Is it surger chasis only? Or is it applicable to all flahes? While it does better brakes now, my stock flash still sits in place with its rubber screeching the moment I try to climb even the slightest incline from 0 speed. Any climbing attempt witout a solid starting speed is a guaranteed fail with our current physics model. Is there any way to implement actual torque/grip/whatever it makes ATV actually ATV in real life?
