Airfix 1/24 Peugeot 905 review

Heller 80718 (1992-) Heller 80178 (2011-) Airfix 06419 (1993 to 1996) Gunze Sangyo GX-419 (1993)


Bad reputation

Heller issued a 1/24 scale model of the Peugeot 905 in 1992, followed by an issue of the same model by Airfix in 1993, and the same year it was reissued by Gunze Sangyo. Among builders of sports car models, this kit is often mentioned as a model that is very difficult to build, and actually not worth the trouble. For example, Bill Via commented: "The Heller 905 EV1 Bis kit is the absolute WORST kit I have ever seen in my 30+ years of building kits. Out of 1000+ kits I've built during my entire life, it's the only one I simply could not fix and ended up throwing it away, not even saving anything from the box for my parts stash. Not only should this kit be shunned by moderate builders, but folks who can scratchbuild should leave it alone as well. I've had two of them (the purchases separated by 5 years) and the only good thing about them is the boxart." Bill described the following problems of the two Heller kits that he owned:

  1. Every flat panel is warped (chassis pan, body coverings)

  2. Every curved panel is warped (driver greenhouse, engine coverings)

  3. Parts not symmetrical: left side parts are smaller, shorter, more curved than right side body parts

  4. Angle of chassis pan incorrect to angle of all other body parts, you cannot close the body if you build it off the chassis pan

  5. Tires were rectangular in cross-section, almost a perfect 90 degrees from the tread to sidewall transition. Opening is too small to fit over wheels

  6. Glass is undersized for the opening in greenhouse

  7. Decals exhibit Moire effect and fall apart when introduced to water

Bill's review confused me greatly, since my Airfix kit didn't look too bad, and dry-fitted reasonably well. It's not a great kit, but it looked far from unbuildable. It took a long time before it became clear where the confusion originated. It appears that there is a large quality variation with this model, both in the Heller and Airfix packaging, and that this can be attributed to the injection molding process. This process has lots of variables, such as mold temperature, material temperature, pressures at several stages of the process, and injection and cooling times. Mike Kendel commented that problems 1 through 6 all could be caused by the injection molding variables. Even with a perfect mold, the wrong set of variables can produce bad products. Back in 1992/1993 when this kit came out, Heller did all the molding of Airfix models. It can therefore be assumed that both the Heller and Airfix versions were made in the same injection molding plant. Possibly the kit's molds required a very specific set of settings, and that these were not always adhered to. It's most likely that Heller produced good and bad batches of this model.



Model development information

In the combined 1993 Airfix/Heller catalog, the Heller part contains some information on the development of this model:

On the 15th of October, 1992, the injection moulding machines in our factory produced the first set of parts for the 1:24th scale Peugeot 905 EV1 Mark 2 [French text says EV1bis]. This vehicle is the very latest state of the art in sports racings cars and it shows that we, at the Heller company are always in the forefront of the model industry with new kits.

3 days later, on the 18th of October at the Magny Cours race track, Mr Jean Todt, Director of Peugeot Sport, was presented with the first completed model.

The initial idea to produce a model kit of the car to final production took 7 months, an amazing number of hours had to be dedicated to the project to get every detail correct. 4 visits to the Peugeot Talbot Sports factory were required by our research team and then 800 hours of computer aided design to produce a full range of drawings from the rear spoiler to the v.10 engine. It then took another 3,000 hours to manufacture the mould tool of 95 parts, which includes 41 for the engine alone, to the highest standards of precision.

Each year we endavour to produce better and more accurate kits so that our models become "always true to life".



Warped or not?

I shot the following photographs of my dry-fitted model to show that points 1-3 and 5-6 don't apply to my Airfix kit. Bill Via commented: "My two examples were NOTHING like the photos of yours". The monocoque could be slightly too tall (point 4), but I haven't tried reducing its height.

The monocoque has the front suspension attached, and that makes sanding after assembly difficult. I removed the upper and lower wishbones from the monocoque parts, and put pins in the wishbones for easy reassembly. Then I assembled the two parts that form the lower side.


The main bodywork fits relatively well without tape. Closing the gap between the sides and the floor deforms the floor slightly. Maybe this can be solved by removing around 1 mm of the monocoque's height. As far as I can see, the engine will accept this drop too, since there is some space between the sump and the floor panel.


Some gaps exist between the monocoque and the bodywork.


The lower nose part (#14) was described in one review as being 2 mm oversize on both sides. Yet it fits relatively well here.


The rear bodywork fits reasonably but could use some fine tuning.


The transparent parts fit well, except for the door window on the rear side, which shows a step.


The engine air inlet also fits well even when just dry-fitted, contrary to complaints by other modelers


The floor panel seems to lack a cover for the gearbox and some vanes in the tunnels.


The wheels fit perfectly in the tires, but lack a locking nut. The tires are glossy and feel like plasticised plastic.


What version is it?

There is some debate whether the model represent an 'Evo 1' or 'Evo 1 Bis'. The problem starts with the question whether there ever was an 'Evo 1'. The book 'World Sportscar Racing '91' from late 1991 calls the model introduced at the Nurburgring race on 18 August 1991 already an 'Evo 1 Bis'. This suggests an 'Evo 1 sans suffix' was not raced. The model manufacturers contribute to the confusion by calling the same model 'Ev 1' (Airfix, Gunze Sangyo) and 'Ev 1 Bis' (Heller) on the box top.

In 1993, parts of the never-raced 905 Evo 2 were fitted to the Evo 1 bis, including transverse gearbox, rear suspension, bigger tunnels. The bodywork bulge around and behind the engine became larger and rounded. The rear brake inlets moved inboard a bit. The exhausts were rerouted from the sides to the venturi tunnels. This version is sometimes referred to as the 'Evo 1c'.

However, the designations that Le Mans Miniatures uses for their models is 'Evo 1' for the 1992, and 'Evo 1bis' for the 1993 model. Heller started producing their kit in 1992, which includes decals for a 1991 car, and the box says 'EV 1 BIS'. That shows that the 'Evo 1 bis' designation was already used in at least 1992, and not from 1993 on.

Based on this information, I believe the model correctly represents an 'Evo 1 bis' version.



Problems / room for improvement

The kit has some problems, and has room for improvements:



Alternatives

Profil24 produces two resin 1/24 905s: 1992 Le Mans Evo 1B (P24004) and 1993 Le Mans Evo 1B (P24005). They are curbside models without engine details and a one-piece body. They feature headlights and the front fender louvers are closed but positioned correctly. It is reported that the model is based on the Heller/Airfix kit, but a couple of parts are integrated and some are changed to meet new specs. For example, the 1993 version has an extended bulge on the engine cover, the exhausts are deleted from the sides and the rear brake inlets are closer to each other. It is reported that the Profil 24 models are more accurate than the Heller/Airfix kit. One improvement that I see is that the main inlets are wider, and partly go under the top of the body. Also, these models have details of the pins and clasps that fix the removable bodywork parts on the 1:1 car.

Spark / Redline issued a 1/24 die cast Peugeot 905, the Le Mans 1992 winner (catalog number 07-2008). This model is based on a Le Mans Miniatures master.



Museum examples

Seven Evo 1 chassis were built according to Martin Krejci's chassis number list. Museum examples are reportedly to be found here:


Around 2011, some cars appeared on the tracks again, for classic racing. The following was compiled from limited data, so it might not be 100% correct.



Decals

Decal options of the kit-supplied decals are:

Aftermarket decals are limited to two suppliers:

Airfix Skunko Patto's
