The grass runways I am trying to make have fox-holes nicely aligned on each side. (please look at the screen shot)If I install dirt runways, I do not have the potholes. Also, when I get on or leave either runway, I get a big jump and the engine quits.I tried to play with the altitude of the field and that of the runways, I tried flatten areas from +1 to -4 feet and nothing works. I tried all I could think of even ridiculous solutions as you can see and nothing worksPlease help. I am using Airport version 164 Leon Louis

I don't know if it helps but for all the FS2002 default grass runways MS have made both a dirt runway and a grass runway on top..boneshttp://fsaviation.net
