VPS Peanut BD-4 3D Printed Prop

Designed for Scale appearance.  As tested on my Peanut BD-4.

BD-4 documentation can be found for 2-blade, 3-blade and 4-blade props – make your choice!  The props are para-metrically designed to produce the same blade area, regardless of the number of blades.

Recommended for a ~7 gram model flying on a loop of 1/16″ rubber.

Printed in heat resistant ABS.  These props come with a basic clean-up performed.  They are close to balanced, generally requiring no extra work.

Pre-sale preparation:  these props take about 1 hour to print and about 15 minutes to manually clean up (light scraping and sanding) to get them ready for sale.

These props come with a NOMINAL 1/16″ shaft hole.  This allows the user to bush it appropriately for their prop shaft.

These props DO NOT HAVE A RAMP.  This allows the user to install their favorite clutch.  I recommend a Garami-style or a Boehm-Style clutch.

A Garami-style clutch should utilize a Tube-In-Tube prop shaft.  A Boehm-style clutch only needs one Tube bushed into the prop.

The spinner will have notches indicated for the appropriate blade count.
