The case was taken from Qwsxlt

This is a small airship designed for exploration, adventure, or fast movement between bases. This is the lightest, slowest, simplest and probably the latest version of this airship.
The airship accelerates to 35 m/s and rises to a height of 273. For assembly, you just need to put coal in the chests at the top and portable engines.
The engines consume 720 coals per hour, filling all 6 chests with coal will ensure that the engines run for 28 hours.
The lever to the right of the typewriter turns off the automatic fuel supply, which will allow you to save some coal. To restart, you need to manually add coal to one of the engines again.
