What it does

  • Shroud wraps the fin blades so the spinning prop stays boxed in on your build
  • Angled fin design shaped for a DIY R/C boat propeller setup
  • Coded fin geometry gives this piece a distinct multi-fin shape
  • Compact shroud body fits into your existing R/C boat drivetrain plans
  • Made to order in the USA once you place your order

Shrouded propeller sits on the end of your R/C boat drive shaft, ready to take its place in your build. The fin blades sit inside a round shroud, giving the whole piece a boxed-in look instead of open, exposed blades.

This version, called propellerbetter, comes from a coded, parametric design where the maker set the fin thickness, fin count, and fin angle for this exact shape. You get one specific configuration, built for hobby boat projects that need a shrouded prop instead of a bare one.

It works well for anyone building or upgrading a DIY R/C boat and wants a shrouded propeller shape to test on the water. Pair it with your own shaft and hardware setup to see how it fits your build.
