【ミニ四駆】バウンシング ストレート Spec.2 BA-BA

[@HardzXElesis]

what's the purpose to have a very high roller set up on the left side on the rear?

same question

[@GalasusID]

I think it's stabilizer, not roller. Mostly to add braking system for lane changer. cmiiw

[@minivictorydonkey]

It is called "Wall Brakes", those brakes only touch the wall when passing a section called "Dragon Coil" or "Hurricane Coil". Due to stiff climb and tight cornering, a machine can easily out of course. To prevent this, wall brakes must only slow down the mini4wd in those sections without losing speed at normal wall height.
