Full disclosure: My firm manufactures the 2006X oil cooler used on many of your RV-10s and we developed the splitter that some of you use in the oil cooler air box.
This forum provides a great service to those of you building and flying RV-10s, but I am concerned about the trend of providing single data points (ex: oil temps) without supporting test data. I encounter this often in the phone calls from RV-10 owners that are struggling with high oil temps. We are able to solve the problem, but I think more owners could be helped if a standardized approach and test form were used.
If someone writes in and says my temps are XXX without giving OAT on the ground and for each 1000 feet in climb, fuel flow, manifold pressure, take off weight, number of blades on the prop, etc., etc. the information is not as useful as it could be. Yes, you all know your airplanes well and can see trends, but for real problem solving we need standardized data.
For example, a pilot that sits, with engine running, for 15 minutes waiting for a clearance in Phoenix in July is going to have different results (due to heat soak) than someone with the same load that taxis out of his residential hangar and is off the ground in 5 minutes, even with the same ground OAT.
I would be happy to provide a standard PDF Flight Test form similar to what we have used for FAA flight testing the past if anyone is interested. Perhaps there can be an offline place where people can share more detailed data. With modern engine monitors we should be able to come up with some very useful data very quickly.
