Algodoo

Smaller version of my spring Boxer engine from a while back, still maintaining the characteristicly massive torque from the engine style.

Clutch is toggled on A,
Gears on 1, 2, 3, & 5.

A key difference from the 10m scale is that the cams are out of phase with eachother, so the engine is self-starting.

To stop (stall) the engine, engage 1st and 5th.
