Update 11/27/2022

 The canopy didn't want to latch after adding weather stripping.  I made a new catch for the canopy latch handle.

There was a fair crosswind taking off but I didn't have to hit the brakes so was able to take off in a respectable distance.

The autopilot seemed to be finicky today, not maintaining IAS very well.   Seems like it works fine if the air is smooth but it needs some tuning to operate better in turbulence.

Much of the cold air flowing in the canopy gap has been stopped.  Some cold air is coming through the panel vents and will require a little modification to get them to seal closed better.

I completed 1/2 the sawtooth climbs and descent testing at mid CG.  Oil consumption is negligible despite a tiny leak, still suspect the sump gasket.   The AP needs tuned as it doesn't operate well in turbulence.

Update 11/16/2022

 .8 hour flight confirmed the Hall Effect sensor was working properly again.   The air was turbulent so I didn't do any of the flight testing cards other than test for canard stall speed.  The OAT was close to 30F at 8000'.   I could feel a couple small jets of cold air coming under the front if the canopy above the instrument panel. Also, cold air was coming through the back seat opening where the plans fuel selector mounts, so suspect the air is coming in around the turtle back.

I didn't see oil in the aft cowl, just a little on the aft baffle.   After the oil change and running twice, the oil shows about 7.6 quarts on the dip stick.  One quart had been added after running the engine and filling the filter.  Another quart added after getting the engine up to temp and the oil cooler filled.

EPDM D shaped weather stripping was added to the front and side of the canopy.  Some V-seal was applied to the canopy over the turtle back.

Sanded on the wheel pants a little.

Update 11/7/2022

Checked the following after several weeks of working on the heater control and duct, moving ballast, bleeding brakes, changing oil:

Hot air was coming out of the front duct when checked at 7K', OAT 55F.  The sun was shining so didn't need any heat for the rest of the flight so turned it off.  

Reached 10,500 West of KXBP using the autopilot.  

 Ammeter is not reading correctly after the Dynon software upgrade to 16.4.0.  Contacted Dynon and the vendor.  Dynon recommended restoring the .dfg and .svg files (move them to the root directory and load them using the Skyview "load files" option.

The nose wheel castor Belleville washer needs lubricated again, seems to stick/chatter when it rotates.  Also need to check the upper pivot bolt/bearings.  

A few drops of oil were found in the aft lower cowl again.   Oil was on the AN8 45 coming out of the accessory case near the oil pump adapter.  I got a little more torque on the new oil hose.

The AP worked fairly well but seems to need a little tweaking as occasionally there was some pitch oscillation in minor turbulence.

I remembered to fire up the GoPro and posted one video taking off from T67 and climbing to 10500.  

Noticed #1 CHT was reading >10F cold compared to the other CHT's today with the engine off.  I reseated the probe and checked the spade connections, which seemed tight but were oily. Rechecked and is now reading the same as the others.

Update 11-4-2022

 The panel shows Hobs 39.5 Tach 27.  My flight logs (which include taxi/run up time) are showing 35.7 for Phase I.  The last time I flew was Oct 9th.  I've added up my >50NM cross country flights (mostly in 172's and a Cherokee 140) and have over 50 hours.  50 hours is a requirement towards the IFR certification.  50 hours cross country in the Cozy would be a lot more miles than in a 172.

The Dynon HDX software was updated to 16.4.0, charts and terrain were also updated.  One of the Sandisc USB 32G memory sticks had to be  reformatted after using the chart manager and ejecting it.  I use three sticks (two on board and one spare).  The software update took awhile and afterwards, the Hall Effect Ammeter widget was showing a red x on the screen.  This is one I bought from Crazed Pilot.   In the EMS sensor setup, the sensor type was blank but the right column for label was still showing amps.  An older email from Bill McLagan reminded me he'd sent me a definition file to load.   I re-entered the settings several times to try to match the amperage shown on the bench top power supply.  It seems like the polarity is wrong so an engine run will be done to verify the panel is showing positive current when the alternator is working.  

Several hours were spent in the hangar navigating the menus in the Skyview and IFD. 

With weather changing colder and higher humidity, the prop bolts were retorqued.  Recall I've removed the Belleville washers, lubricated the prop bolt threads with wax and lowered the torque value to 35 ft. lbs.  

I finally got the heater duct/adapter and control cable installed after a lot of trial and error trying to reduce the duct from 2.5" to 2".  The control handle is mounted where the plans fuel selector is on the seat back between the pilot and copilot.  

The Dynon widget color bands were in the yellow for some of the normal values so I tweaked them.  Fuel levels, amperage, voltage were changed and some set to alarm.

I ordered two Single Spotlights from Flyleds and should have them Wednesday.  I'm leaning towards installing the landing/taxi lights in the nose.

Mark Reiger, N716CZ is planning on stopping by on his maiden voyage cross country.  Hopefully, Scott Fish, N78CZ & I can meet somewhere.
