I improved the steering axis with some internal changes, now this one consists of 3 U-joints instead of 4.
It's better, but I still have a doubt about the reliability, because everything goes to millimeter and considering the number of joints, I miss a support axis to prevent it from moving during rotations ...
I also made some changes seen on eurobrick :
On the front, replacement of the lights stickers with real lights + addition of a shield
On the doors, addition of a locking system
On the transmission, replacement of two axes of 4 and 8 by a single of 12
