7/31/2022 Flight test 4 - 2nd attempt

 1/4x20 Baffling screw was laying in the bottom cowl.  Found it was from the #1 cylinder.  Applied blue Loctite and tightened.

Oil appearing to be coming from top case bolts where Adel clamps were installed.  Will retorque and plan on applying Loctite 290 if leak persists.

Oil coming from aft side of the cold air sump.  Will retorque and plan on applying Loctite 290.

Bolus tape came loose on the pilot side strake/wing gap.   Need to decide if roll is mitagated well enough and the wing incidence won't be changing.  Then fill the gap and repaint when the wheel pants are ready.

The IAS Pitot static calibration continues.  Fixing the leak in the nose compartment resulted in an additional 2 knot error.  I replaced the silicon tubing on the static port and will need to retest.  I'll try Jim Weir's test.  http://www.rstengineering.com/rst/articles/KP89JUL.pdf

The compass calibration was completed at MWL.  

Suspect I have swapped the left and right brake sensors as after landing, the right brake was showing hotter than the left brake, despite some heavy use of the left brake.  Will test with a heat gun.

The HDX system / buttonology is still challenging me.  I need to watch training videos again and take notes.  The transponder seems to automatically working now as well.

I did landings at MWL, XBP and T67 using the Navy style oval approach and my landings are much better.  https://youtu.be/SuhStmbUccE

Added 18 gallons of fuel at XBP, flew back to T67 using the AP heading mode and it worked pretty well.  It needs some tuning.  It seems a little unresponsive, but does seem to be working better.  

IAS previous flight:

70 KIAS = 84.1
90 KIAS = 103
100 KIAS = 111.1
110 KIAS = 121.4
120 KIAS = 134.3
130 KIAS = 145


Now:
70 KIAS = 86.2
75 KIAS = 90.3
80 KIAS = 95.4
90 KIAS = 104.3
100 KIAS = 110.7

Stopped testing here to get fuel and remove shredded Bolus tape.
