Hi Jarek I checked the Hoffman Prop manual and indeed you are correct.
However all on this list will say 2200 RPM I think.
Expect a drop of 200 rpm for cruise so aim for a drop of 250 momentarily. The
idea is to provide enough clearance for the slide to move into place in the
Centre stem nut
Hi Jarek,
With our newish prop (280 hours, also with aSN that starts with A), we shift
into cruise at about 1800-2000 rpm, and find that when in flight (as opposed to
pitch changes on the ground during run-up), the pull requires a bit more force,
but the lever should only come out about 2-4
In my case, when on the ground before takeoff, I start with flat pitch at
1500 rpm, A fairly easy pull of an inch or so drops the rpm to 1200. A
second more aggressive pull returns the rpm to 1500 rpm. I have noted
over the last fifteen years that in flight the required force has
progressively
Michael,
That convinces me further that my "pull" was ridiculously inadequate. I am
beggining to hope that my troubles are soon going to be over, but can't be
sure of course before trying to do it the way it is demonstrated in your
clip.

Tom and Nigel,
Perhaps that's where the shoe pinches? Perhaps the manner I pull the pitch
change handle needs to be looked into before other reasons are examined
(shaft runout or two bearings not touching the driven plate
simultaneously). It is unlikely that serious
Hi All,
Just some further observation on pitch change.
The pitch change action is usually in three stages. The first is the easy take
up of any slack in the cable until noticeable resistance is felt. The second is
the continued pulling of the lever with some effort (but without pulling the

A picture says a thousand words. That is a really good way to deal with the
questions.
Must be cold there at the moment looking at how Kristen is rugged up.
