What happens when you have a Boxstock Mini 4WD going over a Tamiya Japan Cup Junior Circuit Slope Jump section at full speed (~4.3m/s) with no brakes?
Here is what our jump simulator shows at 0.1X (slow motion). We can also see the bounce effect of the car when landing.
What do you think? Do you agree with the result?
