Building and detailing the Meng McLaren MP 4/4 1/12 scale

By Mark Laird  

I have seen many people building the 1/12 scale Meng MP4/4. Since this car held the record for the most wins in F1 until the end of the 2023 season, when the Red Bull RB19 claimed that title, it's a car I've always been interested in building. After admiring the work of others on their models, I decided to take the plunge and purchase one myself. With over 50 years of experience building models, I couldn’t resist the urge to customize it rather than assembling it straight out of the box.

I have seen many people building the 1/12 scale Meng MP4/4. Since this car held the record for the most wins in F1 until the end of the 2023 season, when the Red Bull RB19 claimed that title, it's a car I've always been interested in building. After admiring the work of others on their models, I decided to take the plunge and purchase one myself. With over 50 years of experience building models, I couldn’t resist the urge to customize it rather than assembling it straight out of the box.


Editor's Note: This tutorial is focused on adding details and improving the model, and not on the construction itself, which can be seen in many places here on the web. For this reason you won't see many images of the basic construction.

That being said, if you're not someone who displays F1 models with the cowling removed to reveal the intricate details underneath, this model is an excellent choice. It's very well-engineered with a precise fit, although in some instances, it might be too precise, as I'll explain later.

However, if you're a modeler who enjoys showcasing the detailed components under the cowling, this model falls a bit short unless you're willing to add your own detailing. Personally, I fall into the latter category. I enjoy studying real-life photos of the car to identify as much detail as possible and then replicate those parts in the model. Additionally, I've downloaded a copy of the 1/12 MFH MP4/4 instructions to use as a reference for parts and placements not included with this model.

In today’s world, detailing these models has become much easier, thanks to the plethora of companies offering various parts. Brands like Top Studio, Detail Master, RB Motion, MFH, Hobby Design, and others provide nearly everything you could need for model detailing. They offer everything from comprehensive detail kits packed with intricate parts to essentials like decals, nuts and bolts, electrical fittings, PE parts, 3D resin parts, wiring, tubing, and more. If you can't find what you need, you have the option to hone your skills and make it yourself. Whether you utilize mechanical tools such as a lathe, mill, or 3D printer, or employ basic scratch-building techniques, you can incorporate the details you find in your reference pictures into your model. Practice makes perfect; the more you engage in scratch building, the more proficient you become.

One aspect that many modelers may lack experience or practice in is the application of carbon fiber decals. Fortunately, this kit includes very nice pre-cut carbon fiber decals. I'll delve into some tips for applying these decals later on.

As mentioned earlier, there are multiple companies offering parts to enhance your model. I have amassed quite an inventory of parts from previous builds and have purchased many different items to incorporate into this model. I prefer to sit down with the instructions and my reference photos to create a list of the aftermarket parts I intend to use for the build. By procuring them before I start the build, I can focus solely on the construction process without any interruptions.

For this particular build, it was evident right from the start that there were no tobacco company sponsor decals included in the kit, as model companies are prohibited from including them due to classification as toys. Therefore, at the top of my list was a set of Marlboro decals, as these cars were famously adorned with the Marlboro livery. Many companies produce Marlboro decals, but they vary significantly in price. Over the past couple of years, I've been using Decalpool decals for my models. While they have a limited selection of vehicle decals, they do offer ones for the MP4/4. These decals are of good quality, featuring professional waterslide application, and each decal has a definitive border around it, eliminating the need for precise cutting from full sheets. This border allows for rough cutting, after which you can handle the decals with tweezers without directly touching them, only handling the backing.

Here is a listing of the extras used to build this model

As mentioned earlier, this model is exceptionally well-engineered. One notable aspect is the unique way the parts are attached to the sprues. While some parts attach conventionally, many connect from the underside, where they will be glued or matched to another surface. This design facilitates painting with the parts still on the sprues. After painting, you simply use your sprue cutter to remove the piece, then file down any leftover sprue material on the edge or side that won't be displayed, without affecting the visible part of the piece.

Another distinctive feature of this Meng model is the tight tolerances between the parts that need to fit together. They fit snugly right out of the box, but when painted, the additional thickness from the paint can sometimes prevent the parts from fitting together properly or make them so snug that separating them without damaging the part becomes a challenge. Consequently, quite a few parts weren't glued due to this issue. If separation of the parts was necessary, it required filing, sanding, or drilling the paint off the parts before attempting to assemble them. Additionally, the plastic used in this model seems slightly softer than that of other styrene models I've built in the past, which may contribute to the tightness of the parts.

The model as an out of the box kit is simple and straight forward. To find detail items I use reference pics, plus 1/12 scale MFH MP4/4 instructions for additional references.

Superdetailing the Tamiya Honda NSR500 1984 – 1/12 scale This article is about the assembly and detailing of the Tamiya Honda NSR500 from 1984, using the awesome Hobby Design detail set and other aftermarket stuff, such as rivets, bolts heads and so on. The model is a recent release from Tamiya, and the detail of the kit is astonishing. Given the very peculiar characteristic of this motorcycle, as the fuel tank placed below the engine, and the exhausts infront of the driver’s chest, I decided to show the cowling not placed on the chassis.

Building the Wingnuts Wings Albatros D.V #32009 - 1/32 scale If I had to choose my favorite aircraft from the WW1 era, it would have to the Albatros D.V.

