Hi Tracy,
Congratulations on your first and second
flight.
For getting the information, reading the
instruments, I plug a tape recorder in the co-pilot earphone plug and
talk. It is better than my memory.

Second Flight
After plugging the connection to the EFIS1 Pitot port I made
another flight today. The OAT was about 8 degrees cooler so -
surprise - my oil & coolant temps were about 8 degrees cooler
too. That and a working ASI made this flight a lot more
comfortable.
I did collect a little more data this time but now I
really see the value of data logging. Back on the ground I constantly
find myself wishing I had written down a different sensor reading under a
different condition.
The air temps I'm measuring under the cowl are
much hotter than I want to see, probably due to insufficient CFM of cooling
air. I haven't measured the pressure recovery in my diffusers but
indications are that they aren't going to be what I was hoping for.
Either that or the pressure under the cowl is much too high. Always in
need of more data. Next flight will be made with the dynamic pressure
port probe in place under the cowl.
I'm still a little concerned about
the high turning resistance of my 20B engine when hot. When cool, it
feels normal. This has not changed in 14 hours of engine run time.
Any of you other 20B users notice anything like this. Is there
any significant difference in the way the engine feels when pulling the prop
through when hot and cold?
Tracy
