Sounds like there's a story there Walter <grin>.
Bob's point about noting what rudder force (if any) is req'd in "level"
flight is a good one. The problem with that, though, is that on my
Moose, for instance, my vert stab is offset slightly to the right to
compensate for P-factor. On the other hand, I saw at least one Moose at
Oshkosh where the vert stab was aligned straight with the fuselage. So,
how does one objectively compare rudder force notes with folks?
Anyway, it seems that the airspeed is relative anyway. We all fly a
flight attitude on takeoff and landings, noting, over time, what seems
to be a good Vx, Vy and approach speed. In cruise, it's relative too;
we get "there" when we get "there." ...or so it seems to me.
I do know that I'm no where even remotely close to the speeds posted on
the MAM site for the Moose. Heck, I'd have to have a JATO rocket on the
side to get to those speeds <grin>.

The pitot tube on my Rebel is angled down slightly, even in level
flight. This allows it to still register on landings, even with a high
angle of attack. It does not seem to read low in cruise, though. This
did not happen entirely by design, but during one of my fill-ups a long
time ago.

Hi Scott !
It can be challenging to get accurate airspeed
indications - the Rebels
have had that problem since the beginning. Partly
because of the huge range
of angles they can fly at - one solution has been to
go to a larger dameter
tube for the pitot (I used 5/16" tubing on 2 Rebels -
helped considerably)
Maybe we need a tilting head on the pitot, with vanes
to keep it aligned
with the relative wind, like the flight testing setup on new
aircraft !! ;-) :-)
Good thought on the shims - I've heard several people
say that the DH
Beaver has problems, especially on floats, unless you
change the thrust
line a bit ..... You might want to talk to some
folks with lots of Beaver
mod experience - and let us know what they have to say !

Everyone seems to have a different pitot/static
setup so it is hard to get
any comparisons.
If all Moose tend to cruise nose high, I am
wondering if some more down
thrust (shims) on the engine would be a good idea
(before I fit my cowl)??

Hi Scott,
I don't know the pitch angle but I have noted that
our pitot tube is
pitched up slightly. I became aware of this when
our AS indicator was
reading low. The pitot tube was installed parallel
to the chord so if it is
pitched up, so is the wing. (This is in level,
cruise attitude at cruise
speeds). When I realized that it was pitched up
slightly I began to wonder
if the error in the AS indicator was being caused by
the pitch-up. So far
I have done nothing to correct this. Any ideas?

Have any of you that are flying measured or noted
your pitch attitude in
