Early morning flight.

I went to the dog track after breakfast this morning. The wind was light and switched around a bit but it was flyable. I got in 3 flights with the .40 powered Primary force and it went well. I timed the run with 90 cc of fuel and got over 6 minutes at 9500 rpm. The plane was a lot slower but still had good control through the maneuvers.Lap times were in the mid 5 second range. I found that the push rod was touching the exit hole in the wing and creating a little binding or sticking. I removed enough wood to clear the pushrod and it feels a lot better now. That may explain the wandering up and down during level flight. Better known as hunting.
