Ferrari 250 GTO Chassis . A Ferrari ? Really ? From Mr I-only-do-slow-cars ? Blame De Tomaso Pantera... .
I can explain; this is a commission build - Tom's commission - and he asked me to contribute. I built this chassis and took it over to Tom's house where we built the body together. After two days' wrestling with an ever-diminishing pile of little red plates we had something that looked like a 250 GTO.
Beats working for a living... :-)

A quick word about Tom - an excellent man - and his Bird Project on Cuusoo. I've seen and handled these models in the plastic and it would be a crying shame if they weren't made as sets for everyone to enjoy. They are fantastically good. Support them by clicking the link above. Do it now.
This chassis features the obligatory V12 engine, driven by the rear wheels via a forward / neutral / reverse transmission, working steering, double wishbone front suspension and a leaf sprung live rear axle.
Sweet 'n' low.... reasonably rigid, as well.
The dashboard, a fairly sparse affair on this most focused of Ferraris, and the classic six fingered gate for the gearlever; although it only moves along the centre slot to select forward or reverse gears.
Some Ferrari-like detailing. That strut across the spring mounts is there on the real one and necessary on the model. The single hard spring per side wasn't enough with the weight of the body but it was simple enough to add another one...
Now then, steering. Pay attention. Most Technic car builders make the effort to include Ackerman geometry, whereby the inner wheel turns more than the outer to compensate for the smaller turning radius. However, most post-war high performance cars do the opposite - the outer wheel turns more to compensate for the greater slip angle on the more heavily loaded wheel. That's what I've done here. This is a high performance car, after all....
... although you wouldn't think so to look at the rear suspension. 300 bhp and leaf springs ? Really, Mr Ferrari ? Apparently so, at a time when, say, Jaguar were using a much more sophisticated set-up on a car that cost a third as much. Enzo always said you paid your money for the engine, the rest of the car comes for free... still, at least he made the effort to locate the axle with a Watt's linkage - that's those joints and axles behind the diff...
$$$$ ££££ Several billion Lire....
Building this was fun - thanks to Tom - may there be many more!
Now if you don't mind, I really must build something to trap this little fella for my Moc Olympics R2 build. Humanely, of course...
