Hi Aerohead,
Do you have an equation that shows the relation between generated Reynolds number for full size objects and those of 1/24th scale?
Just off the top, 480 mph seems too fast for some reason. At a Mach value of 0.3 (225 mph), the air is starting to reach the "non-compressible" zone.
I know I've read here that the turbulent zone is fully established at speeds of only 20 mph or so for full size objects.
Jim.
