Last night I plugged in my Reiff sump heater around 8pm. At noon today, my oil temp (at the oil temp sensor) was already at 96 degrees, and my CHT's were at almost 80 degrees. You can see the OAT (outside air temp) sensor said it was 39 degrees in the hangar today at noon. Wow the Reiff system is great.


My engine started right up today, thanks to it being warmed up. I did a clockwise flight around my phase 1 area. Wow it was cold out. You can see on the right EFIS the OAT was 15 degrees F at 5,500'. My oil temps were cold (My tape pulled off of the oil cooler) and I was FREEZING in the RV. Well, dumb dumb me realized once I landed why I was so cold. I latched the canopy at the top, but not the main latch that holds down the sides. I think that caused the sides to ride up a little, letting a lot of cold air in. The temp sensor of the EIS was only reporting 45 degrees and I could see my breath almost the whole flight. There was a cloud layer around 4,500' - 6,000' in my phase I area that kept me from doing any real climb/glide testing.

I landed after an hour and retrofitted the new oil cooler blocker. I then tookoff for some closed pattern work. I did 4 takeoff/landings in 20 minutes on the hobbs! Wow this is a speed deamon. I noticed during the takeoff/landings that my oil temps were around 180 degrees. Perfect.
