Congratulations Paul !

Let us know how the propeller work when you don some more testing and
tweaking.

Actually it worked fine for the short operating range I used this
time. At takeoff it had real good punch (or maybe it was the combo of
220HP engine, electronic ignition...) . And when I reached about 110
kts I had to increase the pitch to keep it from over revving. The
adjustment was smooth and short meaning it had plenty of pitch left
for higher speeds. I kept the RG down and went no more than 120 kts.

BYW the Dynon EFIS-D0 worked well too - agreed with the backup
horizon, speed and altitude meters.
