If the muffler falls off your rotary no big deal.
Paul Lamar

I can assure you that a muffler falling off (or anything else for that matter) in a pusher canard is a HUGE deal.  Like someone else said, don't ask me how I know.

As far as operating technique, what I've been doing is taking off rich (assuming a low-altitude airport) and then maintaining the EGT I saw at takeoff as I climb.  This means that I continually and gradually lean as I climb.  Once at altitude and in cruise, I do the lean of peak thing.  Before I start my descent, I richen up again to that EGT setpoint from takeoff, and maintain it as I descend which results in a continual and gradual richening during descent.  If I'm not already there, full rich at the landing checklist.  Simple, and seems to work OK.

Kind of blows away all the damn intellectualizing I did yesterday on why absolute EGT values would be hard to use for EFI mixture management.  There is a difference between "perfect" and "good enough."  This easy thing to do is intellectualize to the point that you don't do anything.  The hard thing to do is to go ahead and do a "good enough" implementation, and then continually work at refining the implementation to try to get to "perfect."  Even "good enough" here is better than what 90% of the GA population probably does.

Pilot technique or poor human factors design?  Well, in the past, the technology wasn't there to implement good human factors design.  The flight engineers flying the Connies and DC-7s were just trying to keep those crates in the air anyway they could (anyone ever seen the B-36 flight engineer station at the Air Force museum? -- mind numbing).  But to still be messing with throttle, mixture, prop, cowl flaps, turbo wastegate, etc. in 2002 ain't cool.

I was thinking of a tractor of course.

Here is my design for air cooled VW thermostat controlled cowl flaps.
I intend to use this on my turbo 13B Kis Cruiser with side cowl flaps.
Note That Tony Bingelis thought of this long before I did and published
it in his book Firewall Forward on page 140.
