Create: Aeronautics Weightworks
by GWStudios
Create: Aeronautics Weightworks changes the mass values of Copycats blocks so that builders can use them on airships without adding much weight.
What it does
Most Copycats blocks in Create carry a default mass that adds noticeably to an airship. This addon sets the mass of most of them to 0.01kpg, so decorative and functional Copycat blocks can be used in large amounts while the airship stays light. Blocks that still contribute more mass than desired keep their values only where the author chose to leave them.
The addon is written for Create: Aeronautics and is meant to work with the airplane physics system. Its mass values are standardized, which makes airship weight calculations more predictable for builders. It is a server-side only mod, so players join without installing anything, and only the server needs it.
Installation requires NeoForge and the 1.21.1 game version. The latest file is 1.0.1 for 1.21.1, published on 2026-07-19 after a first release on 2026-06-19.

Key features
Lightweight Copycats
Copycats blocks receive a near-zero mass in the addon, so decorative blocks add little weight to an airship.
Airship-friendly building
Builders can use large amounts of Copycats blocks for decoration and function without the weight growing much.
Standardized mass values
Mass values for the affected blocks are set consistently, so airship weight can be estimated with less guesswork.
