How to Make Radio Control Unit in Satisfactory

Updated 21 Oct 2026 Source Satisfactory in-game mechanics and community documentation, retrieved 21 October 2026 By

Radio control units are an advanced electronics part used in late machinery and the space elevator.

What you need

  • The recipe inputs (heat sinks and related parts).
  • Manufacturers to combine them.

Step-by-step build

  1. Check the exact recipe in-game.
  2. Set up the required input lines.
  3. Feed inputs into manufacturers to make units.
  4. Belt the units to storage or the next line.
  5. Balance every input to the manufacturer.
  6. Add manufacturers as demand grows.

Throughput tips

  • Verify the recipe in-game
  • Keep inputs balanced
  • Belt units to storage
  • Scale with demand

Practical notes

Radio control units are an advanced electronics part, so the inputs are late-game components with their own chains. Check the exact recipe in-game first, since heat sinks and related parts take time to automate. Build every input line before the manufacturers, and balance them all to the machine.

One starved feed idles the manufacturer and the whole line behind it. Units feed advanced machinery and the elevator, so keep a buffer for delivery windows. Scale by adding manufacturers, and overclock the input lines that lag rather than the final machine.

Give the unit line room to expand, because advanced machinery demand only climbs.

The elevator draws these units continuously once the late tiers open, so the line never idles.

Common mistakes

  • Guessing the recipe
  • One input running dry
  • Unbalanced inputs

Frequently asked questions

Radio control unit inputs?

Check the in-game recipe — they combine heat sinks and related advanced parts in manufacturers.
