Yep I almost got a set or two of them when they were on sale, wish I did. That is the hub that @alexincorsica is using for his project in E-Freeboard Open source Electric Caster
Price on the hoyt motors is a lot but you are paying for reliability even if you beat on them. Hoping they would last over a year of skatepark riding. Also that is the ONLY option I have found between 50 and 63mm motors that are not high KV inrunners or hubs ofc.
