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.
