【Mini4WD】Verify the difference in speed due to bank through! Brake setting【Mini4Cumaster】 

you dont want brakes touching on banks so best is get a 20deg bank piece to check the setting. usually you sacrifice front brakes on jumps. you can use heat to make the brake sponge thinner at front/rear for clearance

I never thought about dragging a car by hand on a slope that I would take off the track

neo vqs advance pack has brake setting that clears banks out of box.
