Ferrari 643 in 1/43 by Rosso

Recommended Posts

It's been a few monts since I posted on the forum but the group build fired me up to get back to the work bench.

I chose a small subject on purpose, as I wanted an exercise in working with small parts as a way to improve my 1/12 bike detailing skills.

As I had a few 1/43 kits by the long defunct Japanese brand Rosso, it was the perfect kit for the GB.





I purchased a few extras for this kit, namely some extra sponsor decals, a seat belt set and tyre valves. These will probably be tricky to work with in this size...




Here are a few shots of the kit contents. sprues in 4 colors, metal monocoque and lower engine/gearbox, and metal suspenion arms. This kit is the "grade up mannia" version so it comes with a little extra box containing PE radiator grilles and seat harness, a sheet of BMF and some white metal coolant ducts and pilot figure.




The kit was produced in 1992 and looks quite detailed and well engineered for it's age....but there do seem to be a few issues to be corrected. The first one being the cast texture on the metal monocoque. Part of this will be visible on the exterior and I plan to display the vehicle with the engine cowling off, so this texture needs to be sorted out. I chose to sand down the factory applied coat of black paint and applied some Mr. Surfacer 500 which I let overnight to dry and then sanded it down almost completely so only the surface texture is corrected. X-acto knife for size comparison.





Here you can see the corrected monocoque after applying a coat of black primer. As can be seen, there is a gap to the front plastic part that will be filled with some styrene card.




I'm tackling as many small detailing issues as possible prior to painting, to avoid damaging the finish later.

Here are the wheels and the 1/43 tyre valves. Picture taken through my magnifier lamp (as can be seen by the distortion), as the phone camera refused to focus on the valves otherwise. Since Acustion doesn't bother to include english instructions, I had to measure the diameter of the valves to determine what drill to use. It came out as 0.2 mm.....




I've also drilled out the exhaust pipes. Right side is drilled, compared to left side which hasn't been done yet. Easy to do and it makes a big difference.



I'm also looking at improving the bodywork. On the next picture, I have shaved the rear diffuser to a more realistic thickness. Left is done, right not. Again a fairly simple step which I hope will still be visible when the car is finished.



I will also be trying to open the Naca ducts on the bodywork; but these are very small and it's a fairly daunting task as I don't want to ruin the body. So far I haven't started on this yet...




Lastly, I sanded off the moulded-in detail from the radiators and attached the PE radiator faces. 




That's it for the first post; feel free to comment and I'll be back with more soon!

Great start Erik! These 1/43 kits are just as much hard work as larger kits, especially in terms of how clean the result is, I am totally sure you will do this kit justice mate!

Looks like a interesting nice kit!


Tnx Rob, yes I agree so when I found this at a model show last year together with a few other kits from the same brand, I immediately also purchased the Ferrari 642 and the honda NSX (all in the same scale) :D

Tnx Immy! Yes I'm sure that in terms of hours (which I don't really count so it's a guess) this will be same same compared to a 1/20 car. I'm guessing my aversity to building box stock has something to do with that though! :D

I have no clue yet how I'll approach detailing the engine but the mimimum I want to add is ignition cables and I'd like the ferrari name on the cilinder heads as per the original (not moulded in on the kit part and no decal for it either).

We'll see where we go from there.

Hey guys,


A little bit more progress done but not a whole lot due to that I'm doing some work in the house too.

I've mainly focussed on improving the detail in the suspension area. The rear dampers only had their top half moulded and would have been a pain to paint. So I decided to create new ones. They are made up from a pin and some very thin decorating wire wound around some steel wire. Then another pinhead on the other side.

The controls for the gearbox have been simplified to a piece of PE in this kit. I'd like to add the controls wich look fairly complex and with a lot of wiring; but I haven't figured out yet how to represent this realistically without too much work. And it still needs to look decent of course. Or is my detailing OCD going a bit over the top here? 



In the front it's the same story. The dampers look half decent but they would be difficult to paint and will deffo look better as separate units. 

The base is some 0.6 mm steel wire found at florists (they normally look green and are used to wind around the stems of flowers). I then widened the inner diameter of a 1 mm alu pipe so it would slide over the steel wire. on one end I glued a piece of black hose, on the other end some 0.6 mm shrinktube. At the front end I soldered on the linkages to the rollbar. I still have to recreate the front suspension rockers which have been omitted in the kit. I've thinned a small piece of plastic card and once cut to shape, I will put some PE rivet on top to represent the pivot point. 



As you can imagine this is all very fiddly work and I'm anxious to see how it will look like once assembled. 

I hope to start painting in a week or two as there is a lot of CF to apply too...

Thanks for watching and feel free to comment!

Nice progress Erik! Such tiny parts, I think you are doing some really great additions and modifications (I dont think you're going over the top!)


How are your eyes doing? :P

Just got to looking at this one. Those air valves ?. I thought the 1:24 ones were small!  I’m loving the extra work you are doing, and in such minute detail!
