Engine is a 100HP Corvair with 66" Warp Drive prop.
For those who mentioned that I was running hot previously, let me note that I cut the openings of the 601cowl to the recommended diameter of 4 7/8" (actually mine missed the mark slightly as I cut it to just 4 3/4") Previously, I had not made the cuts to the nose bowl and my temps got fairly hot.
Here are the numbers I encountered during the high speed taxi and just after the first true flight along with the time of day.
The two high speed taxis were between 11:58 and 12:10. The actual flight around the pattern was just before the 12:30 data (the 12:30 reading was after taxiing for about 4-5 minutes)
