6/26/2023 700 mile trip

 Despite a stationary front hanging around for days, the weather on Monday was enticing enough to depart on a longer adventure.   I flew to RPH, picked up 40 gallons and then off to DHT between and around various SUA's.   At 8500', I was above scattered and broken clouds and descended a little under pattern altitude to land at DHT.  There's a cafe on the field so I had lunch after getting 7 gallons of fuel.  Rather than continue North I decided I'd head back since it was hazy and there were a lot of cumulous clouds.  The weather later in Nebraska was very convective, so that was a good decision.

I'll analyze the oil and DHT temps after uploading the data, but initially appears the oil temp increased as a result of the lower baffle changes.   There's a better balance between 2,3 & 4 CHT's.  1 is still running cooler than the others.  Suspect the air is getting dammed up at the diffuser.

I've pulled the prop off, checked the surfaces of the extension and prop and cleaned them off with brake cleaner.   Waxed the prop bolt threads after checking for galling and torqued them to 35 ft. lbs.  

Also pulled the cowls off and will tweak the lower baffling again as I suspect one of the baffles is impeding airflow to much and is why the oil is running warmer than before.

Oil consumption seems to be good, showing 6 qts on the dipstick.   A few drops of oil out of the breather tube are getting slung back into the aft bottom of the cowl.

The prop has a couple tiny pin head sized paint chips and a little scuffing in a couple spots but overall is in very good condition.


The ADS-B Out works very well.  The track logs showed stations as far away as Houston receiving.  However, the ADS-B In data was suboptimal.   There was a NOTAM in the airspace section for ADS-B data 4000-50000.   Doing some research, found that ADS-B ground stations that provide weather are sparse in NW Texas.  

Here's a link to a map with ground station locations, I'm unsure how up to date it is:

Here's a link to a presentation that has a page with details on types of ground stations:

If I was flying a lot, the SiriusXM Weather would be very nice to have since there's huge gaps of ADS-B IN data coverage in the midwest.
