I have F-15E's with a parking radius of 12m and I have other F-15E's with a parking radius of 11m. Then my F-15SG planes have a radius of 9m. What is correct radius? I am not sure why they have different radius' I didn't change anything.

I was looking at the Mountain Home AFB scenery and the parking for the F-15's is set to 10m. So should I change the radius of my F-15's to 10m?

In the real world the actual length of the two-seat F-15s is 19.43 m, so a radius of 10m would fit. It would make sense to make the models fit the radius when the radius is accurate.
