I think Deakin is worth reading, but some of what he says should be
taken
with a grain of salt. His columns are mostly based on experiments with
his
own highly modified Bonanza, a few high performance radial engines, and
some
theory. In fact, a careful reading of his columns will show no test data
for
the most common engine and propeller combinations in use today.

You've not read hiscolumns about the test beds they've run at GAMI?

I merely point out that his theories are controversial -- they are hardly
universally accepted, as even this thread amply demonstrates. As I said, I
think he has a point, but I have to consider that the engine manufacturers
and aircraft manufacturers might know at least as much about their products
as GAMI does.

No. You do not "merely" point out... You do it in a manner that, intentional
or no, suggests that he is blowing smoke up your backside. You further
appear to completely disregard the supporting data and arguments, both from
GAMI testbeds and from historical operating practices for piston engined
aircraft. He does offer credible arguments that the engine manufacturers
offer recommendations contrary to good engineering and operating practices.

Let's be honest here.

yours,
Michael
