Linear zigzag curve with ridges (5-lane Japan Cup custom) - vibration + cornering

30° banked curve. Place 2 banks with corners/straights between them. Steeper banking requires more ground clearance.

45° banked curve. Place 2 banks with corners/straights between them. Extreme banking with severe transition clearance demands.

Angular/stepped hump with sharp edges (5-lane competition). Asymmetric 9°/13° profile, ~21mm height per hump.

Vertical lane changer with a 75° peak. The bridge lane climbs an eased three-segment ramp with an effective base breakover of about 25°, reaches roughly 1000mm of running-surface rise, changes lane at the crest, then descends. The taller support frame seen in footage is not used as driving-surface height.

Vertical lane changer entry ramp (5-lane). Bridge car (L1) climbs a dynamic ramp to the same effective ~1000mm bridge rise used by the full vertical changer. Ramp angle is computed from distance to the matching exit. Non-bridge cars shift flat.

Vertical lane changer exit ramp (5-lane). Bridge car descends from the same effective ~1000mm bridge rise used by the full vertical changer and can bounce at the exit. Non-bridge cars pass through as flat straight.

Steep ~28° uphill climb with about 360mm of effective running-surface rise (5-lane competition section). Stall risk, needs strong torque and enough brake clearance at the crest.

Steep ~28° descent with a mid-slope step (5-lane competition section). The car accelerates downhill, then launches from the step into the receiver.

90° vertical wall section with 30° entry ramp - forces wall-running at racing speed

20° banked curve. Place 2 banks with corners/straights between them to create a banked zone (Bank → Corners → Bank).

Single hump (slope-up into slope-down). Use count=2 for double dragon. 3-lane version is harder than 5-lane.
