The two parts (each approximately 34 cm) are height adjustable and can be attached to existing straight sections at the desired distance (max. 40 cm). Of course, a bit of practice is required to adjust the right amount of gas with the controller. Because the slots on the landing ramp taper slightly, and both height and width are adjustable, the flying cars are very well "caught" and continue to drive in the slot. There should not be direct curves before and after the jump ramp, but ideally two straight sections of 342 mm each. A great action spectacle.
