Since we had a rare sunny day up here in  Seattle, I went up flying for an=
 hour after going through the mode 3, 6, then autotune and then a little=
 touch up in mode 9, on the ground. It was running  pretty smooth, but sti=
ll does not like full throttle- maybe it's still a bit lean up there, but=
 I'm thinking that maybe the Hushpower is too restrictive- I'm flying on=
  60% throttle, tuning with the mixture knob and the EGT is running around=
 1700, RPM is ~5000, MP- Damn, forgot to note- maybe 17"?. Funny thing, th=
e coolant and oil is down around 110 f at these settings. Definitely need=
 to block some of the cooling air. I don't know if the Dynon airspeed need=
s calibration, I did not have my GPS today, but was only getting about 110=
 MPH at that throttle setting. I did get one thing accomplished- I calibra=
ted my AOA on the Dynon.=20

I'm starting to think about making my own very simple, robust muffler out=
 of 321- pretty much a straight 2" tube within a 4" tube, with some holes=
 and a few very firmly welded baffles. I'll try to get   a drawing out and=
 see what everyone thinks about it.=20


At least no one called the tower to report an aircraft in distress this ti=
me.
