Rusty,
You had made
mention of the prop being set at a high pitch angle, and that you were going to
reduce the pitch thinking that was part of the prop oscillation problem.
Did you reset the pitch angle? If you did then apparently that was not the
problem.
FWIW You
might give some thought to adding mass to the engine. This might be a
situation where you could be adding weight to the wrong end of the vibration
problem.
I like the
weather station, for some reason I thought it would be warmer in Florida

changes
Nothing changes
Unfortunately,
it didn’t change a thing wrt the vibration issues, or prop oscillation. Still
shaky around 1000 rpm, severe drive rattle around 1900-2000 rpm (can't bear to
try to find the exact range), and severe vibration from 2500-3100.
From 3300 to 5000 it's pretty smooth, but with the scary prop oscillation
getting worse and worse as the rpm increases.
Not sure what
to try next. I do have a two
blade IVO prop that I could try in place of the 3 blade
Warp Drive, but I’d have
to cut the blades down from 72” to 68” to clear the fuselage tube. The
torque reversals might not be the best thing for an IVO prop either.
I’m starting to fear that someone’s going to get a deal on an
RD-1C drive while I look for another solution,
and build an RV-8.
