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.E. your
systems should be redundant, big whoop that was a toughie to figure
out. (Are you running two Subaru ECU's with the capability to switch
between in the event of failure in your install?) In any engine
installation there are risks which we seek to minimize. This used to
be called common sense. 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.</smaller></color></fontfamily>
