>>6274646The only thing you need are a shit ton of long plates and two 4-stud wide strips covered in tiles.
You could get the shallow angle to work using some technic pieces as "joints" to lock it into a triangle. The long side uses studded technic bricks to attach it to the racing strips.
I might suggest using the thinner 32 long baseplates for the base.
Then a simple system with a rubber band (pink) and a knob to make the activator/starting system.
