This is the simplest 2 way flying machine i have found it has been reliable and very easy to build. the machine can have up to 4 additional blocks on either half of the engine.

For this machine, slime and honey can be used interchangeably. If honey is easier to come by, that is perfectly fine

The material list is:
2 sticky pistons
2 normal pistons
2 observer
8 slime blocks (or honey blocks)

Each return station needs:
5 slime blocks (or honey blocks)
1 sticky piston
