Well, after crowing about how fast my plane was, seems that crow is also on the menu for me. The first 10 or so flight hours were occupied with some pesky but benign problems, and I can't say how long I went without looking at my GPS groundspeed readout. I was quite content to see 240 kts true through the pitot system, till one day the other things were becoming sorted out and I was doing lots of box turns and big squares in the sky. I kept looking at the GRT wind velocity vector line and seems that whichever way I turned I had a headwind. Sometimes a BIG headwind and 180 degrees away, a not so big headwind. What's with this, and how come my groundspeed is so much slower than my true airspeed?

Yep, you guessed it. I put my static port behind the lower rear corner of the passenger door and smack dab in a nice low pressurre spot. 

Oh well, I now see those formulas for increased airspeed being the cube root of the difference in HP are true after all. It does certainly climb well though. 

32 hrs down now, and 8 to go before I can leave my sandbox in east central Indiana.
