Mark,
I tried setting the prop for a more coarse
setting prior to landing like you describe. I probably come in too fast, but
with the prop set like that, I floated in ground effect almost the length of
the runway, then when I added power to go around, I didn’t have much
climb power. I tried it a few times and it was similar each time. I could
probably learn to land that way, but I gave it up and went back to the brake
effect you get with a flat prop when you cut the power.
I will try the learning method you
describe to see if that fixes the surge problem.
You haven’t reported on how your
plane is doing with the new panel???

I also have an M/T
electric prop. I discovered a long time ago that my landings are more
predictable if I switch the prop over to manual mode prior to entering the
pattern. I typically level off about 3-5 miles out, change the prop rpm
to 2100, wait for it to re-adjust itself, then switch to manual mode.
This makes the prop behave like a fixed-pitch, and from this point to touchdown
I fly it like a fixed-pitch prop.
Regarding your surging
issue, Tracy
suggested to me to simulate a landing, but at a safe altitude. Set up as
if you were in the pattern preparing to land, and then put the EM-2 into
auto-tune mode. Let the EM-2 tune the settings which are impossible to
tune on the ground. Worked for me.
Thanks,
Mark

Jack,
I think everybody is waiting for an opportunity to help someone
with a problem. So I am always ready with one that I can use a little
assist on.
I am having an engine surge and wildly fluctuating mixture when I
get into the pattern and reduce the manifold pressure to around 15 inches and
below. I have an MT electric constant speed prop, so my engine rpm at
this time is pretty high, usually around 6K. This is an area that can not
be tuned on the ground and I suspect that is the problem, however, the MAP
table is at the factory setting of zero in areas that I have not tuned.
It can get pretty exciting when it starts so I would like to get it ironed out.
Others having similar problems or how to go about the fix?

HI Jack,
I checked
and found your subscription to be intact. It appears that there has been
no Flyrotary traffic since 11/3. Very strange, indeed... but it happens I
guess. Could be everybody's buttoning down for the winter... we'll see.
