Several of the people on the rotary list seem to know you and think well of your reputation, which is a good thing. So far in your posts I have read however, you have NOT SUGGESTED A SINGLE ITEM that has not been discussed on the fly rotary list prior to your notice.

I have always recommended to my friends that if they didn't have the ability to engineer all the subsystems themselves they were better off with a Lycoming or other proven system. (Although that is no guarantee of sure success) My rotary system will see at least 15-20 hours of ground test on an engine stand that includes the cowling and propeller and full power operation to test cooling and other subsystems. I'm tired of self anointed experts (or actual experts) sniping at a certain design without a true understanding of what they are trying to achieve. If fewer in-air failures of rotary powered aircraft is your only goal, great. Otherwise you are wasting archive space. If you can offer design assistance with parts we need like intake and exhaust systems bring it on. If you exist only to criticize the efforts of others, without specifics, don't waste my time.
