Ever wanted to hide the thruster inside your ship? If yes, you need to know what is the safe distance for placing blocks again so that you can make the most efficient design. That’s what I want to share with you in this guide!

## Flame Length of thrusters (Max range under Optimal conditions)

### Ion

**Large Ship:**

Small:

Is 2 blocks long and has a flame length of 3, resulting into a total space consumption of 5.

Large:

Is 4 blocks long and has a flame length of 5, resulting into a total space consumption of 9.

**Small Ship:**

Small:

Is 2 blocks long and has a flame length of 2, resulting into a total space consumption of 4.

Large:

Is 4 blocks long and has a flame length of 4, resulting into a total space consumption of 8.

### Hydrogen

**Large Ship:**

Small:

Is 1 block long + 1 conveyor block and has a flame length of 2, resulting into a total space consumption of 4. (And has more power than the small Ion Thruster!)

Large:

Is 3 block long + 1 conveyor block (but has side ports, so with good planing the Conveyor block is not needed) and has a flame length of 6 (!), resulting into a total space consumption of 10(or 9 if designed well).

**Small Ship:**

Small:

Is 1 block long + 1 conveyor block and has a flame length of 2, resulting into a total space consumption of 4. (And has more power than the small Ion Thruster!)

Large:

Is 3 block long + 1 conveyor block (but has side ports, so with good planing the Conveyor block is not needed) and has a flame length of 7 (!), resulting into a total space consumption of 11(or 10 if designed well).

### Atmospheric

**Large Ship:**

Small:

Is 3 blocks long and has a flame length of 1, resulting into a total space consumption of 4.

Large:

Is 5 blocks long and has a flame length of 4, resulting into a total space consumption of 9.

**Small Ship:**

Small:

Is 3 blocks long and has a flame length of 1, resulting into a total space consumption of 4.

Large:

Is 5 blocks long and has a flame length of 4, resulting into a total space consumption of 9.
