Great video, as usual!
I was surprised you didn't look at engine temperatures! Those are the ones that get me most of the time, and I have to look at them all the time. They're above the fuel cocks, and should be between 200-250. I'm always adjusting the radiator to keep them in that interval, and if you switch to coarse pitch, the lower RPMs will have an impact on engine temperature! Same thing when you're on approach, the engine might get a bit too cold and run rough, etc.
I also tend to keep carburettor heat at 2/3 for no particular reason, other than I thought once I was doing great and the engine blew up anyway (it was full open).
On the other hand, I never really notice engine oil temps. Can they overheat/underheat?
Great video!
