The hiccup is like a backfire. It really
shakes the engine. You can feel it thru the airframe. But it is quick, like
it was a single event. BUP! Then it is smooth again for a minute or two. Much closer
together if you are in a powered decent.

Don't know about the
hiccup but you can easily calibrate the airspeed. Go to calibration
screen for TAS, adjust the sensor offset parameter to one less than the current
ADC reading. Do this at zero airspeed of course.
I am experiencing an occasional hiccup while in cruise and
more often during a decent under power. I am pretty certain that I saw a
comment on this previously from Tracy
but I have not been able to find it. Can someone set me straight on what
to do about this?
My mixture graph is not working and I will
be sending the EM-2 to Tracy
as soon as he returns from Colorado.
I also show a true airpspeed of 22 mph in the hangar and it seems to be about
that much or a little more in error in cruise. I don’t think I can
calibrate this item?
