Redstone Flight Control Set

The set's main block family is the PIDer, a processor that takes an input signal, compares it to a target, and outputs a corrected signal. Corresponding input and output blocks let a PIDer connect to a machine and read or drive it. The author's goal was to make PID control available for whatever machine a player is working on, not only for flight. Right-click rotates a full block clockwise, except for the signal passer, and Shift with right-click breaks the mod's blocks along with a few more, including some entities. The configuration menu is opened from the PIDer, and holding Shift shows the description of each function.

The set grew out of Create Aeronautics. Building a working airship with a redstone PID circuit that controls a physical fan-driven propeller took the author days, and the mod is meant to make that kind of build far simpler. Several variants target specific needs: a cross-reading PIDer that controls one axis of an Aeronautics gimbal sensor, a spider PIDer that supplies the full PID signal from the same sensor, and an oscillation detector that outputs a redstone signal when the input passes through zero twice and holds it until the input rises past a higher bound. The configurable output plate can be set to paste anything, and the analog meter reports the signal level.

Installation requires only NeoForge. The server and every player need the mod installed. The latest file, 1.5.2, targets 1.21.1 and was published on 2026-09-24. The mod is not open source and is released under All rights reserved, with a public source code repository and issue tracker. It was first published on 2026-07-24.
