It was taken this morning with a Flip video camera during my takeoff run and climb to about 4k msl. OAT was 78. Initially, the mixture was set the same as my last report as indicated by the EM-2's mixture bar. Then I adjusted the mixture a bit richer, toward "best power". Best I can tell, the fuel flow went to 28.6 gph. Sorry for the jerky video but my cameraman had the shakes. I stopped recording when the sun blanked out the EM-2's screen. I need to design a camera mount before I try this again.
Prop was set to 2100 rpm for initial takeoff, then to 1900, and finally to 1700. Max engine RPM (that I can read) was 6926, but dropped back to approx. 6350 as speed increased (prop still set to 2100). You can hear engine rpm drop when I changed prop setting.
It should be noted that the primary oil and water temps are on the EFIS, not the EM-2.