Add the four different colour schemes included , with more on the way, makes it a must buy for the discerning modeller.

Building the Bronco M-24 Chaffee 35069 1/35 scale My dear friend, J.J Aos, who is himself an encyclopedia, gave me all the necessary information to place it in Pakistan. Although it is common to find pictures of Chaffles of late production, the early ones were also seen, included in the last Pakistan's 1971 conflict with India. Of course, exactly when I finished my model painting, Bronco Models offer the final release, Have you heard of Murphy’s law…?

Building the Tamiya Mitsubishi A6M3 Zero 1/48 scale The model is characterized by a good level of details and an excellent level of accuracy. The build was done without any special issues. I assembled it directly out of the box except for two minor additions: Eduard WWII seat belts for Japanese aircraft and Eduard canopy mask for A6M3 – EUEX318, although the kit included canopy masks, but I was not aware of the matter when ordering the kit.

Defender of Stalingrad or how to make winter camouflage Tamiya 1/35 scale To build this model, I used the old Tamiya´s T-34/76, 1943 kit. Although its moulds are from the eighties of 20th century, it is still good and with nice detailing. This article is intended for newcomers to armor modelling showing how to make a winter camouflage.

Kitbashing the Tamiya Ferrari F40 photo array 1/24 scale We use to publish large tutorials plenty of pictures and large texts, but when I saw these pictures I realized that this probably wouldn't need anything more, sometimes happens. Looking the pictures I understood all the process… besides not always contributors want to spend extra time writing, when already inverted thousand of hours building taking pictures…etc. I hope you enjoy the pictures as I did, thanks Geo!

Building the VW 1300 Beetle 1963 - Herbie - Tamiya 1/24 scale The Volkswagen Beetle is undoubtedly one of the most popular cars in all the history. The attractive and singular body’s shape has turned it into an icon in our recent history. At the end of the 60s, Disney Studios decide to immortalize the small car taking it to the cinema screen in Herbie, a movie in which this beetle played a central role and five sequences came later. The first movie The Love Bug which was known in Spain as Ahí va ese Bólido, was premiered in 1969.

Building the Bandai Star Wars AT-ST 1/48 scale The idea of assembling and painting this model was swirling around in my head since some time ago. It’s one of the vehicles of the saga I like best and besides, Bandai, the brand that introduced it on the market, is a very recognized one for manufacturing excellent models with “snap” perfect fit without the need of glue and highly detailed.

Improving the ZIL-157 – Trumpeter #1001 1/35 scale The Zil 157 is par excellence perhaps, a general purpose cargo truck and troops transport and for its performance it also served as the tractor for the SA-2 missiles. Although its production stopped many decades ago, still it can be seen in several countries. One of the users of this truck was Egypt and this is the version I decided to do.

Building the Porsche Turbo RSR 934 Jagermeister – Tamiya #24328 1/24 scale It was in 1978 when I saw for the first time, the Tamiya Porsche 934 at a hobby shop. Though, the 1/12 model was built straight from the box and without paint, the details seemed to be surrealist and impossible to imagine up to that moment. It was my first approach to that Tamiya kit in 1/12 scale. Perhaps, with the aim of re releasing that success, several years ago Tamiya manufactured the same car, winner of so many championships, but in 1/24 (the most popular scale) which is the subject of this article that aims at helping the less experienced modeler to build the new Tamiya Porsche.

Building the Fujimi Mazda RX7 Greddy 9 - 1/24 scale On several occasions, when surfing around HLJ, I saw the Greedy 9 on sale. To be honest, the tuning aspect of the art box showing this magnificent green Mazda RX-7, tempted me more than once, but it didn’t get me very excited cause in the short description of the kit, I realized that this is one of those models which doesn’t feature a detailed engine, and this is exactly, what I like, to get detailed engines. But, in the end, that tempting picture of the box really convinced me, thus I ordered it.

GAZ 66, building it as a tactical truck Revell #03051, 1/35 scale Since time ago, I’ve been thinking to add a wheeled vehicle to my Middle East vehicles collection. Looking for an interesting kit, I found the Revell Gaz-66 (ref.03051), which is also marketed by Eastern Express. However, after investigating, I realized that there were just a few versions to accomplish Quite apart from the soviet green, there was not much to play.

Building the Tamiya Mercedes 300SL #24338 1/24 scale Looking at the photos of a real 300SL body, we find out Tamiya have made an excellent work. However, it’s possible to go even further and give the body of this Mercedes an additional touch of realism. Regarding the chassis Tamiya also made a hard work with the tubular frame, very realistic indeed! besides of being quite simple to assemble. The engine and cockpit are not far behind. To paint this marvel, I chose silver that is unavoidable for this beauty. So, the aim of this article is to share with the reader the building, painting and weathering process of some parts, in such a way that they can be reproduced by a modeller with a minimum of experience.

Building the Lancia Stratos HF Rally #4 Pirelli 1978 San Remo - Doyusha 1/12 scale Doyusha offered both in the 90s and later only the Monte Carlo’s, making finally the San Remo Rally with the Pirelli team livery. I’ve been trying to get this kit but it’s discontinued although still it’s possible to find it from some online stores/shops and on ebay. I bought one that had been partially built, which involves double work, missing parts, etc.  This article aims at sharing with pictures the experience to rescue and old odd kit, improving it to the best of my skills.
