Following on from my 1m scale Ross engine with gearbox, here's the 10m scale, supercharged version.
Simply connect the orange disc to the drive train of something.

Engine controls:
Hold Q briefly for clockwise spin.
Hold A briefly for anti-clockwise spin.
Press Z to stop the engine.

Gearbox controls:
Gears are cycled through 1-6, each on a toggle.
- Be sure to deselect the current gear before changing gears.

The blue disc will resonate slightly whilst in 6th, hence connecting the orange disc, which won't experience the same resonance.
