Hello, after a long pause I decided to begin a new project, another high speed chassis, but this time I wanted to build a chassis with proper driven independent suspension and lighter than my previous build. After many attempts in the past, I concluded that this wouldn't be possible without printed pieces, as lego u-joints just can't survive the shock load of 4 buggy motors. My previous MOCs either had solid driven axles or suspension using only one u-joint, which didn't have ideal handling. Now, after testing efferman's 3D printed CV joints (coupled with Lego spherical gears, similar to 8880) on a small MOC, I used them on this large scale project. Results - it works! They easily handle the power and CV joints are more smooth in general. There is still room for changes and even after these pictures were taken I reinforced the rear suspension.
Features/details:
RWD - 4 Buggy motors, with 2 powering each wheel, they aren't coupled through the center.
Independent suspension on all wheels, front uses efferman's printed wishbones.
Servo steering
Anti-roll bars
3rd party electronics and custom battery pack link for the curious
Total non-Lego/modified parts:
Wheel hubs made by nicjasno link
Modified 9L links
Printed wishbone pieces link
Printed lower suspension arm pieces link
Printed spherical gear holder (CV joint) link
Modified pneumatic cylinders

^Pneumatic tubes work well to tie down the battery. Excuse the sand, took it offroad for a bit
Oh man, I should never sell my parts after using them like this Enjoy!
