How Much RAM Does a Create Aeronautica Server Need?
Create Aeronautica is a Create pack on NeoForge 1.21.1 built around aerial machinery and flight — players engineer their own functional aircraft, hot air balloons, and aerial transport from Create's rotation and motion mechanics rather than flying a prefab vehicle. See the full details on the Create Aeronautica pack page. Here's how much RAM it actually needs at different group sizes. Finnish players: Minecraft-palvelin hosting is our native-language page. German players: Minecraft-Server mieten covers the same hosting auf Deutsch. Svenska spelare: Hyra Minecraft-server täcker samma hosting på svenska.
4 GB
Bare minimum for solo play or quick testing. NeoForge 1.21.1 plus Create's rotation and motion systems leave little headroom here, and the moment you build an actual flying contraption you'll likely feel it.
6 GB
The best starting point — this matches Create Aeronautica's own recommended RAM floor. Enough room for Create's kinetic simulation to run flying machines without the server constantly scraping the ceiling.
9 GB
A safer bet for a mid-size active group. Once a few players are each running their own engineered aircraft or hot air balloons at once, the extra headroom keeps Create's motion simulation from becoming the bottleneck.
12 GB
For 10+ players or a long-running world with many flying contraptions stacking up. Create Aeronautica worlds accumulate kinetic machinery over time, and a mature build list benefits from the extra room.
