| Subject: | Re: AA5B vs. AG5B |
Thanks for the replies thus far.
I do have to confess, my AA was tweeked quite a bit (more-or-less within what one
could get away with 30 years ago in our heavily regulated environment). I
had removed the exhaust baffles and cabin steps, sealed most non-moving gaps,
rigged a bit of reflex in both ailerons and flaps (usually flew light so benefited
from shift in center of pressure by less induced drag from wing and trim
drag from elevator.) So, my frame of reference is not accurate (and most had
to be reversed for inspections).
What I DID notice was that I could run and hide from "faster" brand P&C retractables
with ease. From this, I have come to prefer side-by-side comparisons as
the most accurate indicator of differences - real or imagined.
I noticed that the AG actually shows 2 knots higher cruise by book, but EVERYONE
I have ever spoken with notes that the AGs are slower. In the boom years,
genav manufacturers used the book values much like a US car manufacturer - making
ridiculous and unsupportable claims for power/speed.
In my experience, increasing engine power makes for very small increases in speed,
mostly can be seen in climb performance. The big differences (and here I
mean in one knot chunks) usually comes from fixing an aerodynamic problem that
someone didn't know was there.

My AA5B trued at 160 knots before I began major restoration.
