While we may think of these Bugatti’s as beautiful and very retro, but also rather slow compared with modern racing machines; in their time they were, of course, built for speed with their cutting edge motor racing technology of the day.

With this thought in mind, the 1/32 models deserve well engineered motor racing technology too. And that should include a low friction transmission.

As we mentioned at the outset of this thread the spring based universal joint is a difficult starting point for the digital conversion. A ‘spring centred’ implementation of a universal joint onto a short propshaft end section is an awkward configuration for a propshaft which is designed to centre the entire rear axle. Add to that some misalignments of the propshaft bushings and the result is a transmission which is quite difficult to turn. This is hard work for the motor and the excess friction generates excessive braking effect too. No spooling down as the motor power is cut. Instead an instant stop.

The new transmission as reported in the above posts is silky smooth - just as the transmissions of those 1930’s full size Bugatti’s will have been :)

A worthwhile upgrade IMO.
