💡 Why This Design?

I built these to solve a few common problems:

  • Messy wiring inside tight avionics bays

  • Poor battery mounting options

  • Lack of modularity between rocket sizes

These sleds keep everything secure, accessible, and clean, whether you're flying a small rocket or a larger dual-deploy setup.
