Our carbon variable pitch hubs have been used to set three national aeromodelling records since February 2014. They are priced competitively, easy to use, and will survive hundreds of flights and full load. All hub orders include Teflon washers and one screw adjuster.

This hub is specifically designed for low ceiling flying. It features carefully ground components to achieve the ultimate weight figures, as low as 30 mg if ordered without tubes. This hub features a conventional wound torsion spring to allow optimized flying in Category 1 flying sites. A J&H v2.0 hub was used to establish a United States Category 1 F1R record of 28:02 on September 16, 2017.

Weight: 34 mg with spar tubes.

J&H Aerospace propeller hubs are unavailable at this time. We hope to resume production in 2019.
