The Apex series, fully ground adjustable hubs are the finest crafted hubs available to the ultralight and experimental market. Made in-house on our Haas VF4 CNC vertical milling station, these hubs offer features that are unavailable on other hubs. By nature of the fact that we own the machine, we can take the time to pack features into these hubs that we couldn’t afford to buy from an outside vendor. The are highly sculpted solid 6061-T6 aluminum, polished silver and are made to the finest CNC machining tolerances in the industry. In fact, we specifically designed the machining process to insure a perfectly balanced prop hub. It takes longer to make Apex hubs, it’s true, but there is no comparison between these hubs and any other offered by our competition.
The multi-blade configurations offered with the new Apex hubs allow us to take advantage of the large reduction ratios offered by Rotax and Hirth in their gearboxes. Also, more horsepower can be loaded into more blades so this may be a solution to some applications that have limited room to turn a propeller.
Hub assembly is non-returnable.
