REFLECTOR: Flying Front Vibration

[Ronnie Brown]

The reflex (elevator up) during cruise is normal.  In fact, Alan Shaw
recommended something like 1/2" up when at full throttle, single pilot at
sea level.  Here's a quote from Alan:

At cruise I like a Velocity with 1/2" of reflex single pilot.  This rig
makes
for a faster cruise and slower landing.  Your case may be a little extreme
and
require 1/2 degree less incidence in the canard.  A quick fix is to put a
1/32" washer on both outboard top wing bolts...thus decreasing the
difference
between the incidence angle of the canard and main wing.  This way you can
test fly the change before you go through the hassle of changing the canard.

Like I said, I like a Velocity that requires full forward trim and full
forward stick by the pilot when solo, wide open at sea level.  This will
leave
more elevator authority (flare!) when you are slow and loaded.  It should
also
trim fine at the lower indicated airspeeds of cruise at 8,000' and above.
It's a common problem with new Velocities that the new owners fly in this
unusual mode of solo, full throttle, low altitude and then re-rig there A/C
to
fix this quirk that really just makes things better on the slow end of the
flight envelope.

Flutter tested to 210 knots.  No problem just the canard area and bulkhead
vibration.  This may be a harmonic of some sort in my plane in the canard.
Will be checking the engine incidence at annual in Nov.
