I do notice on the newer composites, that the inlets have

moved out------ away from the spinner, with big lips (top and bottom) to
avoid stalling the airflow entering (or at least avoiding separation)
during climb.

originally, my cowl mocked what I saw at Reno.  the intake extended to
within a 1/4" of the prop.  when I noticed rpm loss on steep climb outs I
cut it back several inches.  I didn't notice any power loss/gain (just seat
of the pants observations) at level flight.  I intended to build a larger
radiused intake, but never did.  so, not everything at Reno should be copied
(for example, tiny rudders).   kevin (that's why it's called experimental
:-)


Then there are cuffs and Paul Lipps props.
