Upgrades in this world

Each stage is 5 levels. Engine and Slingshot share the same price curve, so their early levels cost the same. The full level-by-level table, with the plane’s evolution at each unlock, is on the Manta plane page.

Track	Stages	Levels	First level	All levels total

Engine

Each stage evolves the plane.

Stage	Levels	Adds	Top speed	Cost per level
1	1–5	Base plane	100 km/h	425.29T  → 12.97Qa
2	6–10	Left Wing	100 km/h	30.48Qa  → 929.61Qa
3	11–15	Right Wing	100 km/h	2.18Qi  → 66.63Qi

5	21–25	Engines	100 km/h	11.22Sx  → 342.23Sx

Slingshot

Every level adds +0.4 launch power: 22 base, 30 maxed.

Stage	Levels	Launch power reached	Cost per level
1	1–5	24	425.29T  → 12.97Qa
2	6–10	26	30.48Qa  → 929.61Qa
3	11–15	28	2.18Qi  → 66.63Qi
4	16–20	30	156.57Qi  → 4.78Sx

Income

The multiplier doubles every stage.

Stage	Levels	Multiplier reached	Cost per level
1	1–5	×5.87M	100  → 506
2	6–10	×11.74M	759  → 3,844
3	11–15	×23.49M	5,767  → 29,193
4	16–20	×46.98M	43,789  → 221.68K
5	21–25	×93.95M	332.53K  → 1.68M

Engine is the money pit: 99% of the 604.04Sx it takes to max this world. Income pays for itself fastest, so keep it ahead of the other two.
