Jeff,

I have shared all my data with APC, and they have examined some of the CF props I made. For those that know the history of APC, they are continually improving the design of their props based on new data (whether theorized or empirical).

APC uses an injection molded production process....which allows very precise and cost effective production. APC has done some very limited number of props in CF, but it dramatically increases the price, and is not a direction (business model) they have chosen to pursue.

I would encourage everyone to check the APC website which contains quite a bit of info about how the props are designed and made, and share your interests/concerns with APC as they have always been a proactive supporter of competition flying.

Regards,

Dave
