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 needed to adjust the correct gas amount with the regulator. Since the slots on the landing ramp taper slightly, and both height and width are adjustable, the flying cars are easily "caught" and continue along the slot. There should not be curves directly before and after the jump ramp, but rather two straight sections of 342 mm each. A great action spectacle.
