I think you will have great difficulty testing this without logging data. I think they have modeled wind. Also, they may have also modeled analog stuttering in the gauges, so your reading is always going to be off within some tolerance if that is the case. Also, different planes will no doubt be impacted by different designs. Some planes you may notice the effect and others, not so much. I think of the 190 in 46', I don't really notice much when rad is open or closed, but 109 I definitely do and actually use open rad to burn speed. Anyway, if there is a way to turn off the wind in the CLoD testing, that would be a good idea.
There is another post by FHT the cowboy guy in fmb section. He made black box script to log data. Maybe you could use that. I would do this test at sea level over the ocean, maybe 50-100 meters. Run the plane up to cruising speed settings with rad full open. Hold it there in level flight and trim. Then toggle the rads closed. Since the rads are modeled separately, then you can do the test for both rad types independently and together to see the different effects. It wouldn't surprise me if this piece got dropped because...Oleg left. He definitely cared about flight models and quality products. But he is working a new job now.
