SCX Ferrari 550 GTS with MiniRacingStudios 3DP-Chassis

When it comes to the defining GT1 cars of the early 2000s, this 550GTS surely deserves a place near the very top. It was beautiful, it was fast, and above all, it was strong.

And by “strong,” I do not mean merely capable of producing a single spectacular result. True strength means continuing to win consistently, conquering an entire series, and carrying both the beauty and authority worthy of a true champion. That is exactly what people seek in a GT racing car.

Ferrari’s later official factory project, the 575GTC, had already been modeled by Carrera long before SCX touched the subject. But this is not about that car.

This is about the 550 Maranello that Prodrive developed independently before Ferrari itself became involved ― the one that was genuinely successful.

Considering its outstanding racing record, it always struck me as strange that no slot car manufacturer modeled the 550GTS for such a long time.

SCX finally did, but the result completely missed the car’s defining visual character: the massively widened fenders that made the real machine look unmistakably muscular even at a glance were barely represented at all.

And yet, paradoxically, areas that should have remained razor-low and tightly drawn ― especially the nose ― were instead given unnecessary bulk and thickness.

To make matters worse, the rear wing was fitted with a strangely shaped that did nothing to sharpen or discipline the overall silhouette as a racing car, leaving the whole body looking oddly loose and unfocused.

To use one of my usual expressions, it feels like “something that could never be mistaken for anything other than a 550 GTS, yet somehow looks nothing like a real 550 GTS at the same time.”

Still, SCX paintwork remains undeniably beautiful and extremely durable, so I wanted to avoid any major body modifications involving stripping the paint, reshaping the fenders with putty, sanding everything back down, or completely redoing the livery.

This time, I was casually doing a bit of web scouting to see if any new 3DP chassis had been released, and I happened to come across MiniRacingStudios. Looking through their product lineup, I found a rather unusual anglewinder chassis for the SCX Maranello, and that’s what gave me the idea for this project.

So, from here, the goal should be to build a car capable of running competitively alongside the Scalextric Aston Martin DBR9 I had previously completed using a Slotrax 3D-printed chassis.

For the Aston DBR9, I used an NSR King 25k motor ― rated at 25,000 rpm and 270 g·cm at 12 volts.

Among the spare motors I currently had available was a Ninco NC12. Its official specifications are 23,500 rpm and 270 g·cm at 14.8 volts, which roughly translates to about 19,000 rpm and 219 g·cm at 12 volts.

Still, with more than 200 g·cm of torque available, I figured the final driving characteristics could probably be sorted out through gearing.

The MiniRacingStudios 3D-printed chassis itself is produced from quite a soft material. For racing on my friend’s Ninco track, that should be perfectly acceptable. On a commercial wood track, however, it would almost certainly become excessively flexible and unsettled.

Anticipating that behavior, I chose a 1.0 mm offset anglewinder motor mount in order to lower the center of gravity as much as possible.

To allow proper body float, I trimmed the chassis and glued the front and side aerodynamic parts directly onto the body itself.

At the same time, I also corrected the awkward body proportions ― particularly the overly thick, upward-tilted nose ― by carefully trimming and narrowing the lower edges from the front splitter back toward the side sills, creating a more natural wedge shape from front to rear.

For the wheels, I discarded the clumsy-looking stock SCX spoke wheels entirely.

Instead, I ordered a spare chassis and axle set from the Scalextric Bentley Continental GT3 and adapted its similarly styled wheels for use here. The front shaft was shortened slightly and reused directly as the front axle assembly, while the rear plastic wheels were machined down into inserts to fit Mitoos R9 19×10.5 alloy wheels.

In fact, this was already my second attempt at modifying a 550.

The first time was roughly fifteen years ago, when I wanted something capable of racing alongside Ninco JGTC／Super-GT cars. Back then, I shortened and adapted an anglewinder Supra chassis to make it work.

This time, however, although the car still uses an anglewinder layout, it is built around a Slot.it motor mount system, meaning future maintenance and servicing will remain possible. That gives me some peace of mind.

Of course, the reality is that I will probably be gone from this world before long, so I personally will never perform that maintenance anyway.

And yet, almost automatically, I still build things while thinking ahead toward future modifications and long-term serviceability.

Perhaps it is simply my personality ― or perhaps a habit permanently ingrained by my profession ― but every time I notice myself designing something with future revisions already in mind, I suddenly snap back to reality.

I remember that these little hand-built projects existed only to fill an unexpected extra half-year of time I was never supposed to have.

And when I realize that even these records themselves are part of that, the entire thing begins to feel overwhelmingly lonely and empty.
