(Same person here, site cut off the message.) The trucks need to be at an angle so that for every degree of rotation that the board makes, the trucks make an equal amount of rotation. The closer the angle gets to 90 degrees, the more rotation there will be in the trucks. Same goes for the opposite. Now, when you reach the territory of 90 degrees, that just won’t work. The trucks can rotate freely with the board’s rotation having no play in how the trucks rotate. Those are just glorified castor wheels at this point.
