In this video I update you on my progress with the RC car build. I made some significant changes to the rear subframe since the last video. I have decided to implement a 3D printable dual wishbone suspension system. This is a large improvement over the last version of the car, mainly because the camber of the wheel is now constant irrrespective of the suspension arm angle. This should deliver more grip and even tire wear. Another change I made was positioning the shock absorbers in the center of the wishbones, the provides an even force on the hinge and just more stability overall. My only concern at the moment is the strength of the small plastic knuckle parts, they will be under considerable stress when driving.
Nothing is final of course, and I won’t know how well this works until I take the car for a blast.
