  BTW, to make everyone feel better, my EC-2 is doing something I =
haven't been able to explain either.  I have to run with cold start on =
to have enough fuel to run, which would imply that I'm only getting half =
the fuel I'm supposed to get with it off.  I'm sure I've goofed =
something up, and I haven't really taken the time to figure it out yet, =
but I do have a small Holley carb on the way to test as well :-)

  Hi Rusty,

  here is my two cennts. I do not believe that what you see on your =
video has anything to do with the way the engine is running. What you =
described about the prop tips is what every prop does, more or less, =
unless you run it in a wind tunnel with absolute stright airflow. What =
you are seeing is what makes one prop run smoother than another. The =
more flexible a prop is, the smoother it feels. This is why composite =
props generally feel smoother than wood or metal ones.=20
  Just want to give you some caution about the interpretation of the =
video.
  Unfortunately, I can not see it over my telephone line.=20

  (Will be testing with gear box and prop soon.)
