first try to avoid redoing all the painting job. I drill the holes (0,7 mm) in which the tiny screws holding the windshield (head 0,9 mm diam.) will be inserted (replacing advantageously the little Tamiya bulges), I remove the bulges relative to the screws 5 and 6, I fill the Tamiya holes and manage a little hole (0,7 mm, as mentioned). A thin coat of White as base coat is necessary before applying again the Fluo Orange:

 

spacer.png

 

If things go well (Fluo Orange OK), I will follow your suggestion, gamblor, spraying a Black coat on the mesh inside (masking carefully the outside...) before removing the latter. If not, I will redo completely the painting job on this upper cowl…

 

Edit a few hours later: the good new is that the correction on the Fluo Orange is OK. The less good new is that spraying the Black with the net in place inside was not good when removing the latter. I recall that the net had been applied using a thin (0,05 mm) dst and so, the Black was sprayed on this dst.

I decided to remove the dst, I found my previous Yellow background and I tried again to use the net (not glued this time) and apply again Black. Result a little better but not good enough:

 

spacer.png

 

I decided to order immediately the ones 1/20 carbon kevlar SK decal mentioned above. I think this should allow to get a neat result. The hardest will be to avoid folds, while I have to deal with a very concave area... But maybe I will though make a last attempt with the painting option…

 

Cheers, O

Hello chaps,

 

As I said at the end of my previous post, I made a last attempt. For the latter, I decided to rather use the biggest grade among the 3 nets provided by Gravity in the carbon box set. Indeed, the doc below (provided by gamblor, as many other ones) shows that the carbon kevlar pattern is quite wide here (we could see that the carbon pattern may vary a very lot following the parts):

 

spacer.png

 

spacer.png

 

spacer.png

 

N.B:

- I could thin a lot with alcohol since I used Tamiya acrylics (X-18 and my mix XF-4/ X-8)

- I said in the label that this upper cowl inside would be nearly invisible. In fact, depending the way I will place the fairing, it could be more or less visible:

 

spacer.png

 

Notice that, on a pic gamblor showed above, the upper cowl is placed upside down. Pity, we can't see it better, it would be very interesting:

 

spacer.png

 

Considering that, following the way my upper cowl will be placed in my "scenario", I decided to do the merciless comparison:

 

spacer.png

 

 

 Cheers, O

Your bravery in going back and amended parts that you've already done a lot of work to is, well, admirable. 👍

 

I myself use the old lit firework adage: never go back to it!

Thanks slippers for this kind comment and welcome in the thread!

gamblor was right, my idea to use the net provided by Gravity was finally not good, as it leaded to get a too thick weave.

In fact, when I read him saying so, I was ever wondering myself if I should go on with this option.

It's true, I am able to all patiences to get the best result I can get and with my favorite hobby. I assure you I have not the same patience for everything 😉!

Yes, Jochen, it's me and I'm fine, thank you!

In fact, I am redoing (or rather improving) the painting job on the outer part of the upper cowl, but without having to remove the paint with a Paint Remover, and that is precisely what I wanted to avoid...

The many trials on the inside leaded to little defects outside (visible on my last pics if you look closely), what I obviously couldn't stand:

the Fluo Orange, the White strip and the Fluo Red are ever improved and OK now.

I am redoing the left side of the lower White area (the right side is ever done too):

 

spacer.png

 

N.B: These complementary coats are thin.

 

For the lower "Black" area, we could see thanks to gamblor that it is in fact carbon with a tiny pattern. My decision about the way I will proceed for the latter is not taken: I would prefer a painting option a priori. If so, the most simple would be to add a pinch of White to my Black, providing a very Dark Grey that is more faithful than the Black I applied previously. Honestly, considering the scale, the tiny pattern is nearly invisible, and only a close-up allows to see it. Another painting option would be to use the smallest grade of nylon net (pre-test required as the pattern would probably be too big).

I would prefer to avoid the 1/48 carbon decal for this area but it is a third option.

 

Cheers, O

Hello chaps,

 

I said above I would add a pinch of White to the Anthracite Black to get a Dark Grey. I had a better idea, mixing both Gravity carbon paints included in the set (ratio Dark 75% Light 25%) without using the net.

The result is nice, and the comparison with the 1/48 carbon decal shows very comparable results:

 

spacer.png

 

N.B: the great Gravity Clear coat (to come) should highlight a bit the metallic pigments of this mix and improve so the result ever acceptable.

Hello my friends,

 

A new update for the upper cowl:

 

spacer.png

 

If someone knows where I could find tiny screws (still out of stock for months on GSW), thank you to tell me!

A bit later, the windshield was assembled on the upper cowl with Testors white glue:

 

spacer.png

 

Cheers, O

 

Edit later: I finally found tiny screws and hex nuts, on RB Motion. Quite expensive, I hope they will be fine...

Hello chaps,

 

I'm afraid I am going to redo completely the uppercowl. Indeed, drilling 0,7 mm holes and inserting 0,85 mm diameter screw heads inside was a total mistake, the latter being much too big compared with the really tiny screw heads, as the merciless comparison below confirms:

 

spacer.png

 

A close-up allows to say the screw heads diameter should be about 0,5 mm imho. I will have several options to represent these screw heads (I ordered 0,51 mm diameter ones on RB Motion yesterday, but I could also cut 0,5 mm tin rivets with my RP Toolz Rivets Maker:

 

spacer.png

 

Of course, I know some will say that redoing the full job while no one would have noticed this error is a pity, but sorry, I have tried to be faithful on slightly visible details, yet this upper cowl, especially on its outside, will be particularly visible and consequently, I can't stand keeping it like that. 

I will take advantage of this repair to further improve the Tamiya part: it remains indeed too thick imho in general and particularly by places...

 

Cheers, TMO

Your attention to the smallest detail is second to none, I would not have the patients to go to the levels that you do.

I know that a superb replica will be the end result of all your hard work!
