RC Quad-Motor Rally Car Chassis
z3_2drive posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello! I'm back with another MOC, most likely the last one for a long time as I'm rapidly approaching a Lego dark-age of my own (college). This time around I'm finishing off my series of high-speed vehicles with a special rally-style chassis. It is my best handling version so far and it actually has bodywork (more of a tubular rollcage). Details: RC - featuring the custom electronics I've been using for previous versions. Link for those who haven't seen my setup yet. 4 Buggy motors for drive (2 driving each rear wheel, disconnected in the middle). Servo steering (normal Lego servo). 4 Wheel independent suspension - rear includes anti-roll bar and shorter top links while the front has caster and active camber due to shorter top link. Both axles have modified pneumatic cylinders acting as springs+dampers together. Extremely sturdy chassis with little to no twist (I tried hard to twist it from end to end, doesn't budge) plus sturdy rollcage that can be used to pick up the MOC. 3D printed wheels by efferman, as well as 3D printed spherical gear counterparts that act as really strong CV joints. The sturdy construction allows the suspension to work as intended, absorbing every bump. Here is the video: And now for a photo dump: Hope you guys like it! Sorry purists
