Default The ultra compact driveshaft " Real Constant Velocity "

Ste MiBorg began seriously considering the possibility of producing a new generation of shaft for our cars, This French Ste filed patent n° FR 12 59048
For the shaft RCV : Ultra compact miniature shaft
really "CV"

First pictures
« Principle possible for our cars Scale and Crawler»
The idea is to use this with HUB / BUH Vanquish without touch (almost)

Very neat idea but I assume there's some springs or other type of centering component missing from the assembly photo? Otherwise the double joint won't stay centered on the axis of rotation.

Xray did something very similar in touring cars - possibly other companies as well.



Not sure how French patents work, but in the US if it exists, you can't get a patent on it, unless fundamentally different.

i have seen these somewhere as well. i think maybe tamiya has them for the high end TC's.

Tamiya 44mm Double Cardan Joint Shaft (DCJ) Shaft Kit (1 Pair)

and look here, 30 seconds on google and here you go. i think they have been out for a couple years now.
