Shrouded Propeller for DIY RC Boats, Fin Shroud Design

Design preview. Rendered from the file, not a photo.
This model is not currently offered as a verified ready to buy print.
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.

What it is made of

Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
